:Great Northern Highway

Great Northern Highway is the main north-south route between Perth and the northern areas of Western Australia. Covering a distance of {{convert|3195|km}}, it is the longest highway in Australia.{{cite press release |last1=Briggs |first1=Jamie |last2=Nalder |first2=Dean |title=Shorter Travel Times on Australia's Longest Highway |url=http://www.minister.infrastructure.gov.au/jb/releases/2014/April/jb025_2014.aspx |publisher=Minister for Infrastructure and Regional Development, Commonwealth of Australia |date=9 April 2014 |access-date=23 June 2014 |archive-url=https://web.archive.org/web/20140623084823/http://www.minister.infrastructure.gov.au/jb/releases/2014/April/jb025_2014.aspx |archive-date=23 June 2014 |url-status=live}} {{Cite web |url=http://minister.infrastructure.gov.au/jb/releases/2014/April/jb025_2014.aspx |title=Shorter Travel Times on Australia's Longest Highway |access-date=24 March 2017 |archive-date=9 December 2015 |archive-url=https://web.archive.org/web/20151209193149/http://minister.infrastructure.gov.au/jb/releases/2014/April/jb025_2014.aspx |url-status=bot: unknown }} From Midland in Perth's north-east, the highway heads generally north-east through the Wheatbelt and Mid West to Newman, north-west to the coastal Pilbara town of Port Hedland, along the coastline to Broome, east to Halls Creek, and finally north to Wyndham, on the state's northern coastline. {{convert|60|km|mi|spell=In}} out from Wyndham, the highway intersects the start of Victoria Highway, which carries interstate traffic to the Northern Territory via Kununurra. Various road routes are allocated to sections of Great Northern Highway, which is mostly a National Highway route, and also forms part of Australia's Highway 1. It is signed as National Route 1 from Midland to Middle Swan, National Highway 95 and National Route 1 concurrently from Middle Swan to Muchea, National Highway 95 from Muchea to Mundabullangana, National Highway 1 from Mundabullangana to Victoria Highway, and State Route 155 from Victoria Highway to its northern terminus at Wyndham. The vast majority of the highway is a two-lane single carriageway, although {{as of|2014|lc=y}} there are thirteen single-lane bridges and four single-lane floodways in the Kimberley.{{Google maps |url=https://www.google.com.au/maps/dir/-31.886096,116.005579/-15.46499,128.100081/@-22.7807442,122.3024323,2212918m/data=!3m1!1e3!4m11!4m10!1m6!3m4!1m2!1d116.022972!2d-31.787986!3s0x2a32b5e1681dca4d:0x1304f0b526a30350!4e1!1m1!4e1!3e0?hl=en |access-date=12 February 2013}}{{cite news |title=Kimberley Zone Fights for Double-lane Bridges |url=http://www.abc.net.au/news/2014-05-30/kimberley-zone-fights-for-double-lane-bridges/5489704 |access-date=24 June 2014 |work=ABC News |publisher=Australian Broadcasting Corporation |date=30 May 2014 |archive-url=https://web.archive.org/web/20140603074016/http://www.abc.net.au/news/2014-05-30/kimberley-zone-fights-for-double-lane-bridges/5489704 |archive-date=3 June 2014 |url-status=live}} {{Cite news |url=http://www.abc.net.au/news/2014-05-30/kimberley-zone-fights-for-double-lane-bridges/5489704 |title=Kimberley Zone fights for double-lane bridges |newspaper=ABC News |date=30 May 2014 |access-date=24 June 2014 |archive-date=1 November 2016 |archive-url=https://web.archive.org/web/20161101064045/http://www.abc.net.au/news/2014-05-30/kimberley-zone-fights-for-double-lane-bridges/5489704 |url-status=bot: unknown }} The speed limit is {{convert|110|km/h|mi/h|round=5}} except in and around built up areas.

The key industries of mining, agriculture, and pastoral stations are all dependent on the highway as a significant and in some cases only method of transport. Tourism accounts for a significant portion of the road's traffic, and is a growing part of or potential growth source for the regional economies. The highway provides access to a variety of tourist attractions, including New Norcia and various national parks, including Karijini.{{cite web |title=Kimberley Regional Profile |url=https://www.mainroads.wa.gov.au/Documents/Kimberley%20Regional%20Profile%202013-14.RCN-D14%5E23137815.PDF |publisher=Government of Western Australia |access-date=23 June 2014 |author=Main Roads Western Australia |archive-url=https://web.archive.org/web/20140510025337/https://www.mainroads.wa.gov.au/Documents/Kimberley%20Regional%20Profile%202013-14.RCN-D14%5E23137815.PDF |archive-date=10 May 2014 |url-status=dead |year=2013 |df=dmy-all }} {{webarchive |format=addlarchives |url=https://www.mainroads.wa.gov.au/Documents/Kimberley%20Regional%20Profile%202013-14.RCN-D14%5E23137815.PDF |date=1 January 1970}}{{cite web |title=Wheatbelt North Regional Profile |url=https://www.mainroads.wa.gov.au/Documents/Wheatbelt%20North%20Regional%20Profile.RCN-D13%5E23631257.PDF |publisher=Government of Western Australia |access-date=23 June 2014 |author=Main Roads Western Australia |archive-url=https://web.archive.org/web/20131227005748/https://www.mainroads.wa.gov.au/Documents/Wheatbelt%20North%20Regional%20Profile.RCN-D13%5E23631257.PDF |archive-date=27 December 2013 |url-status=live |year=2013}} {{Cite web |url=https://www.mainroads.wa.gov.au/Documents/Wheatbelt%20North%20Regional%20Profile.RCN-D13%5E23631257.PDF |title=Archived copy |access-date=22 June 2014 |archive-date=26 December 2013 |archive-url=https://web.archive.org/web/20131226124415/https://www.mainroads.wa.gov.au/Documents/Wheatbelt%20North%20Regional%20Profile.RCN-D13%5E23631257.PDF |url-status=bot: unknown }}{{cite web |title=Mid West Regional Profile |url=https://www.mainroads.wa.gov.au/Documents/Midwest%20Regional%20Profile%202013.RCN-D13%5E23432526.PDF |publisher=Government of Western Australia |access-date=23 June 2014 |author=Main Roads Western Australia |archive-url=https://web.archive.org/web/20140123125034/https://www.mainroads.wa.gov.au/Documents/Midwest%20Regional%20Profile%202013.RCN-D13%5E23432526.PDF |archive-date=23 January 2014 |url-status=live |year=2013}} {{Cite web |url=https://www.mainroads.wa.gov.au/Documents/Midwest%20Regional%20Profile%202013.RCN-D13%5E23432526.PDF |title=Archived copy |access-date=22 June 2014 |archive-date=3 March 2016 |archive-url=https://web.archive.org/web/20160303233252/https://www.mainroads.wa.gov.au/Documents/Midwest%20Regional%20Profile%202013.RCN-D13%5E23432526.PDF |url-status=bot: unknown }}{{cite web |title=Pilbara Regional Profile |url=https://www.mainroads.wa.gov.au/Documents/Pilbara%20Regional%20Profile%202013.RCN-D13%5E23728690.PDF |publisher=Government of Western Australia |access-date=23 June 2014 |author=Main Roads Western Australia |archive-url=https://web.archive.org/web/20140426045938/https://www.mainroads.wa.gov.au/Documents/Pilbara%20Regional%20Profile%202013.RCN-D13%5E23728690.PDF |archive-date=26 April 2014 |url-status=dead |year=2013 |df=dmy-all }} {{webarchive |format=addlarchives |url=https://www.mainroads.wa.gov.au/Documents/Pilbara%20Regional%20Profile%202013.RCN-D13%5E23728690.PDF |date=1 January 1970}} Parts of the highway itself are included in the tourist routes Swan Valley Tourist Drive (Tourist Drive 203) in Perth, Chittering Valley Tourist Way (Tourist Drive 359) in Bullsbrook, Midlands Tourist Way (Tourist Drive 360) from Upper Swan to Walebing, and Geikie–Windjana Tourist Way (Tourist Drive 350) from Geikie Gorge National Park to Fitzroy Crossing.{{cite web |title=Tourist Drives of Western Australia |url=http://www.tourism.wa.gov.au/Publications%20Library/Tourist%20Drives%20of%20WA.pdf |publisher=Main Roads Western Australia |access-date=3 November 2013 |author=Main Roads Western Australia |author2=Western Australian Tourism Commission |author3=Royal Automobile Club |archive-url=https://web.archive.org/web/20110404120927/http://www.tourism.wa.gov.au/Publications%20Library/Tourist%20Drives%20of%20WA.pdf |archive-date=4 April 2011 |url-status=dead |pages=7, 8, 15, 37}}

Overall, Great Northern Highway performs favourably in terms of road safety, compared to other major highways in Western Australia. Whilst making up two thirds of the state's National Highway network, it was the location of only half of all recorded fatalities for 2005–2009. For that period, the sections of the highway from Wubin to the Sandfire Roadhouse, north-east of Port Hedland, were considered by the Australian Automobile Association to be among the lowest risk highway links in the state. However, the section from Perth to Wubin was rated as medium risk, and the northern sections of the highway were rated medium-high and high risk.{{cite web |url=http://www.aaa.asn.au/documents/reports%2F2012%2FAusRAP-report-2011-How-Safe-Are-Our-Roads.pdf |title=How Safe are our Roads?

The highway heads north through Middle Swan, intersecting the start of Toodyay Road after {{convert|1.3|km|1}}, and then the meeting point of Reid and Roe Highways after another {{convert|1.4|km|1}}. Those highways come together from Perth's ring road, signed as State Route 3, and north of this intersection Great Northern Highway is concurrently allocated National Highway 95 and National Route 1. It continues north through the Swan Valley for {{convert|9.5|km|0}}, passing many wineries, restaurants, and other tourist attractions. The highway crosses the Swan River and intersects West Swan Road, before turning north-east to travel around the residential part of Upper Swan. Great Northern Highway continues north for {{convert|spell=in|13|km|0}} beyond West Swan Road, past larger agricultural properties, to reach Bullsbrook, the last urban area within the Perth Metropolitan Region. After {{convert|11.5|km|0}} beyond Bullsbrook, the highway reaches the edge of the Perth metropolitan area at the City of Swan–Shire of Chittering boundary, where it passes into the Wheatbelt.{{Google maps|url=https://www.google.com.au/maps/dir/-31.8860446,116.0055686/-31.8754365,116.009892/-31.8640956,116.0139692/-31.7800115,116.022226/-31.6699084,116.0308282/-31.6019846,116.0105718/-31.5767239,115.9959914/@-31.7081544,116.0182467,11z/am=t/data=!3m1!4b1!4m9!4m8!1m0!1m0!1m0!1m0!1m0!1m0!1m0!3e0 |access-date=20 June 2014 |title=Great Northern Highway: Midland to Muchea |link=no}}

In the Wheatbelt, Great Northern Highway links small town sites with the surrounding rural farmland, occasionally passing by remnant patches of woodlands.{{Google maps |url=https://www.google.com.au/maps/dir/-31.5767239,115.9959914/Bindoon+WA/-31.3493385,116.1156612/NEW+NORCIA/-30.6947664,116.2118027/-30.6263624,116.3649862/-30.491591,116.3622771/-30.4138584,116.6580616/-30.2766966,116.6639401/-30.1055496,116.6304408/@-30.7495851,116.3308432,9z/am=t/data=!3m1!4b1!4m22!4m21!1m0!1m5!1m1!1s0x2bcd1612aad4dfb9:0x400f6382479e2c0!2m2!1d116.0964945!2d-31.3860661!1m0!1m5!1m1!1s0x2bcda7980e2fca29:0x400f6382479e570!2m2!1d116.2131191!2d-30.9733981!1m0!1m0!1m0!1m0!1m0!1m0!3e0 |access-date=21 June 2014|title=Great Northern Highway: Muchea to Wubin|link=no}}

From the north-eastern edge of Perth, the highway travels north for {{convert|spell=in|3|km|0}} to Muchea. At Muchea the road curves to the west to approach a roundabout interchange with both Brand Highway and Tonkin Highway. Unlike other interchanges in the outskirts of Perth, Great Northern Highway is not free flowing with the interchange configured to have an overpass connecting the northern continuation of Great Northern Highway with Tonkin Highway to the south instead. Traffic wanting to continue on Great Northern Highway needs to turn right at the roundabout to continue northwards while southbound traffic needs to exit the main carriageway and turn left at the roundabout. Brand Highway and National Route 1 continues to the west of the roundabout. There is also a Road train assembly area in the southeast quadrant of the interchange.

Great Northern Highway and National Highway 95 then continues north-east for {{convert|26|km}}. It passes to the west of Lake Chittering, curves east to cross the Brockman River, and then back north to Bindoon. {{convert|spell=In|5|km|0}} further north, Bindoon–Moora Road branches off to the north-west, while the highway skirts east briefly then continues north, reaching New Norcia after {{convert|46|km}}. The starting point of The Midlands Road is located at Walebing, {{convert|35|km}} further north; from there, Great Northern Highway heads north-east for {{convert|18|km}} to Bindi Bindi, north for {{convert|17|km}} to Miling, then east for {{convert|33|km}} to the northern end of Northam–Pithara Road, and shortly thereafter Pithara. From here, another {{convert|16|km|0}} takes the road to Dalwallinu, and Wubin is {{convert|20|km}} further north.{{cite map |publisher=Government of Western Australia |author=Main Roads Western Australia |title=Wheatbelt North Region Map |date=13 August 2013 |url=https://www.mainroads.wa.gov.au/Documents/REGION%20STATE%20ROAD%20CONDITION%20MAP%20138%20138%20WHEATBELT%20NORTH.RCN-D13%5E233477.PDF |version=Version 1.0 |scale=1:721,154 |access-date=20 December 2013 |archive-url=https://web.archive.org/web/20131006145331/https://www.mainroads.wa.gov.au/Documents/REGION%20STATE%20ROAD%20CONDITION%20MAP%20138%20138%20WHEATBELT%20NORTH.RCN-D13%5E233477.PDF |archive-date=6 October 2013 |url-status=live |df=dmy-all }}

As Great Northern Highway heads north-east from Wubin out of the Wheatbelt, the vegetation changes to arid shrubland. In the Mid West region, the long stretches between settlements show few signs of human activity, other than the highway itself. The first such settlement is Paynes Find, {{convert|154|km}} out from Wubin. At this point the highway heads north again, reaching Mount Magnet after {{convert|143|km}}, and then Cue after another {{convert|80|km}}.

It proceeds north to Marble Bar, mostly as an unsealed road, whilst the highway deviates north-west, reaching Newman after {{convert|3|km|spell = in|0}}. The flat landscape gives way to gentle ranges, which the highway meanders around as it heads west-north-west for {{convert|109|km}}. It then curves around to the north, proceeding over a distance of {{convert|48|km}} to Karijini Road, the entrance road to the Karijini National Park. The highway continues north for another {{convert|35|km}}, travelling through the north-eastern corner of the national park to Nanutarra Munjina Road. Great Northern Highway proceeds on its journey north, crossing the Yule River and its tributaries. The highway then runs parallel to the Turner River over a {{convert|220|km|adj=on}} distance until it reaches North West Coastal Highway. This junction is the northern terminus of the National Highway 95, and Great Northern Highway continues north-east as National Highway 1 – part of Australia's Highway 1, which is signed as National Route 1 along North West Coastal Highway. The turnoff for Port Hedland is {{convert|32|km}} north-east of the intersection, and from there the highway heads east for {{convert|40|km}} to the northern end of Marble Bar Road, reaching Pardoo after another {{convert|72|km}}. It parallels the coastline thereafter, passing into the Kimberley region shortly after the Pardoo Roadhouse.{{Google maps |url=https://www.google.com.au/maps/dir/-23.4012678,119.7945427/-23.3732229,119.7781728/-23.3605904,119.7543187/-23.0413249,118.8345093/-22.6684833,118.7014914/-22.3766642,118.6929076/-20.5705409,118.4370445/-20.3568062,118.6230845/-20.382433,118.9738865/Pardoo+WA/@-21.6143001,119.1157784,8z/am=t/data=!3m1!4b1!4m17!4m16!1m0!1m0!1m0!1m0!1m0!1m0!1m0!1m0!1m0!1m5!1m1!1s0x2b8a68dd7c32eae3:0x400f6382479ca80!2m2!1d119.5972138!2d-20.2178802!3e0?hl=en |access-date=21 June 2014 |title=Great Northern Highway: Fortescue River to Pardoo |link=no}}{{cite map |publisher=Government of Western Australia |title=Upper Regions Map: Kimberley, Pilbara and Gascoyne |date=13 August 2013 |url=https://www.mainroads.wa.gov.au/Documents/REGIONAL%20ROAD%20CONDITION%20MAP%20UPPER%20REGIONS%20MAP.RCN-D13%5E2343348.PDF |version=Version 1.0 |author=Main Roads Western Australia |access-date=24 January 2014 |archive-url=https://web.archive.org/web/20140201134426/https://www.mainroads.wa.gov.au/Documents/REGION%20STATE%20ROAD%20CONDITION%20MAP%20138%20138%20MID%20WEST.RCN-D13%5E233479.PDF |archive-date=1 February 2014 |url-status=live |scale=1:3,000,000 |df=dmy-all }}

From Pardoo, Great Northern Highway travels north-east, paralleling the coastline for {{convert|455|km}}, and passing Eighty Mile Beach near the Sandfire Roadhouse. The vegetation becomes denser woodlands once more as the highway heads into the Kimberley's tropical monsoon climate. At Roebuck the highway turns east, heading inland, while Broome Roads spurs off to the west, connecting to Broome. After {{convert|145|km}}, the highway crosses the Fitzroy River on Willare Bridge and reaches the turnoff for Derby, Derby Highway, in Willare. Great Northern Highway continues east for {{convert|217|km}} to Fitzroy Crossing, where it crosses the Fitzroy River a second time. It continues east, curving around the southern side of the Margaret River, and reaching Tanami Road after {{convert|272|km}}. The town of Halls Creek and the Duncan Road turnoff are {{convert|17|km}} north-east of there. From here the highway heads north for {{convert|313|km}}, past Warmun to Victoria Highway.{{Google maps |url=https://www.google.com.au/maps/dir/Pardoo+WA/-17.8481502,122.5027641/-17.6337029,123.7387565/-18.2006861,125.5695383/-18.3244723,127.5546442/-18.2229253,127.6700902/-15.868445,128.372147/-15.8341865,128.3117278/-15.4861049,128.1207418/-15.4567973,128.103681/@-17.0147416,124.0116237,6z/am=t/data=!3m1!4b1!4m17!4m16!1m5!1m1!1s0x2b8a68dd7c32eae3:0x400f6382479ca80!2m2!1d119.5972138!2d-20.2178802!1m0!1m0!1m0!1m0!1m0!1m0!1m0!1m0!1m0!3e0?hl=en |access-date=21 June 2014 |title=Great Northern Highway: Pardoo to Wyndham |link=no}} The national highway route turns off at Victoria Highway, travelling past Kununurra to cross into the Northern Territory.{{cite book|title=Distance Book|year=2013|publisher=Main Roads Western Australia|isbn=978-0-7309-7657-8|pages=4–5|url=http://www.mainroads.wa.gov.au/UsingRoads/TouringWAMaps/Pages/DistanceBook.aspx|edition=13th|access-date=9 May 2014|archive-url=https://web.archive.org/web/20121024075225/http://www.mainroads.wa.gov.au/UsingRoads/TouringWAMaps/Pages/DistanceBook.aspx|archive-date=24 October 2012|url-status=dead|df=dmy-all}} Great Northern Highway, however, continues north-west without a route number, passing the eastern end of Gibb River Road after {{convert|8|km|0|spell = in}}, and reaching Wyndham following another {{convert|48|km}}.

The name Great Northern Highway was first proposed in October 1940 by the state's Nomenclature Advisory Committee,{{refn|group=lower-alpha|Now the Geographic Names Committee{{cite web|title=Geographic Names Committee |url=http://www.landgate.wa.gov.au/corporate.nsf/web/Geographic+Names+Committee |publisher=Government of Western Australia |access-date=22 March 2014 |author=Western Australian Land Information Authority |archive-url=https://web.archive.org/web/20130802165311/http://www.landgate.wa.gov.au/corporate.nsf/web/Geographic%2BNames%2BCommittee |archive-date=2 August 2013 |url-status=dead |df=dmy-all }}}} to describe the main route from Midland to Geraldton, Western Australia.{{cite news |url=http://nla.gov.au/nla.news-article46744914 |title=Midland Junction Affairs |newspaper=The West Australian |location=Perth, WA |date=23 October 1940 |access-date=22 March 2014 |page=3 }} This was following the naming of the Great Eastern and Great Southern highways.{{cite news |url = http://nla.gov.au/nla.news-article67277690|title = Local and General|newspaper = Geraldton Guardian and Express|date = 24 October 1940|access-date = 22 March 2014|page = 2}} The Midland Junction Municipal Council approved the name, however at the Geraldton Municipal Council meeting, one councillor suggested that Great Midland Highway would be a better name. The reasoning was that Geraldton was in the centre of the state's coastline, not in the north. It was explained that the highway would continue north past Geraldton, and the council voted to approve the name.

By July 1941, the Nomenclature Advisory Committee's proposal had expanded to three highway names for the roads in the state's northern areas: Great Northern Highway for "the road from Midland Junction Town Hall to Wyndham, via Walebing, Pithara, Wubin, Payne's Find, Mt. Magnet, Cue, Nannine, Meekatharra, Roy Hill, Nullagine, Marble Bar, Mulyee, De Grey, Pardoo, Wallal, Anna Plains, Le Grange, Broome, Derby, Noonkanbah, Fitzroy Crossing, Christmas Creek, Louisa Downs, Hall's Creek and Turkey Creek", North West Coastal Highway for "the road from Geraldton to De Grey, via Northampton, Galena, Carnarvon, Boolaganoo, Winning Pool, Giralia, Yanrey, Onslow, Peedamullah, Mardie, Karratha, Roebourne, Whim Creek, Mundabullangana and Port Hedland", and Geraldton Highway for "the road from Walebing to Geraldton via Mingenew".{{cite news |url=http://nla.gov.au/nla.news-article47153477 |title=Northern Highways |newspaper=The West Australian |location=Perth, WA |date=23 July 1941 |access-date=22 March 2014 |page=6}}{{refn|group=lower-alpha|Modern-day The Midlands Road and Brand Highway}} The proposal was well received by the local municipal councils and road boards.{{cite news |url = http://nla.gov.au/nla.news-article67313098|title = Local and General|newspaper = Geraldton Guardian and Express|date = 31 July 1941|access-date = 22 March 2014|page = 2}}{{cite news |url = http://nla.gov.au/nla.news-article67312173|title = Greenough Road Board|newspaper = Geraldton Guardian and Express|date = 14 August 1941|access-date = 22 March 2014|page = 4}}

The name Great Northern Highway was gazetted on 10 March 1944, under section 10 of the Land Act, 1933–1939.{{Gazette WA|title=The Land Act, 1933–1937: Naming of Highway|file=1944/11|page=1944:165|date=10 March 1944|url=https://www.slp.wa.gov.au/gazette/gazette.nsf/searchgazette/A50B3BCCDBA73B5C48257727007C5D0C/$file/gg011.pdf|format=PDF}} However, the highway was mostly a series of tracks through remote pastoral areas, with the sealed road ending just past the Wheatbelt town of Miling in 1950.{{efn|1=Between 1926 and 1928, the newly formed Main Roads Board (predecessor to the Main Roads Department, later renamed Main Roads Western Australia) took over control and maintenance of the road from Midland Junction to Meekatharra, and twenty-one other important roads, which were declared "main roads". To increase the usability of the overall main road network, the work schedule for these roads prioritised sealing the worst individual segments, rather than any one road. For example, in 1928/29, twenty-two separate sections of the Perth–Albany road were improved, but the whole route was not completed until 1939.{{rp|27–28, 435}}}}{{rp|120}} Driving was difficult and hazardous all year round. The road was very dusty in the dry season, and some sections of the road were effectively impassable sand, while other sections contained limestone outcrops that damaged tyres. During the wet season, when rivers flooded, sections of road were essentially bogs, or worse still, were completely washed away.{{cite book |first = Leigh|last = Edmonds|title = The Vital Link: A History of Main Roads Western Australia 1926–1996|publisher = University of Western Australia Press|location = Nedlands, WA|year = 1997|isbn = 1-875560-87-4}}{{rp|120–121}}

Economic growth and development in Western Australia's northern regions in the 1940s prompted the state to quadruple road funding between 1946 and 1952. Five "gangs" of workers were allocated to a {{convert|2600|km|mi|adj = on}} length of Great Northern Highway between Meekatharra and Wyndham. However, given the vast distance the highway travelled, and destructive cyclones in the Pilbara and Gascoyne that could destroy multiple weeks worth of work, the overall improvement was relatively insignificant. Over time, though, the road was improved.{{rp|120–121}} New alignments were constructed, such as between Derby and Fitzroy Crossing in the late 1940s, which had originally followed the curve of the Fitzroy River, along its floodplain, and could only be used in the dry season. The new alignment was a more direct {{convert|290|km|adj=on}} section, with the first {{convert|8|km|0|spell=in}} sealed, a total of {{convert|109|km}} of gravel road, and the remainder simply formed earth. Despite this low construction standard, the road remained passable except for short periods during heavy rain.{{rp|120–121}}

In 1961, the federal government passed the Western Australian Grants (Beef Cattle Roads) Act 1961, known as the Beef Roads Scheme, that encouraged road building in the Kimberley.{{rp|168}} This had followed on from an earlier federal grant scheme in 1949 for the construction of a road from Nicholson to Wyndham.{{Refn|Modern-day Duncan Road|group=lower-alpha}} The road allowed trucks to efficiently transport cattle to port, rather than the slow cattle drives that could lose stock and take weeks to complete.{{rp|122}} The 1961 Beef Roads Scheme initially included upgrading the Wyndham to Halls Creek section of Great Northern Highway as one of three projects in the region. One year later the scheme was expanded to include the Broome to Halls Creek section of the highway, and several bridge construction projects.{{rp|168}} However, the resources allocated to Great Northern Highway were needed to maintain the highway as an unsealed road in a usable condition, rather than to completely seal the roadway. In 1963, work was completed on stabilising a {{convert|68|km|adj=on}} sandy section to prevent vehicles from becoming bogged, a {{convert|47|km|adj=on}} section was realigned to avoid the Fortescue River floodplain, and {{convert|40|km}} between Marble Bar and Port Hedland was also realigned to minimise the effects of wet weather.{{rp|186}}

The projects funded by the Beef Roads Scheme resulted in a noticeably higher quality road in the Kimberley,{{rp|221}} but work still progressed on other sections of the highway. In 1970, a single-lane sealed section was completed between Perth and Meekatharra. The project was one of the first in the state to be constructed by contractors rather than by Main Roads directly. It cost $9 million, two-thirds of which was spent after 1959.{{rp|220}} The next section to be upgraded and sealed was from Meekatharra to Newman, a {{convert|414|km|mi|adj=mid|-long}} project that would take four and a half years to construct. Due to the remoteness of the location, airstrips were built alongside the highway, so that workers could be flown in from Geraldton. The highway was realigned in several spots, to avoid difficult areas, improve river crossings, or give drivers a more scenic view of the surrounding area. New bridges were constructed along the route, including a reinforced concrete bridge at the Fortescue River, and a four-span bridge over the Gascoyne River's Middle Branch. By December 1978, the sealed road reached Newman, with the project completed three months ahead of schedule, and at a cost of $20 million, $1 million under budget. With a {{convert|7.4|m|ft|adj=mid|-wide}} seal and {{convert|2.4|m|ft|0|adj=mid|-wide}} shoulders, the road could easily accommodate two lanes of traffic. Previously sealed sections, totalling {{convert|485|km}} of the highway, were less than half that width. Premier Charles Court opened the new and improved highway on 12 December 1978.{{rp|297–9}}

The two-lane sealed road between Halls Creek and Wyndham was also completed in 1978. It involved the construction of 21 bridges, and extensive earthworks designed to blend the road into the terrain. The section was opened on 23 July 1978 by the Minister for Transport, at a cost of over $20 million.{{rp|299–300}} Meanwhile, work on sealing and upgrading the {{convert|476|km|mi|adj=mid|-long}} section from Port Hedland to Broome began in 1976. With up to five contractors and four Main Roads teams working throughout the project, it was completed at an extraordinarily rapid pace. It opened in April 1981 at a cost of $56 million. With the opening of this section, tourist traffic escalated. Cape Keraudren, Eighty Mile Beach, and Broome became increasingly favoured destinations, especially for residents of the Pilbara.{{rp|301}}

Work accelerated in the 1980s as part of the Australian Bicentenary Road Development program. From October 1982, the program provided $2.5 billion to upgrade the country's roads in the lead up to Australia's bicentenary in 1988.{{rp|302}} By this time, the only sections of Great Northern Highway yet to be sealed were a {{convert|275|km|adj=on}} stretch from Fitzroy Crossing to Halls Creek, and another {{convert|416|km}} between Newman and Port Hedland.{{rp|314}} Construction of the Fitzroy Crossing to Halls Creek section began in October 1981. The route had been surveyed in 1979; with the collaboration of the Western Australian Museum, Main Roads ensured it would not impact important Aboriginal heritage sites. After five years of work, including the construction of nine bridges, the widened and sealed section was completed on 7 September 1986. At the time, this was the final section of the nationwide Highway 1 to be sealed, and there was national interest. The media captured the completion on camera, while the federal Minister for Transport, Peter Morris, together with the Western Australian Minister for the North West, Ernie Bridge, rode on the bitumen truck for the final spray.{{rp|318–20}} With this section completed, the Newman to Port Hedland section of Great Northern Highway was the only significant section of unsealed highway in Western Australia.{{rp|320}}

A realignment of the highway between Newman and Port Hedland had been proposed since 1976, which would see the road deviate to the west at Newman, and travel via Wittenoom instead of Marble Bar.{{rp|238}} In the early 1980s, eleven route corridors were investigated by Main Roads. The potential impacts on the natural environment, regional economy, tourism, and resident population were considered, with particular concern for the crossing of the Hamersley Range.{{rp|362–5}}

As the highway would pass through the Hamersley National Park,{{refn|Renamed Karijini National Park in 1991{{cite web |author1=Department of Conservation and Land Management |author2=National Parks and Nature Conservation Authority |title=Karijini National Park Management Plan No. 40 |url=http://www.dec.wa.gov.au/pdf/nature/management/karijini.pdf |page=1 |publisher=Government of Western Australia |year=1999 |access-date=25 June 2014 |archive-url=https://web.archive.org/web/20110312061348/http://www.dec.wa.gov.au/pdf/nature/management/karijini.pdf |archive-date=12 March 2011 |url-status=dead}}|group=lower-alpha}} the Environmental Protection Authority decided in 1983 that an Environment Review and Management Program report was required for the Newman to White Springs section. Consultants prepared the report for Main Roads, which found that the key risks were erosion, visual impact, and possible damage to flora. A detailed survey was carried out, which included the use of laser and infra-red measuring devices from within a helicopter, and numerous field trips to determine the final alignment and bridge sites. A comprehensive Environmental Impact Statement was then produced, and the project was approved in mid-1984.{{rp|362–5}}

In early 1986, the contract for this {{convert|12|km|adj=on}} segment through the Munjina and Mungina East gorges was awarded. Construction of this segment involved tight control over earthworks and machinery movements, to protect the National Park ecology. The finished road was a scenic route curving down through the Munjina Gorge and out onto the Fortescue River flood plain, with cuttings and embankments blending it in with the natural environment. It was opened on 12 June 1987 by the federal Minister for Transport, Peter Morris, having cost $28.4 million.{{rp|362–5}}

Other portions of the Newman – Port Hedland link were completed over the next two years,{{refn|group=lower-alpha|The contractors involved in the construction of the route between Newman and Port Hedland were Leighton Contractors, F.K. Kanny and Sons, Thiess Contractors, John Holland Group and Henry Walker Contracting.{{cite journal|title=The Dream Becomes Reality |date=March 1990 |journal=Western Roads|volume=15 |issue=1 |page=1 |publisher=Main Roads Department |location=Perth, Western Australia}}}} with the last part officially opened on 16 December 1989 by Bob Brown and Bob Pearce, the federal and state transport ministers. This last section of Great Northern Highway also completed the sealing of the National Highway,{{rp|362–5}} and the opening ceremony, held on location {{convert|212|km}} south of Port Hedland, received national media coverage.{{rp|362–5}}

In the late 1960s, Main Roads investigated alternative crossing points over the Fitzroy River, to replace the existing low-level bridge at Yeeda. Flooding in January 1966 had demonstrated that Willare was the best site. The new route would be {{convert|13|km|0|spell=in}} longer, and required two bridges, but would result in a better quality road. When tenders were called, the river flooded again, washing away {{convert|52|m}} of the old bridge. Rather than reconstruct the low-level crossing, the construction timeframe was shortened from 18 months to 38 weeks. The {{convert|390|m|ft|adj=mid|-long}} Willare Bridge and {{convert|200|m|ft|adj=mid|-long}} Minnie River Bridge opened on 12 June 1968, having cost almost $700,000. While situated {{convert|2.1|m|spell = in}} higher than the worst known flood level, the single-lane bridges were designed to accommodate more extensive flood levels, with the water flowing over them if necessary.{{rp|221}}

By the early 1980s, it was clear that the Fitzroy River crossing was still inadequate. Seasonal flooding had closed the road several times, and damaged the embankments leading up the bridges. The crossing had been closed for twenty four days in 1982; while in 1983, the most severe flooding since 1914 extensively damaged {{convert|2.6|km}} of the highway, closing it for twenty-five days. To alleviate the problem, two new bridges were built in 1985, and the road was widened and raised {{convert|2|to|3|m|spell = in}} above the flood plain. The earthworks for the project included constructing guide banks to direct excess water to flow over floodways, which were protected with rocks. This was designed to minimise the time the road would be closed in such a scenario. The $11 million upgraded crossing was opened on 19 December 1985 by the federal Minister for Transport, Peter Morris. Then, one month later, Cyclone Hector produced 70% more water than the crossing had been designed for. Water overflowed the road all along the flood plain, not just at designated floodways, ravaging the shoulders and then destroying sections of road. {{convert|spell=In|4|to|5|km}} of the highway was washed away, leaving the bridges isolated and disconnected. The road was closed from 27 January to 14 February 1986, with $200,000 spent just to make the crossing passable. It was then redesigned and rebuilt at a cost of $1.9 million to make it more flood resistant.{{rp|315–8}}

Despite the provision of a completely sealed road, there was still much work to be done on the highway, with many older sections either worn out or not up to modern standards. Narrow sections were widened to a full {{convert|spell=in|7|m}}, and repairs made to the road, shoulders, fencing, and line markings as required, with work carried out in sections and progressing along the length of the highway.{{rp|366}} Four overtaking lanes were constructed between Mount Magnet and Cue in 1991; and between 1991 and 1993, there were eight contracts awarded to widen, reconstruct, and seal a combined total of more than {{convert|190|km}} of the highway.{{rp|366}}

A range of projects were carried out across the length of the highway between 1996 and 2006. By 1998, a {{convert|157|km|adj=on}} section between the Sandfire Roadhouse and Victoria Highway had been improved at a cost of $1.1 million, and another {{convert|42|km}} north of Meekatharra was improved for $12 million in 1999. Two bridges were constructed in the vicinity of Halls Creek in 2000, and another four in 2004/05, replacing floodways so that the highway would remain open during floods. Similarly, {{convert|100|km}} north of Halls Creek, the {{convert|240|m|mi|adj=mid|-long}} Jarlalu Bridge over the Ord River was constructed to replace a single-lane floodway, and was opened in January 2003. That same year, the bridges over the Fortescue and Gascoyne Rivers were strengthened to increase the highway's load capacity. Modifications were made to the steep ascent of the Darling Scarp at Bindoon Hill between February 2002 and April 2003, and Great Northern Highway was realigned to bypass the Dalwallinu town centre.{{cite book|last1 = Edmonds|first1 = Leigh|title = The Vital Link: The Transition Years 1996–2006|date = 2008|publisher = Main Roads Western Australia|location = East Perth, WA|isbn = 978-0-7309-7692-9|pages = 24–25, 28–29}}

The first stage of construction was undertaken as part of the NorthLink WA project. Tonkin Highway's original northern section was made grade separated, and a dual carriageway extended from the original northern end of Tonkin Highway (near Reid Highway) past Ellenbrook and through the Swan Valley to an interchange with Great Northern Highway and a new part of Brand Highway, with the extension continuing on as Great Northern Highway.
