The federal government has allocated $140.6 million to grade-separate Tonkin Highway's intersections with Benara Road, Morley Drive and Collier Road. The funding is part of the five-year phase of the Nation Building Program from 2014–15 to 2018–19. The upgrades are intended to improve freight transportation along the highway.{{cite web|title=Building and Planning for Western Australia's Future|url=http://www.minister.infrastructure.gov.au/aa/releases/2013/May/budget-infra_07-2013.aspx|publisher=Commonwealth of Australia|accessdate=25 July 2013|date=14 May 2013|archiveurl=https://web.archive.org/web/20130728090243/http://www.minister.infrastructure.gov.au/aa/releases/2013/May/budget-infra_07-2013.aspx|archivedate=28 July 2013|url-status=dead}} The total cost is expected to be $281.2 million.{{cite web|title=Tonkin Highway Grade Separation Program|url=http://www.nationbuildingprogram.gov.au/publications/reports/pdf/new_projects/WA_Tonkin_Highway_Grade_Separation_Programnew.pdf|work=Nation Building Program|publisher=Commonwealth of Australia|accessdate=25 July 2013|archiveurl=https://web.archive.org/web/20130728090332/http://www.nationbuildingprogram.gov.au/publications/reports/pdf/new_projects/WA_Tonkin_Highway_Grade_Separation_Programnew.pdf|archivedate=28 July 2013|url-status=dead}} In the lead up to the 2013 Australian federal election, which resulted in a change a government, the Labor candidate for Perth, Alannah MacTiernan, accused the then-opposition's candidate of lying to the electorate over their commitment to the upgrade. The official policy costings did not contain specific funding for the project. However, an opposition spokesperson claimed it was "in the current forward estimates", and not in the costing, as the upgrade was neither a "new and accelerated" project, nor a project that would definitely not be funded.{{cite news|last=Hopkin|first=Michael|title=Alannah MacTiernan: Libs lied over Tonkin Highway funding|url=http://www.westernadvocate.com.au/story/1756897/alannah-mactiernan-libs-lied-over-tonkin-highway-funding/|accessdate=29 September 2013|newspaper=Western Advocate|date=5 September 2013|location=Bathurst, New South Wales|archiveurl=https://web.archive.org/web/20130929041053/http://www.westernadvocate.com.au/story/1756897/alannah-mactiernan-libs-lied-over-tonkin-highway-funding/ |archivedate=29 September 2013|url-status=live}}

The Perth Darwin National Highway (PDNH) Swan Valley Bypass is a highway built to bypass the Great Northern Highway within Perth. From the junction of Reid Highway and Tonkin Highway at Malaga, it heads north towards Ellenbrook, and continues on to Great Northern Highway and Brand Highway in Muchea.{{cite web|title=Perth Darwin National Highway Planning Study (Reid Highway to Maralla Road)|url=https://www.mainroads.wa.gov.au/Documents/PDNH%20Newsletter%20June%202013%20final.RCN-D13%5E23307912.PDF|publisher=Main Road Western Australia|accessdate=18 June 2013|date=June 2013|archiveurl=https://web.archive.org/web/20130728040555/https://www.mainroads.wa.gov.au/Documents/PDNH%20Newsletter%20June%202013%20final.RCN-D13%5E23307912.PDF|archivedate=28 July 2013|url-status=live}} The previously planned route of the PDNH, prior to 2012, followed Lord Street, east of Whiteman Park.{{cite news|last=Frank|first=Caroline|title=New Darwin route|url=http://www.inmycommunity.com.au/news-and-views/local-news/New-Darwin-route/7623855/|accessdate=7 October 2012|newspaper=The Advocate|date=30 May 2012|archiveurl=https://web.archive.org/web/20130728042136/http://www.inmycommunity.com.au/news-and-views/local-news/New-Darwin-route/7623855/|archivedate=28 July 2013|url-status=dead}} The state and federal governments allocated funding to the project, with contracts for the central section awarded to the Great Northern Connect Team on 12 January 2017,{{cite web|title=Stage 2 Contract awarded for NorthLink WA|url=https://www.mediastatements.wa.gov.au/Pages/Barnett/2017/01/Joint-media-statement-Stage-2-Contract-awarded-for-NorthLink-WA.aspx|website=Media Statements|accessdate=20 June 2017|archive-date=26 April 2018|archive-url=https://web.archive.org/web/20180426075716/https://www.mediastatements.wa.gov.au/Pages/Barnett/2017/01/Joint-media-statement-Stage-2-Contract-awarded-for-NorthLink-WA.aspx|url-status=dead}} and contracts for the northern section awarded to CPB Contractors on 30 January 2017.{{cite web|title=Stage 3 contract awarded for NorthLink WA|url=https://www.mediastatements.wa.gov.au/Pages/Barnett/2017/01/Stage-3-contract-awarded-for-NorthLink-WA.aspx|website=Media Statements|accessdate=20 June 2017|archive-date=1 March 2017|archive-url=https://web.archive.org/web/20170301131130/https://www.mediastatements.wa.gov.au/Pages/Barnett/2017/01/Stage-3-contract-awarded-for-NorthLink-WA.aspx|url-status=dead}} Construction started on the central section on 12 June 2017,{{cite web|title=Construction of the central section kicks off|url=https://project.mainroads.wa.gov.au/northlinkwa/newsinfo/news/Pages/centralsectionunderway.aspx|website=Main Roads Western Australia|accessdate=20 June 2017}} and construction on the northern section planned to start late 2017.{{cite web|title=Timeline|url=https://project.mainroads.wa.gov.au/northlinkwa/about/Pages/Timeline.aspx|website=Main Roads Western Australia|accessdate=20 June 2017}} Construction was completed on 23 April 2020.{{cite web|url=https://www.businessnewsaus.com.au/articles/-1b-northlink-wa-road-project-now-open.html|title=$1b NorthLink WA road project now open|website=Business News Australia|accessdate=28 April 2020}}

This section starts at the Reid Highway/Tonkin Highway interchange, which will be upgraded to a cloverstack interchange. Following, to the north, is the Marshall Road flyover, then a two-level roundabout interchange with Hepburn Avenue and Beechboro Road North. Onwards from there is the Baal Street flyover, then at the planned interchange with the Whiteman/Yanchep Highway, the highway veers northeast, meeting up with a partial cloverleaf interchange with Gnangara Road. The highway then follows the edge of Ellenbrook, having a two-level roundabout interchange with The Promenade.{{cite web|title=Northlink WA Ultimate Case|url=https://project.mainroads.wa.gov.au/northlinkwa/Documents/00-NLWA-ULTIMATE-CASE_Long%20Term%20(no%20TGS).pdf|website=Main Roads Western Australia|accessdate=4 January 2017}}

This section was originally planned to be a 2 lane single carriageway with at-grade intersections, but because costs went down, it was changed so it can be constructed as a 4 lane dual carriageway with grade separated interchanges. Continuing on from the roundabout interchange with The Promenade in Ellenbrook, it goes north, passing built up areas in Ellenbrook, then going through rural areas. Along the way are roundabout interchanges with Stock Road and Neaves Road, and a flyover over Muchea South Road and the Midland railway line, and the current Brand Highway, before ending at a roundabout interchange with Great Northern Highway and a new Brand Highway.{{cite web|title=Northern Section Concept Plan|url=https://project.mainroads.wa.gov.au/northlinkwa/Documents/Northern%20Section%20Concept%20Plan.pdf|website=Main Roads Western Australia|accessdate=20 June 2017}}
