The A403 is a main road linking Bristol with the Severn Estuary. It runs from junction 1 of the M48 at Aust to the docks at Avonmouth. After the Severn Bridge was opened in 1966, the A403 was constructed in 1969 and 1970 to provide a direct route between the M4 motorway and Avonmouth. It is an important route for the local industries, allowing easy access between Wales and this part of England. It was financed by Gloucestershire County Council with a £387,000 grant from the Ministry of Transport and was initially known as the Avonmouth Aust Coast Road.{{cite web|url=https://api.parliament.uk/historic-hansard/written-answers/1965/dec/14/classified-road-programme|title=Classified Road Programme|work=Parliamentary Debates (Hansard)|date=14 December 1965|access-date=8 August 2016}}
Route
The road is {{convert|8+1/2|mi}} running through South Gloucestershire and the City of Bristol. Between the M4 at Aust and Pilning it replaced the B4055 on a realigned route. Between Pilning and Chittening it followed a new route beside the ICI Severnside plant, and from Chittening to Avonmouth it followed the route of an existing unclassified road, St Andrews Road. At Avonmouth it connects with the A4, leading to the Portway.{{cite web|url=https://www.google.co.uk/maps/dir/51.6001863,-2.6184635/51.5038938,-2.697814/@51.5050825,-2.6968269,15z|title=A403, Bristol|publisher=Google Maps|access-date=8 August 2016}} The road disrupted local communities, with Pilning being split in two sections.{{cite web|url=http://www.bafhs.org.uk/bafhs-parishes/other-bafhs-parishes/159-northwick|title=Northwick|publisher=Bristol & Avon Family History Society|access-date=8 August 2016}} It runs near the proposed Avonmouth and Severnside Enterprise Area, planned for expansion by Bristol City Council. When completed, the road will have a junction with the M49 motorway (Junction 1) reducing the amount of heavy traffic passing through local communities.
Safety
Around 8,000 vehicles a day use this road. Although this is relatively low, a high proportion of traffic consists of heavy goods vehicles (HGVs); over five times the average.{{cite web|url=https://consultations.southglos.gov.uk/consult.ti/legacy_1507/consultationHome|title=A403 and Aust Village – Casualty Reduction Scheme|publisher=South Gloucestershire Council|access-date=8 August 2016}}{{cite web|url=https://www.bristol.gov.uk/streets-travel/a403-improvements|title=A403 improvements|publisher=Bristol City Council|access-date=8 August 2016|archive-url=https://web.archive.org/web/20160823020708/https://www.bristol.gov.uk/streets-travel/a403-improvements|archive-date=23 August 2016|url-status=dead}} The A403 has had a poor safety record with numerous accidents. A particular problem has been HGVs parked at laybys along the road obscuring the view ahead, leading to several fatalities. South Gloucestershire Council reduced the speed limit on their section to 50 mph in 2007.{{cite news|url=http://www.gazetteseries.co.uk/news/11073548.Killer_Aust_lay_by_to_be_closed/?ref=mr|title=Killer Aust lay-by to be closed|newspaper=Gloucestershire Gazette|date=13 March 2014|access-date=8 August 2016}} Bristol City Council have announced plans to install better facilities for cyclists along the road.
