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.[1]
