TheA4018 is anA-road connecting thecity centre ofBristol to theM5 motorway atCribbs Causeway. It is one of the four principal roads which link central Bristol to the motorway network (the others being theM32 motorway, theA38 and thePortway).
The A4018 runs for 6.1 miles (9.8 km), starting at a junction with theA4 andA38 atThe Centre, and finishing at junction 17 of theM5 motorway atCribbs Causeway. The route includesPark Street andWhiteladies Road. It then passes over part ofDurdham Down on Westbury Road, then along Falcondale Road and Passage Road throughWestbury-on-Trym andBrentry. The final part of the A4018 is Cribbs Causeway, nearCatbrain.[1] Part of the road forms the boundary for the Westbury-on-Trym electoral ward in Bristol.[2]
The original route of the A4018 went from Bristol toAvonmouth via Durdham Down and Shirehampton Road, the main road between Bristol and Avonmouth before thePortway was opened in 1926.[3] By the 1940s only the route from the centre of Bristol to Durdham Down was designated the A4018, and the remainder of the route had been redesignated the B4054.[4] In 1959 Passage Road was widened and rebuilt, and by 1962 the route of the A4018 was extended from Durdham Down to Cribbs Causeway along the former route of the B4055 (Westbury Road), unclassified roads (Falcondale Road and Passage Road) and a further part of the B4055 (Cribbs Causeway),[5] linking with the New Filton Bypass which ran from Cribbs Causeway to theA38 north ofPatchway. In December 1971 the New Filton Bypass was incorporated into the M5 motorway,[6] and the A4018, by thendualled from Cribbs Causeway to Westbury-on-Trym, became the principal road linking the motorway to west Bristol.[7]
Sites close to the route of the road includeBlaise Castle, anIron Age hill fortification.[8]
