The original route of the A4018 went from Bristol to Avonmouth via Durdham Down and Shirehampton Road, the main road between Bristol and Avonmouth before the Portway was opened in 1926.[1] 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.[2] 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),[3] linking with the New Filton Bypass which ran from Cribbs Causeway to the A38 north of Patchway. In December 1971 the New Filton Bypass was incorporated into the M5 motorway,[4] and the A4018, by then dualled from Cribbs Causeway to Westbury-on-Trym, became the principal road linking the motorway to west Bristol.


The road runs for 6.1 miles (9.8 km) from the centre of Bristol to the M5 motorway at Cribbs Causeway. The route includes Park Street and Whiteladies Road. It then passes over part of Durdham Down on Westbury Road, then along Falcondale Road and Passage Road through Westbury-on-Trym and Brentry. The final part of the A4018 is Cribbs Causeway, off which is the unusually-named locale of Catbrain.
