The A4018 is an A-road from Bristol to a junction with the M5 motorway at Cribbs Causeway. It is one of the three principal roads which link Bristol city centre to the motorway network (the others being the M32 motorway and the Portway).



Until about 1959 only the route from the centre of Bristol to Durdham Down was designated the A4018. The remainder of the route was part of the B4055 (Westbury Road), unclassified (Falcondale Road and Passage Road) and a further part of the B4055 (Cribbs Causeway).[1] In 1959 Passage Road was widened and rebuilt, and by 1962 the route from Durdham Down to Cribbs Causeway was designated the A4018, 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[2], 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 10 miles (16 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.
