The A48(M) motorway in Wales links Cardiff with Newport. It is a 2-mile (3.2 km) long M4 spur. At St Mellons, it runs continuously into the dual-carriageway A48, which also has (albeit narrow) hard shoulders. The A48(M) has no other junctions and opened in 1977.[1][2] The M4 was extended from junction 29 in 1980.[3]

Previous A48(M) motorways
The 6-mile (9.7 km) Port Talbot bypass which opened in 1966,[2] was numbered A48(M) before its incorporation into the westward extension of the M4 in the 1970s.[4] Some maps show the Morriston bypass section of the M4 as also having been originally numbered A48(M), although whether this number was ever used on the ground has been questioned.[5]
