It is a {{convert|2|mi}} long, M4 spur. At St Mellons, it runs continuously into the dual-carriageway A48, which also features (albeit narrow) hard shoulders. The A48(M) has no junctions and opened in 1977.[1] [2] The M4 was extended from junction 29 in 1980.
Previous A48(M) motorwaysThe {{convert|6|mi|adj=on}} 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.[3] 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.[4] References1. ^Pathetic Motorways – A48(M) 2. ^1 The Motorway Archive – M4 Dates {{webarchive|url=https://web.archive.org/web/20070314031013/http://www.iht.org/motorway/m4walesstat.htm |date=14 March 2007 }} 3. ^Pathetic Motorways – A48(M) Port Talbot Bypass 4. ^Pathetic Motorways – A48(M) Morriston Bypass External links{{Attached KML|display=inline,title}}
