The original northern end of the A48(M) (now a spur of the M4)

Originally the A48 ran through the centre of Port Talbot. In the mid-1960s it was given a bypass (with the old road renumbered A4211). Interestingly, the bypass was built as a motorway and so given the number A48(M). It opened in two stages. The north-westernmost 1.5 miles of the westbound carriageway opened in December 1965, with the remainder of the road opening on 22nd July 1966, making it the oldest motorway in Wales.

The road was renumbered M4 (its current number) in the mid-1970s, presumably to indicate that it would become part of that through route although this road was not extended (in the direction of Bridgend) until 1977. The other end of the A48(M) was a temporary terminus for many years until the River Neath was bridged in the 1990s, making the original northern end of the road into a mile-long spur leading to the roundabout at the northern end of J41.
