|Route outline (key)|
The A4072 was a short A-road to the west of Newport. The road came into being in 1935 when the B4242 (south of the A468) and B4243 (to the north) were upgraded to Class I status. The southern section of the road was the first stretch of dual-carriageway constructed in Monmouthshire, certainly complete by 1945 as it appears on aerial photography of the time. Later, the A467 took over this section following the construction of the Rogerstone/Risca bypass in 1983, with the remainder of the A4072 declassified, making the number redundant.
Starting on the A48 (and, after 1967, the M4) on the edge of Tredegar Park, the road headed north along Forge Road and soon reached Bassaleg and the A468. There was a short multiplex east over the Ebbw River (this section has now been severed by the present line of the A467) before the A4072 regained its number on the far side of the railway line at Pye Corner, turning north where the A468 turned south.
The road continued north along Tregwilym Road alongside the railway line, crossing it twice before reaching Rogerstone. It headed north along St John's Crescent to end on the original A467 (now B4591).
