|Route outline (key)|
The A467 used to begin on the A48 in the middle of Newport, and made its way up the east bank of the Ebbw River along what is now the B4591. It had a junction with the M4 at junction 27 (High Cross). Now, the A467 starts on the A48 at junction 28 of the M4, and runs as a dual carriageway on the west bank of the Ebbw.
Tredegar Park - Brynmawr
The road currently starts its journey underneath junction 28 of the M4. Travelling northbound it traces the route of the erstwhile A4072 until it reaches the junction of the A468 at an at-grade roundabout. Continuing northwards there is a grade-separated junction with a spur of the B4591 (whose mainline is the A467's original route) before reverting to a couple of at-grade roundabouts. As we travel north-westwards, the valley sides grow steeper and higher, and by the time we see Risca on the east bank of the Ebbw, our corridor on the west bank is very constrained indeed. At Crosskeys, the dual carriageway ends, and we turn right at a roundabout to remain in Ebbw Vale (the straight on route leads along the B4251 into the Sirhowy Valley). The A467 crosses to the east side of the valley, though still on a relatively new alignment, and we continue north through Abercarn and Newbridge, where a left turn at a roundabout leads onto the A472. Until 1935, this was the end of the A467. We go straight on, multiplexing with the A472 for a short distance (our number is now dominant) to Crumlin where we take on the former route of the A4044.
At Crumlin, we cross the river to the west bank again, the road effectively shoe-horned into the valley next to the river. At Aberbeeg, we reach a roundabout, where we finally say goodbye to Ebbw Vale by bearing right. The A4046 to the left will keep you in Ebbw Vale, but we head north-east towards Abertillery, following the Ebbw Fach River (little Ebbw). Still in a steep-sided valley, we pass the old mining towns of Blaina and Nantyglo, before bearing right at a roundabout to bypass Brynmawr. Our route finally comes to an end at a roundabout on the A465 Brynmawr northern bypass.
