B4237

This article is about the current B4237, the former A48 through Newport.
For the original B4237 on the edge of the city, see B4237 (Maindee - Docks).

George Street, Newport

The B4237 follows the 1964 route of the A48 through Newport, bypassing the city centre to the south. It received this number on the opening of the Newport Southern Distributor Road in the 2000s.

Starting at a roundabout on the A48 by Tredegar Park the road crosses the Ebbw River and heads northeastwards into town along the residential Cardiff Road. We cross a couple of railway line, with a retail park between the two, then the B4240 bears off to the left into the city centre. We continue to follow Cardiff Road until a set of traffic lights where that road bears left along the now-unclassified original route of the A48.

Our road follows the dual-carriageway George Street, passing to the south of the city centre. The central reservation disappears as we climb to cross an S4 bridge over the A4042 and the River Usk. The road becomes D2 again on reaching ground level and follows Wharf Road under the railway line to England to reach a T-junction. The old A48 (now the B4591) comes in from the left and we TOTSO right.

We now continue east along Chepstow Road through the suburbs of Maindee and Beechwood before climbing through Lawrence Hill. Presently the B4236 comes in from the left then the houses disappear and we pass the entrance to the Celtic Manor golf course. The road ends just round the corner at the large roundabout at M4 J24, where the A48 and A449 are also met.
