Caerleon Road, Llanfrechfa

The B4236 is a semi-rural B-road in western Monmouthshire.

It starts at a roundabout on the A4042 near Llanyrafon, in the Cwmbrân urban area. From here it goes southeastward through Llanfrechfa and Ponthir, where it crosses the Afon Llwyd. It then crosses the Welsh Marches Line twice and enters Caerleon.

Originally there was a multiplex along the A48 (renumbered A449 in 1935) along Caerleon High Street. When the A449 bypass was built to the east the B4236 took over this road and now it is part of a one-way loop in the town centre. Northbound traffic follows this original route whereas southbound traffic follows Mill Street and Castle Street. The two directions combine just before crossing a bridge over the River Usk.

On the far side of the river is a TOTSO. The B4596 (former A449) carries straight on but the B4236 turns left as it always has. It climbs Old Hill before rounding the escarpment and continuing up the steeper Belmont Hill. At the top the road bends right then left before going over the M4 into the Coldra area of Newport. It ends shortly afterwards on the B4237 (former A48).
