|Route outline (key)|
The B4235 is a largely rural B-road in east Monmouthshire.
Originally it started in the centre of Usk on the A48 (later A449) Monmouth Road. The town is now bypassed, however, and so the first section of the B4235 has been upgraded to become part of the A472 link to the A449 eastern bypass.
The B4235 now starts on the A472 nearly a mile to the east of Usk. It heads northeastwards and soon crosses the A449 (access is provided via the A472). After passing Slough the road changes direction and heads more south than east, climbing via Llangwm before zigzagging and descending again via Gaerllwyd to Mynydd-bach where it reaches a winding river valley, which is followed for a short distance.
