|Route outline (key)|
The B4351 is a short link road running from the A438 at Clyro to the town of Hay on Wye.
From Clyro the route heads southeastwards for about a mile before crossing the River Wye and entering Hay, ending shortly afterwards at a T-junction with the B4350.
The B4351 is perhaps the most suitable access to Hay for traffic coming from Hereford via the A438. The B4350 via Clifford provides more a more direct route; however, it crosses the Wye by means of Whitney Bridge, which is subject to both a toll and a weight limit.
