|Route outline (key)|
The B4282 is an "inter-valleys" road in Glamorgan, connecting Cwm Afan in the Afon valley north of Port Talbot to Cwm Llynfi in the Llynfi valley by way of Bryn and the town of Maesteg. The road was originally unclassified but had gained its number by 1932.
The road starts at a signalized Y-junction opposite the centre of Cwmafan on the A4107, which ascends the east side of the valley from Port Talbot. From here the B4282 heads eastward across the hills, climbing steadily for some 5.5 km to reach a summit of 246 m above sea level about 1.5 km west of Maesteg before descending into the Llynfi valley.
In Maesteg the route runs directly into the A4063, by which it is subsumed for just over 200 m as the major road crosses to the east side of the river. Turning right at the end of Talbot Street to regain its number, the B4282 heads first southeastward and then south, following the left bank of the river through the village of Garth. After re-crossing the river and passing under the railway by Garth station, it ends at a second junction with the A4063 in Cwmfelin.
