The A4081 is a short section of A-road connecting the A483 in Llandrindod Wells to the A470 - the main north-to-south road through Wales. It provides convenient access from Llandrindod Wells to the A470 for traffic heading north. Travelling into Llandrindod Wells, the A4081 divides on the outskirts of the town, both routes leading to the A483, one in the town centre, the other to the north.
