The A4160 is a road between Cardiff and Penarth in Wales. Its role as the main road between Cardiff city centre and Penarth has largely been superseded by the A4055 and A4232 roads via Cardiff Bay. The route begins at Fitzalan Place on the junction at Newport Road (A4161) and West Grove. It heads south along Fitzalan Place and then westerly along Adam Street and Bute Terrace and for a short stretch south along Bute Street before entering Callaghan Square and joining Penarth Road, continuing in a southwesterly direction. It crosses through the Penarth Road commercial district then crosses the River Ely and passes under the A4232 road, after which it turns to a south easterly direction. It ends in the town centre of Penarth.
