| Cardiff Bay|
| Barry Island|
The A4055 is the main road link between Cardiff Bay and Barry.
The road goes through the village of Dinas Powys and there has been a call for by-pass due to the volume of traffic from Barry to and from Cardiff. However the Vale of Glamorgan Council confirmed in June 2007 that the by-pass would have to be funded by the Welsh Assembly Government (WAG).
The road was extended in 1988 from the junction of the A4160 to the Ferry Road Interchange of the A4232, this is called the Cogan Spur and as such it is also a spur road off the A4232.

The road starts from the Cardiff International Sports Village at the Ferry Road Interchange (A4232), then along the Cogan Spur until the junction of Barons Court. From there it goes through Llandough and Dinas Powys. The road then enters the Barry district of Palmerstown along Cardiff Road and goes into Weston Square, Gladstone Road, Broad Street, Harbour Road and finally Friars Road in Barry Island.
