|Route outline (key)|
The A4065 is a short urban A-road north of Bridgend.
It starts in Tondu at traffic lights on the A4063 and then heads in a northeast/easterly direction, going under two railway bridges in quick succession, the first carrying the Maesteg branch line and the second a disused freight line. After going through Brynmenin the second is crossed again at a clearly unused level crossing just before a narrow bridge across a stream.
The two forks of the A4064 are then met, after which the road crosses the River Ogmore and turns southwards. It bypasses Bryncethin (although originally it went through the village), to end at traffic lights on the A4061.
