|Route outline (key)
The A4064 is a dead-end route running north into the mountains from Bridgend.
The road starts on the A4065 in Abergarw. Its original route was along the road heading northeast from Abergarw Road as far as the wood, then northwest to reach its current route, which was cut through slightly later, to the south of Llangeinor. The present A4064 splits at its southern end to meet the A4065 twice; the western fork was the first numbered A4064.
Heading north along the valley, the A4064 meets the A4093 in Llangeinor before passing through Pontycymer and finally reaching Blaengarw. The road passes the library before ending without ceremony at a crossroads.
The unclassified road which continues zigzags on out of town before morphing into a forestry track.
