Route

Lower Brynmorgan bridge at Cwm-twrch Uchaf

The A4068 is a relatively short A-road in South Wales.

The road starts in Gurnos at a roundabout on the A4067, which is the main road along the Swansea Valley. Our road heads northwestwards upstream following a tributary, the Twrch, running through the logically named (for Welsh speakers) Cwm-twrch Isaf and Cwm-twrch Uchaf. There is a short one-way loop in the latter, with northbound and southbound roads running on separate banks of the river (northbound traffic has to cross the river twice).

We leave the Twrch behind as we climb through Ystradowen and presently reach open moorland. The road forms the boundary of the Brecon Beacons National Park for about a mile, after which we cross the infant River Amman and follow it to Brynamman. We end in the centre of that village at a mini-roundabout on the A4069.

History

The present incarnation of the A4068 came into being in 1935 by taking over the B4297 from Ystalyfera to Gurnos, then the B4299 from there on to Brynamman. The section of the road through Ystalyfera was duplicated by the parallel A4067 and so when that road was upgraded the A4068 was declassified. It thus now starts in Gurnos.
