A remnant of Merthyr's past. This bridge carried a railway line that either took you through a tunnel to Aberdare or sent you north towards Cefn Coed and on to Brecon via Torpantau. Under the bridge was the Merthyr to Cardiff Glamorganshire canal which carried the produce of Cyfarthfa iron works to the ports of Cardiff which was then shipped all over the world.

Nice ascent from Crosskeys, but watch out for very overgrown pathways on the Machen side. Great views from the top!

A wooden drawbridge carried the road over the canal and was replaced by a fixed bridge after navigation on the canal ceased in the 1930s. Before the canal reopened to boats in 1970, a steel drawbridge with an electric operating mechanism was installed. There are four other drawbridges along the canal to the west. They are for farmers to access fields and are less elaborate than the one at Talybont. Drawbridges saved the canal company the expense of building stone bridges over the canal at these locations.

This is a nice stone bridge along the cyclepath just outside Merthyr Tydfil which makes a pretty spot to stop and take a picture.

Absolutely loved the Taff Trail and it's contrasting scenery, starting in the mountains and Reservoirs of the Brecon Beacons through the working towns of the valleys and into the urban streets of Cardiff City. Fantastic contrast of landscapes industrial past and present. This trail is a must visit if you are in the area.
