Location: Very close to the A470 between Builth Wells and Talgarth. Crosses the River Wye.

Built by David Rowell and Co in 1922. Span 81m, width 2.4m.

Happy Pontist entry here.

Despite appearances (long span, narrow deck, wooden floor), vehicles up to 3 tonnes are permitted to cross the bridge at low speed.

The bridge is of the fully-suspended type (as distinct from the hinged type, of which Rowell & Co's Queen's Park Bridge (Chester) is an example). The ends of the suspended span are able to move slightly within the constraints, as can be seen and heard when a vehicle passes over. Photos 5 - 7 show the constraints at top and bottom. Evidence of fretting and polishing can be seen on the top chord in Photo 7.
