Pont Blaen Cwm Du, Libanus
Pont Blaen Cwm Du and its Tollhouse were built as part of the Brecon to Swansea Turnpike Road. Construction of the turnpike was begun shortly after the formation of the Breconshire Turnpike Trust in 1767. To the south-east of the bridged are the remains of the Cwmdu Gate Toll House. In 2020, winter flooding caused the partial collapse of the bridge, which has now been restored thanks to Powys Highways.
