Description
Pont yr Henblas is a bridge constructed from local rubble stone. It features three closely spaced rectangular openings that pass diagonally under the road, with each opening measuring approximately 1.2 meters wide and 1.5 meters high from the water level to the slate capping slabs. Each water pier is protected on the upstream side by a selected boulder cutwater. The flush spandrels rise into low flush stone-coped parapets, with the northern parapet curving at the western end.
