History

Built in the C18, probably before 1794 when the crown was raised by 15in (38cm) and partly rebuilt by Thomas Penson, surveyor, to carry a minor road over the Penybont ravine and falls. The bridge was apparently known to George Borrow as Glyn Bin.

Exterior

Built of local rubble stone. A single segmental arch spanning approximately 11m between rock abutments, the soffit rising to c18.0m above water level. The arch is formed of 50cm deep rubble voussoirs slightly set in under a projecting regulating course, above which flush spandrels extend up into a flush stone-coped parapet, now provided with safety wires. The width of the bridge between parallel sides is 5.6m, providing a 4.7m width level carriageway between the parapets, which splay slightly outwards at the ends to terminate in square piers.

Reasons for Listing

Included as a fine and little altered country bridge dramatically spanning the ravine containing the Penybont falls. Of group value with the adjoining listed section of the Holyhead Road.
