Description
Pont Talyrni is a single-span road bridge made of rubble. It features a segmental arch constructed with rough-dressed voussoirs that are recessed under an archring of narrow stones. Above the arches, there are shallow triangular stringcourses. The bridge has a flat carriageway with rubble gable parapets that splay out at the approaches. There are slab openings that contain various scratched graffiti, with the earliest dating back to 1844.
