Description
Bont Commins Coch is a single-span bridge constructed of roughly-coursed stone. It features a large segmental arch made of narrow stone voussoirs that are flush with the spandrels. There is a string course along the parapets, which have been rebuilt and topped with rock-faced capstones laid on edge. The parapets are slightly arched, while the deck of the bridge remains flat. The ends of the bridge are splayed out, supported by square end piers that are the same height as the parapets. Boundary walls extend from the piers, except on the southwest side.
