Description
Eglwyseg Bridge is a Grade II listed structure made of local carboniferous limestone. It features a hump-back design with a semicircular arched tunnel that is faced with rough voussoirs. The bridge has a rough block coping that ends in a large boulder on the southeast side. The parapet and spandrels are splayed in plan and gradually slope down to blend into the ground.
