Description

The Road Bridge over the River Vyrnwy is a Grade II listed structure built from freestone masonry. It features a plain narrow band below the parapet made of large freestone blocks. The bridge has four regular segmental arches, with rounded cutwaters and plain buttresses above. The two southern arches include tie-rods that run through them, terminating in bolted triangular brace plates. The northern embankment is designed with five low, round-arched flood arches constructed from rubble stone.
