Hayle Causeway

Hayle Causeway is a causeway with bridges that carries a road over the Hayle River estuary, dated 1825. It features granite rubble walls and granite ashlar with dressed granite copings. The causeway is elliptical in shape and includes bridges at both ends: a 7-span bridge over the River Hayle at the west end, which was widened in the 20th century on the north side, and a single span bridge over a stream at the east end. The main 7-span bridge is constructed of granite ashlar, with round arches and semi-circular piers that form cutwaters. The parapet has been raised using the original chamfered coping stones. The single span bridge at the west end has a round brick arch. The original parapets of the causeway feature chamfered copings and round-on-plan terminal copings at the east end, while the widened causeway at the north side of the west end has a 20th-century parapet.
