Bigsweir Bridge

Bigsweir Bridge is a Grade II* listed structure featuring red sandstone ashlar for the bridge abutments and land spans, while the river span is made of cast and wrought iron. The abutments are part of a causeway that rises to provide headroom over the river. There are two semi-circular flood arches on either bank. The wall is coped and topped with plain cast iron railings that run between circular stone piers. The abutment is slightly wider than the causeway and includes a cornice and parapet. A tollhouse is attached to the northwest side of the causeway, though it has been altered. The bridge has a single elliptical river span measuring 164 feet (50 meters), supported by four cast iron ribs. These arch ribs consist of sixteen segments and were cast in Merthyr Tydfil. A continuous cast iron parapet carries the railings, and the spaces between the ribs and the parapets are open, criss-crossed with diagonal wrought iron tension bars. The bridge remains largely unaltered, except for being converted into a single carriageway to prevent excessive use. The eastern half of the bridge is located in St Briavels Civil Parish, Gloucestershire.
