Thorp Arch Bridge

Thorp Arch Bridge is a bridge built in 1770, constructed from ashlar magnesian limestone. It features five segmentally-arched spans, with two arches crossing the current course of the River Wharfe, which marks the boundary with Thorp Arch parish. The central arch is flanked by triangular cutwaters that rise to create pedestrian retreats in the parapet, while the other piers have cutwaters that end in offsets. There is a continuous band beneath the parapet, which has chamfered copings.

At the south end of the bridge, located in Boston Spa parish, the west side has been significantly rebuilt, and the east side has a rock-faced retaining wall that supports a widened entrance to the bridge. Both parapets at this end finish with early 19th-century round-ended piers featuring bands. The north end of the bridge, in Thorp Arch parish, ends at square piers, but the east parapet continues with a curving wall that has a rounded end pier, similar to those at the south end.
