Sunderland Bridge originally carried the Great North Road (A1) across the River Wear, and probably dates back to the 14th century. It is built of dressed sandstone with four semicircular arches. The bridge has undergone several rebuilds, with the end arches being rebuilt in 1770, the parapets widened in 1822, and new end walls built in the 19th century. It is a grade I listed structure.
When a new bridge was needed as the existing bridge was not wide enough to cope with traffic, Croxdale Bridge was constructed to the east of the existing bridge. The A1 at this point was later re-designated as the A167, and Croxdale Bridge continues to carry this road.
