Blackpool Bridge

A bridge mostly of limestone but with some admixture of sandstone in the mass of the masonry; all the features are of limestone. It spans about 16 m in one semicircular arch. Ashlar voussoirs about 60 cm deep. There is no keystone, but, at apex, the arch supports a short pilaster terminating in a raised section of coping with a ball. Plain flanking pilasters at each abutment. At each parapet end is a similarly raised section with a ball. The carriageway of the bridge is unusually wide, at about 5.5 m between parapets; the approaches rise gently to the centre.
