Bridge Documentation

This enormous concrete arch bridge is significant for its age and length, and was made famous in the Harry Potter movies. Constructed in 1901 it is an early concrete arch bridge, and its size would have made it a major engineering achievement in concrete construction at the time it was built. The concrete is unreinforced.
