Twizel Bridge
Built 1511 by Christopher Scune[1]
A Grade 1 listed medieval single-arch masonry bridge crossing the River Till, upstream of Twizel Castle in Duddo, Northumberland, near the England-Scotland border.
With a span of 90 feet, it is believed to be the largest single-arched medieval bridge in England. It was the widest single-span bridge in the country until 1727, when the Causey Arch in County Durham was built.
The bridge was in use for vehicles until 1983 when it was bypassed by a modern bridge. The parapets are thought to have been rebuilt in the 19th century. During the 1980s the southern parapet at the west end was continued across the bridge to obstruct any vehicle traffic. It is 4m wide between parapets. At the north east end of the bridge the wing walls turn eastward, and the road is thought to have been realigned. At some point in its history a tunnel was made through the eastern abutment. The building of the bridge is traditionally attributed to the Selby family. It is thought to have been used by English troops on the way to the Battle of Flodden in 1513. Strengthening was carried out in 1977.[2]
