Lancaster Canal Carr Lane Bridge (That Part In Lancaster District)

Carr Lane Bridge, also known as Broken-Back Bridge, is a public road bridge over the Deep Cutting of the Lancaster Canal, which opened in 1797, likely designed by engineer John Rennie. The bridge is constructed of coursed squared sandstone and has a concave shape with slightly battered abutments. It features a semi-elliptical arch with a triple keystone. A band on the bridge indicates the original road level, which falls towards the center, creating the appearance that the arch has broken. The road surface has been raised, and the parapets, which have rounded copings and rectangular terminals, have been rebuilt. These parapets are pierced at the center with railings, likely to aid in draining the roadway. The bridge has been commonly referred to as Broken-Back Bridge for a long time, and this nickname has likely influenced the name of the lane it carries, originally known as Carr Lane. Part of this bridge is located in Thurnham civil parish.
