Langwathby Bridge over the River Eden

Langwathby Bridge: a metal Bailey bridge spanning the River Eden at Langwathby near Penrith in Cumbria.
The bridge was built in 1968 to replace an earlier sandstone one that was washed away in floods. The metal bridge was just meant to be a temporary measure and is now listed in the Guinness book of Records as the longest lasting temporary bridge in the country.
The Bailey bridge was designed by Sir Donald Bailey, and developed during World War II for military use.
