The Conservation of Bats in Bridges (COBIB) Project was set up in June 1996 to carry out a bat survey of bridges in Cumbria, to liaise with bridge owners and managers over bat conservation, and to promote the conservation of bats in bridges. 2,555 bridges were surveyed during the project. 320 (12.5%) were confirmed as bat roosts, and 1039 (41%) had suitable crevices but no proven roost.
