Location: Ramsey, MI - Keystone Railroad Bridge

This is a one-arch railroad bridge over the Black River at Ramsay in Bessemer Township. This is a "keystone" bridge, where the keystone is the last stone set and ties the two other sections together, equalizing the pressure on all sides of the arch. The official designation of this bridge by the railroad is Bridge No. 11121. It is a 45 foot by 44 foot stone arch structure, 57 feet from the rail to flow line. The bridge was constructed in 1891 of limestone quarried at Kaukauna, WI at a cost of $48,322. The foundation of the bridge is on solid rock. [WAK-195-1009]
