Great Northern Railway, Stone Arch Bridge/(Former) Navigation Channel, Minnesota, Minneapolis
The bridge was built by Minneapolis Union Railway to serve the Minneapolis Union Station. Known as the Stone Arch Bridge it was completed in 1883 and resembles a Roman viaduct. James Hill's, Great Northern Railway ran its tracks over the bridge. Originally, the bridge contained 23 limestone arches, measured 2,100 feet in length. In 1962, two arches were replaced by a steel Warren deck truss just below the Upper Lock and Dam to allow the passage of riverboat and barge traffic through the navigation channel. The Upper Lock and Dam was closed in 2015. In this photograph the former navigation channel had been lowered to allow for inspection of the channel, utility lines and related infrastructure. The bridge is located in the St. Anthony Falls Historic District listed on the National Register of Historic Places and is a contributing property. Also, it was designated a National Historic Civil Engineering Landmark.
