Located on the north side of Cavalier, this unique through girder bridge crosses the Tongue River.
Originally built in 1899, the main through girder of this bridge was moved here at an unknown date from an unknown location. The bridge features this through girder, approached by trestle on either side and sitting on timber substructures.
It is unknown where the span may have come from. Built by Keystone Bridge Company, the bridge still has two plaques intact. It is likely that it was moved here after the 1930s, although it is believed the date may be close to 1940. Oftentimes, the Great Northern, in addition to most other railroads, would move spans to save money. This girder replaced a small wooden truss bridge.
Keystone Bridge Company built at least two other spans for the Great Northern. It is also unknown if these are connected.
Overall, the bridge appears to be in fair to good condition, with no major deterioration noted.
The author has ranked this bridge as being locally significant, due to the common design.
