The Blacks Fork Bridge on County Road 221, north of Fort Bridger, or the Lincoln Highway Bridge, is structurally unsound and can’t be brought up to safety standards without being removed and replaced….
Julie Francis, WYDOT archeologist, said the bridge was a concrete T-girder bridge built in 1921 under Federal Aid Project 17. The bridge was typical of bridges built at that period. The bridge included two spans so it was 160 feet long and 18.4 feet wide. She said there were also 3.5 miles of Lincoln Highway roadwork completed as part of the same project. She said the construction of the present bridge replaced a timber trestle bridge.
