The Dale Creek Crossing was a 650-foot (200 m) bridge in the southeastern Wyoming Territory, United States, completed in 1868. It was constructed by the Union Pacific Railroad as part of the first transcontinental railroad. With a maximum height of 150 feet (46 m) and with a necessity of cutting through solid rock on both sides, it was one of the most difficult parts of the line to build. The original bridge was built of wood, and its trestles began swaying in the wind from the opening day. The original bridge was replaced on the 1868 piers in 1876 by an iron bridge, manufactured by the American Bridge Company, and this was dismantled entirely in 1901 when the Union Pacific completed construction of a new alignment over Sherman Hill as part of a reconstruction project which shortened the Overland Route. This photograph of the Dale Creek Crossing was taken during construction in 1868 by the project's official photographer, Andrew J. Russell.Photograph credit: Andrew J.
