EAU Arvada Bridge

The EAU Arvada Bridge was a Parker through truss bridge located near Arvada, Wyoming, which carried Sheridan County Road CN3-38 across the Powder River. The bridge was built in 1917 by the Monarch Engineering Company of Denver. The single-span 8-panel bridge was 162 ft long and was connected by steel pins. When nominated to the National Register of Historic Places in 1982, it was one of only two Parker through truss bridges remaining in Wyoming.

The bridge was added to the National Register on February 22, 1985. It was one of several bridges added to the NRHP for its historic role in Wyoming bridge construction. The bridge was replaced in 1990.
