The bridge is supported on sandstone abutments and has a timber deck, 15 feet (4.6 m) in width.

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 feet (49 m) long and was connected by steel pins.

The EJP County Line Bridge is a Camelback pony truss bridge located near Hyattville, Wyoming, which carries Big Horn County Road CN9-60 across the Nowood River. The bridge was built in 1917 by the Monarch Engineering Company. As the bridge was originally thought to connect Big Horn and Washakie Counties, the two counties split the cost of the bridge, with each paying for one abutment and the two splitting the cost of the superstructure; this is the only recorded case of two Wyoming counties purchasing a bridge in such a way. Further surveys determined that the bridge is actually located entirely within Big Horn County. At 102 feet (31 m) long, the bridge is the longest Camelback truss bridge in Wyoming.
