The ECR Kooi Bridge is a bridge in Sheridan County, Wyoming, located 2.7 miles (4.3 km) west of the community of Monarch. The bridge carries Sheridan County Road CN3-93 across the Tongue River. Contractor Jack Gregg built the bridge in 1913. The single-span pin-connected Pratt pony truss bridge is 81.6 feet (24.9 m) long with an 80-foot (24 m) span; it is the longest bridge of its type still in use in the Wyoming state and county highway system. The bridge's roadway was constructed with wooden stringers and decking; its guardrails are also wooden. The pin-connected Pratt pony truss was a common type of truss bridge in Wyoming, and the Kooi Bridge was one of the earlier bridges to use the design.^[2]

The bridge was added to the National Register of Historic Places in 1985.^[1] It was one of 31 Wyoming bridges added for their significance in the history of Wyoming bridge construction.^[2]
