It was built by Emil Prahl and Henry Sawtell, both of Miles City, to the standardized plans provided by the Montana Highway Department, a predecessor agency to the Montana Department of Transportation. It is a five-span continuous treated timber stringer bridge which is 95 feet (29 m) long and 20 feet (6.1 m) wide with a roadway width of 19 feet (5.8 m). Its ends are supported by timber abutments and wingwalls braced with wood pilings. The spans are between four sets of treated timber pile bents made of Douglas fir.[3]
