The bridge is a riveted Pratt deck truss bridge constructed in 1928. It has three main spans upon reinforced concrete abutments and piers. The bridge is 421 feet (128 m) long in total, with four 19 feet (5.8 m) approach spans, two 77 feet (23 m) deck truss spans, and a 191 feet (58 m) deck truss main span. It is 25 feet (7.6 m) wide, supporting a 24 feet (7.3 m) roadway.[2]

This Pratt deck truss design is visually pleasing and rare. It was chosen by state staff for relatively rare circumstances during 1928 to 1932, after which a version of a Warren truss design was used.[2]
