It is a reinforced concrete bridge with three spans. Its total length is 155 feet (47 m); the center span is 50 feet (15 m) and the two side spans are each 35 feet (11 m). It is 61 feet (19 m) wide and carries a two-lane roadway.[2]

It was designed by the engineering firm of Leonard and Day, whose senior partner, John B. Leonard " was perhaps the state's most important designer of concrete bridges in the first two decades of the last century."[2]

It was built by contractor C.H. Gildersleeve.[2]

It is structurally a concrete girder bridge although it has the picturesque appearance of a Luten arch bridge.
