Description 

This bridge is significant as a representative example of the bridges constructed in the early 20th century. By the turn of the century with bridge design becoming standardized, the Warren and the Pratt trusses, with riveted construction, were widely used, replacing the variety of designs used in the 19th century. This bridge, with its extremely light members and narrow width, is typical of the town highway bridges constructed before the advent of substantial motor vehicle usage. This truss is also notable for its railing, a decorative holdover from the 19th century superceded by plainer pipe and angle railings soon after 1900. This bridge is eligible for inclusion in the National Register of Historic Places.
