Background

The existing bridge was constructed in 1940 and is comprised of painted steel I-beams and concrete deck. The total length of the bridge is 37’ and the clear span is 30’. The overall width of the bridge is 28’ and carries two lanes of traffic on a 20’ wide paved roadway. There is a 4’ sidewalk on the east side of the bridge. An insulated utility pipe is installed on the exterior face of the upstream exterior girder, assumed to be a water main based on the presence of a fire hydrant on the same side of the road.
