Description 

This pair of bridges cross both the Pawcatuck River as a through truss bridge, and the White Rock Canal as a pony truss. The original configuration was unusual in that separate structures were provided for highway and trolley traffic with a common center truss. (See photo #2.) The highway portion was replaced after closing in 1976. (NBI says built 1996.) The railroad portion was retained for pedestrian use.
