This bridge is a large, multi-span example of an uncommon truss bridge configuration, the double-intersection Warren truss. In addition, this bridge is an extremely old example of a truss bridge with riveted connections. It was built by Boston Bridge Works, a company that was a pioneer in using riveted connections in truss bridges. The bridge is located in an impressive spot that is surrounded by massive, historic textile mills and factories. This is truly a unique historical scene here. The Duck Bridge appears to retain good overall historic integrity. Original pedestrian railings remain on the bridge. There is an unusual bracing built over one of the sidewalks. HAER photos show an ugly windbreaker used to be attached to it, but the bracing appears to be old and may even be original and unrelated to this former windbreaker.'

The name Duck Bridge comes from a nearby mill that produced duck fabric.

This bridge is apparently slated for a rehab project.
