Significance: The Duck Bridge is the oldest double-intersection Warren through truss in the state under Massachusetts Department of Public Works purview, and is one of the state's oldest all-riveted bridges. It was built by a significant late-nineteenth century bridge company, the Boston Bridge Works. The bridge is an integral part, both visually and historically, of the dramatic industrial landscape of the City of Lawrence, Massachusetts.
