Notes
- - Significance: The Upper Pacific Mills Bridge, built to carry workers and supplies to the mills, is one of only three or four known surviving examples of Thomas Moseley's wrought-iron tubular arch bridge. First built in 1855, Moseley's bridge designs evolved over a period of approximately twenty years and were the subject of several U.S. patents. Moseley is generally credited with introducing the riveted wrought-iron tubular arch to the American market. The "tubular" arch is actually a hollow triangle in cross-section, fabricated from iron boiler plate. The prominent counterarches, beneath the main arch of the bridge, were an attempt to prevent excessive deflection of the arch under asymmetrical deck loading. The Upper Pacific Mills Bridge was one of three tubular arch bridges that Moseley built at Lawrence. It is the oldest extant iron bridge in Massachusetts and one of the oldest riveted wrought-iron bridges in the United States. The bridge was rescued from demolition in 1989 and rehabilitated by students at Merrimack College, under the direction of Francis E. Griggs, Jr., Professor of Civil Engineering. The intent is to return the bridge to a site on the North Canal as a footbridge.
