The Moseley Wrought Iron Arch Bridge, also known as the Upper Pacific Mills Bridge, is a historic, riveted, wrought iron bridge now located in North Andover, Massachusetts. It is a National Historic Civil Engineering Landmark now listed on the National Register of Historic Places as the oldest iron bridge in Massachusetts, and one of the oldest such bridges in the United States. The bridge was completed in 1864 as Moseley Truss Bridge built by the Moseley Iron Building Works of Boston, to connect the Pacific Mills with Canal Street in Lawrence, Massachusetts by spanning the North Canal. It partially collapsed in the late 1980s, but was saved by removal to the Merrimack College campus, where it was renovated in the early 1990s for placement over a campus pond. It was rededicated in this new location on October 23, 1995. == References == * (Historic American Engineering Record (Library of Congress) ) * F. E.
