Significance: The Merrimac Bridge is located on a site which has been utilized as a major river crossing since the seventeenth century. It contains the oldest moveable span identified in the Massachusetts Department of Public Works database, and is still operable under hand power. It also contains one of the earliest riveted metal trusses identified in the state, which is one of the earliest known surviving works of the Boston Bridge Works, a nationally significant bridge-building firm in the late-nineteenth and early -twentieth centuries.
