This undated drawing by the engineering firm of Gurley & Company of Troy, New York, depicts a plan of the first iron bridge built over the Connecticut River between Sunderland and Deerfield, Massachusetts. Built in 1877, after hurricane-force winds had caused the previous bridge to collapse, it was the seventh structure to occupy the location. Because previous bridges had been owned and operated by a private company, pedestrians and other traffic paid a toll to cross the river. The new bridge, paid for and maintained by the towns of Sunderland, Deerfield, and Whately required no tolls.
