The Farmington River Railroad Bridge is located north of the village center of Windsor, spanning the east-flowing Farmington River in a north–south direction, just north of Pleasant Street. It is a masonry structure 464 feet (141 m) long, built out of locally quarried sandstone, with seven arches mounted on piers and abutments of similar stone. The stone is formed into dressed rectangular blocks of varying sizes. The sides of the piers are articulated as pilasters, with a captstone set on a stone balustrade over each one.[2] The upstream sides of the piers have triangular projections to minimize damage caused by ice floes.
The bridge was built in 1867 by the Hartford and New Haven Railroad, and has carried the main line between Hartford and Springfield since then. This is particularly noteworthy, because the weight and force of modern trains is substantially greater than those at the time of its construction.[2] The bridge was designed to allow for the transit of barges beneath it on the river.
