The Pequonnock River Railroad Bridge is a railroad drawbridge (movable bridge) over the Pequonnock River in Bridgeport, Connecticut. Owned by the ]]The previous bridge was constructed in 1902 by the New York, New Haven and Hartford Railroad (replacing an earlier bridge) as one of two through girder Scherzer rolling bascule bridges on the New Haven Line. The bridge consisted of twin parallel rolling lift spans.[1]It was one of eight legacy moveable bridges on the Amtrak route through Connecticut surveyed in one multiple property study in 1986.[2] The eight bridges from west to east were: Mianus River Railroad Bridge at Cos Cob, built in 1904 (the surviving twin of the Pequonnock Bridge); Norwalk River Railroad Bridge at Norwalk, 1896; Saugatuck River Railroad Bridge at Westport, 1905; the Pequonnock Bridge; Housatonic River Railroad Bridge, at Devon, 1905; Connecticut River Railroad Bridge, Old Saybrook-Old Lyme, 1907; Niantic River Bridge, East Lyme-Waterford, 1907; and Thames River Bridge, Groton, built in 1919. The old bridge was added to the National Register of Historic Places in 1987, an honor not enjoyed for long, as it was obvious even before the survey that total replacement, rather than repair, was needed for the span. By the 1980s, the 1902 bridge had seriously deteriorated due to corrosion and metal fatigue. Compounding this was downstream movement of the main (pit) pier which supported the machinery and the waterproof chamber housing the descending component of the rolling lift spans; all of these issues forced a 10 mph restriction on all trains and closed the bridge to marine traffic. A new structure was designed with the same alignment utilized, but with improved track spirals to allow higher train speeds, and a bascule component which allowed a higher clearance and a wider channel for shipping.[3] In 1992, $80 million in federal funds were put aside to help replace the Pequonnock River railroad bridge by Rep. Christopher Shays, R-4th District and Rep. Rosa L. DeLauro, D-3rd District.[4]Construction work, which had begun as early as 1989, commenced at full speed by the mid-1990s with trains being diverted to a fixed shoofly bridge, and electrical utilities (United Illuminating as well as Metro-North) relocated to temporary structures. All work was completed in 1998. As on the old bridge, the movable span is twin parallel spans, capable of independent as well as tandem operation.==See also== *Connecticut Railway and Lighting Company Car Barn*History of Bridgeport, Connecticut*Thames River Bridge (Amtrak)==References==
