Congress Street Bridge (Connecticut) : ウィキペディア英語版 | Congress Street Bridge (Connecticut)
The Congress Street Bridge was a movable deck-girder Scherzer rolling-lift bridge in Bridgeport, Connecticut, United States. In 1909, the City of Bridgeport tasked a special commission to oversee the construction of a bridge at Congress Street. The original construction was completed in 1911 for $300,000. The bridge served as a street car, vehicle and passenger bridge throughout its service life. In 1997, the bridge was closed after the Connecticut Department of Transportation found the substructure to be moving. The bridge was demolished in 2010 and $40 million funding for a new bridge has since been secured. The Congress Street bridge was on the Connecticut Historical Commission's list of bridges. == History == In 1909, the City of Bridgeport created a special commission to oversee the construction of a bridge at Congress Street.〔 A local engineer, Raymond F. Stoddard was hired as design consultant and obtained the license to use the Scherzer design.〔 A Scherzer rolling-lift bridge with a double-leaf bascule was chosen for construction. The design is a Deck-type plate girder bridge; using two plate girders to support the deck. The Scherzer bascule was a popular design because it avoided the expense of high-stress pivot bearings; though it requires stronger foundations to support the weight of the bridge's operation.〔 The engineering firm, J. R. Worcester and Company designed and constructed the concrete-arch approach and Fort Pitt Bridge Works fabricated the movable bridge.〔 The cost of construction was $300,000, which was offset through funding from the Connecticut Company.〔 A contemporary account from the Hartford Courant gave stated the contract was for $305,000 to Snare, Tristo and Company. The bridge was opened to the public July 16, 1910. The Congress Street Bridge spanned the Pequonnock River and was designed to carry both street cars, vehicles and pedestrians across the river.〔 It was closed and left in the "open position" in 1997 when the Connecticut Department of Transportation found that the substructure was moving. With its closure, traffic has been diverted to the East Washington Avenue Bridge.〔 In 2002, the estimated cost to repair the bridge was $30 million, which could be partly funded by Connecticut's "Local Bridge Program".〔 A total of $5.8 million would be provided by the State of Connecticut with an additional $8.8 million loan.〔
