The Frederick Douglass Memorial Bridge (also known as the South Capitol Street Bridge) is a swing bridge that carries South Capitol Street over the Anacostia River in Washington, D.C. It was built in 1950 and named after abolitionist Frederick Douglass. In 2007, the bridge was used by 77,000 daily commuters. The bridge connects at its southern terminus with Interstate 295 and the Suitland Parkway and thus provides access to downtown from those routes as well as from South Capitol Street and roads connecting to it. As a result, the bridge carries commuter traffic from Prince George's County, Maryland, and from Southern Maryland. The bridge is part of the National Highway System, as are South Capitol Street north of the bridge and the Suitland Parkway. The bridge provides a gateway to an industrial part of the city that the District of Columbia government wants to rejuvenate, including the area around the new Nationals Park for the Washington Nationals, which opened March 30, 2008. The bridge was re-decked in 1974 and again in 1988. In 2007, the bridge was closed from July 6 to August 29 for a $27 million renovation project meant to extend its life for 20 years. The northernmost portion of the bridge was lowered to become an at‑grade roadway with a new intersection at South Capitol Street and Potomac Avenue. Nearly three blocks of elevated roadway, which blocked access across South Capitol Street, were removed and replaced with at‑grade intersections that will help knit the neighborhood together. The deck was once again replaced and resurfaced, and new street lights and guard rails were added. ==Replacement bridge project== In late 2012, officials announced a $906 million plan to replace and realign the bridge. The project will build new interchanges between the bridge and Suitland Parkway, the bridge and Potomac Avenue SW, Suitland Parkway and Interstate 295, and Suitland Parkway and Martin Luther King, Jr. Avenue. The current four-lane bridge will be replaced with a $573.8 million six-lane bridge. A traffic circle with a large field (to be used for public gatherings, and suitable for several new memorials) will connect the north end of the bridge with Potomac Avenue SW. A second massive traffic oval on the south end of the bridge will help connect it to Martin Luther King, Jr. Avenue, and help expand the city's "monumental core" into Anacostia. Reconstruction of the two interchanges was estimated to cost $209.2 million. The remainder of the budgeted funds will help renovate New Jersey Avenue SE and turn South Capitol Street from an industrial corridor into an urban boulevard. The two-year project was to begin in 2013.〔(Halsey III, Ashley. "Decaying D.C. Bridge Reflects State of Thousands of Such Structures Nationwide." ''Washington Post.''

The CFA rejected the design in September, called it "uninspired". The agency asked for a design with a more "contemporary approach" and "bolder look".〔(Neibauer, Michael. "Four Teams Shortlisted for $608M D.C. Bridge Project." ''Washington Business Journal.'' January 30, 2014. ) Accessed 2014-01-30.〕 On January 29, 2014, the District of Columbia Department of Transportation (DDOT) announced the four construction teams that will be asked to solicit final bids on the bridge demolition and construction: * Frederick Douglass Bridge Partners (a joint venture of Tutor Perini, T.Y. Lin International Group, and Stantec) * Skanska Facchina (a joint venture of Skanska AB, Facchina Group, and Parsons Transportation) * South Capitol Constructors (a joint venture of Kiewit Corporation, Corman Construction, and URS Corporation) * South Capitol Bridge Builders (a joint venture of Archer Western Contractors, Granite Construction, and AECOM) The cost of the bridge (which included demolition and construction of the bridge and traffic ovals, but not the Suitland Parkway interchange) was now pegged at $608 million.〔 The new bridge will also require the removal of , which would be landlocked by construction of the new span. Mayor Muriel Bowser budgeted $512.7 million over six years, beginning in fiscal 2016, to begin building the bridge. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Frederick Douglass Memorial Bridge」の詳細全文を読む スポンサード リンク
