The Bulkeley Bridge (also known as Hartford Bridge, Bridge No. 980A) is the oldest of three highway bridges over the Connecticut River in Hartford, Connecticut. A stone arch bridge composed of nine spans, the bridge carries Interstate 84, U.S. Route 6 and U.S. Route 44 across the river, connecting Hartford to East Hartford. As of 2005 the bridge carried an average daily traffic of 142,500 cars.〔(''2005 Traffic Volumes State Maintained Highway Network (Traffic Log)'' ); State of Connecticut Department of Transportation p89.〕 The arches are mounted on stone piers, and vary in length from to ; the total length of the bridge is .〔(【引用サイトリンク】title=NRHP nomination for Bulkeley Bridge )〕 Completed in 1908,〔 the Bulkeley Bridge is the oldest bridge in the Hartford area and one of the oldest bridges still in use in the Interstate Highway System. It is also the largest and one of the last major stone arch bridges to be built in New England. Due to its historical, architectural and engineering significance, the Bulkeley Bridge was added to the National Register of Historic Places in 1993.〔 == History == The first substantial bridge across the Connecticut River at Hartford was the Hartford Toll Bridge, a two-lane covered bridge that opened in 1818. The span carried horse traffic, and in 1890 trolley lines were added, connecting Hartford to East Hartford and Glastonbury. On May 17, 1895, the bridge was destroyed in a fire. The flames started near the East Hartford end of the bridge, and within ten minutes had swept the entire tinder-dry structure. There had been much agitation for a new bridge, and the ''Hartford Courant'' reported a crowd of 20,000 spectators lined the banks of both sides of the river to watch the bridge burn. Backed by civic groups who saw an opportunity to create a monumental structure, construction on a permanent “Hartford Bridge” began in 1903. Hartford's civic and business leaders were determined that the new bridge would be "an ornament to the city which should endure forever." Designed by Edward Dwight Graves, the neo-classical stone arch bridge design that was selected in 1903 stood in contrast to the various truss bridge and suspension bridge in vogue at the time. To create a proper setting, the bridge commission tore down rows of tenements and constructed wide, landscaped approach boulevards on both sides of the river. The bridge opened on Oct. 6, 1908. At a total price tag of $3 million it was the most expensive bridge in the state, costing half-million dollars more than the Connecticut State Capitol building itself. Constructed from over of grey and pink granite, each ten-ton block was cut to remarkable tolerances of within a 3/8ths of an inch. When completed, the bridge connected two city streets: Morgan Street in Hartford and Hartford Avenue (now Connecticut Avenue) in East Hartford. After his death in 1922, the span was renamed for Senator Morgan Bulkeley. The former four-term mayor of Hartford had been instrumental in the bridge’s planning process. Bulkeley also served as Governor of Connecticut and United States Senator and was serving as the third president of Hartford-based Aetna Life Insurance Company. He was also elected to National Baseball Hall of Fame as the first president of the National League. As horse and buggy gave way to the automobile, the Bulkeley Bridge became the most important vehicular span in the state. Until 1942, the Bulkeley was the only motor vehicle bridge across the Connecticut River between Warehouse Point in East Windsor and Middletown. It handled a lot of cross-state traffic: US 5, US 6, and US 44, as well as earlier iterations of Connecticut Route 17 and Connecticut Route 101. Following a pair of horrific floods in 1936 and 1938 a series of levees were constructed along the banks of the Connecticut River, beginning Hartford’s retreat from the waterfront and partially obscuring views of 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「Bulkeley Bridge」の詳細全文を読む スポンサード リンク
