The Mid-Hudson Bridge (officially the Franklin Delano Roosevelt Mid-Hudson Bridge) is a toll suspension bridge which carries US 44 and NY 55 across the Hudson River between Poughkeepsie and Highland in the state of New York. Governor and local resident Franklin D. Roosevelt and his wife Eleanor attended the opening ceremony on August 25, 1930. The bridge was renamed the "Franklin D. Roosevelt Mid-Hudson Bridge" in 1994 though the span is rarely referred to by its official name. The bridge is long with a clearance of above the Hudson. At opening, it was the sixth-longest suspension bridge in the world. The chief engineer was Polish immigrant Ralph Modjeski, who had previously engineered the strengthening of the nearby Poughkeepsie Railroad bridge. Primary contractor was the American Bridge Company of Ambridge, Pennsylvania with steel from Carnegie. The span is unusual in that stiffening trusses were intentionally constructed on top of, not below, the deck. The toll for passenger vehicles is $1.50 (cash) and $1.25 (E-Z Pass) for eastbound traffic only. ==History== Proposals for the Mid-Hudson span were proposed by state legislature in 1923. At that time, there were no fixed crossing across the river south of Albany. The Bear Mountain Bridge in Westchester County and the Holland Tunnel in Manhattan were under construction at that time. Governor Alfred E. Smith signed the bill in June 1923. Construction would be undertaken by the New York State Department of Public Works (now the New York State Department of Transportation). Construction began in 1925. Caissons weighing 66,000 tons were sunk into the riverbed; dirt was removed by crews working in a pressurized environment. The Gothic steel towers were constructed in April 1929. Three years after opening, ownership was transferred to the New York State Bridge Authority in 1933, shortly after the Authority was created. The toll plaza was originally located on the eastern side of the bridge, but was moved to the western side in Ulster County when a new highway approach was opened in December 1967.〔(【引用サイトリンク】title=New York State Bridge Authority Mid Hudson Bridge Page )〕 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「Mid-Hudson Bridge」の詳細全文を読む スポンサード リンク
