}} The Albert Gallatin Memorial Bridge (also known as the Point Marion Bridge〔) was a cantilever truss bridge that carried vehicular traffic across the Monongahela River in the southwestern part of the U.S. state of Pennsylvania. Built in 1930 to replace a ferry, it connected Point Marion in Fayette County and Dunkard Township in Greene County. It was named in honor of U.S. Senator, and longtime U.S. Treasury Secretary and diplomat Albert Gallatin, whose Friendship Hill homestead is nearby. ==History== The original bridge was constructed in 1930 by the Point Marion Bridge Company and rehabilitated in 1976.〔(【引用サイトリンク】title=Point Marion Bridge - ''Albert Gallatin Memorial Bridge'' )〕 It was a historically significant bridge due to the relatively unusual cantilever truss design and was listed on the National Register of Historic Places as the second oldest bridge of this type in the state.〔(【引用サイトリンク】title=Canary Systems - Project Profile – Bridge Abutment Construction Monitoring )〕 It was replaced by the new Point Marion Bridge in October 2009. The old bridge was imploded on November 16, 2009. 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「Albert Gallatin Memorial Bridge」の詳細全文を読む スポンサード リンク
