The First Hannibal Bridge was the first bridge to cross the Missouri River and was to establish Kansas City, Missouri as a major city and rail center. Construction started in 1867, shortly after the end of the American Civil War.〔O. Chanute and George Morison, ''The Kansas City Bridge with an account of the Regimen of the Missouri River and a Description of the Methods used for Founding at the River'', D. Van Nostrand, NY, 1870, Michigan Historical Reprint Series, University of Michigan〕 Construction on the bridge was completed in 1869. The completion of the bridge came after a short battle between Leavenworth, Kansas and the town of Kansas City for the Hannibal & St. Joseph Railroad bridge. After construction was completed, the population of Kansas City began to boom. It was designed by Octave Chanute, who also designed the Kansas City Stockyards. It was a swing bridge which could open in under two minutes, and it had an arched truss design. The bridge cost $1 million to build in its day. The bridge was built for the Hannibal & St. Joseph Railroad by Keystone Bridge Company. Although the railroad became part of the BNSF Railway, the name "Hannibal" has stuck. In 1886, the bridge was severely damaged by a tornado which collapsed a middle span. It was reconstructed and its truss structure was altered from an arch design to a traditional truss design. It was later replaced by the Second Hannibal Bridge 200 feet upstream on the northern bank, but at the same location on the southern bank where it enters into the gooseneck cut into the bluff,〔http://www.kchistory.org/cdm4/item_viewer.php?CISOROOT=/Maps&CISOPTR=1525&CISOBOX=1&REC=1〕〔http://www.kchistory.org/cdm4/item_viewer.php?CISOROOT=/Maps&CISOPTR=1526&CISOBOX=1&REC=1〕 where it still stands today. ==See also== *List of crossings of the Missouri River 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「Hannibal Bridge」の詳細全文を読む スポンサード リンク
