The First Hannibal Bridge was the first permanent rail crossing of the Missouri River[1] and helped establish the City of Kansas (renamed Kansas City, Missouri in 1889) as a major city and rail center. In its early days it was called the Kansas City Bridge.[2] It increased area train traffic, which contributed to the building of Union Depot, the predecessor to the Kansas City Union Station.[3] It was severely damaged by a tornado and replaced in virtually the same location by the Second Hannibal Bridge.

History

Construction started in 1867, shortly after the end of the American Civil War,[4] and was completed in 1869. The bridge was built for the Hannibal & St. Joseph Railroad by the Keystone Bridge Company.[4] The completion of the bridge came after a short battle between Leavenworth, Kansas, and the City of Kansas for the Hannibal & St. Joseph Railroad bridge.

The bridge was designed by Octave Chanute, who also designed the Kansas City Stockyards and later became a pioneer in aviation. After hearing of the proposed bridge at the City of Kansas, Joseph Tomlinson contacted Chanute and they corresponded on how best to cross the Missouri River. In October 1867, Chanute hired Tomlinson as the superintendent of superstructure.[5] George S. Morison, who later became a leading bridge designer in North America, apprenticed under the supervision of Tomlinson and Chanute during the construction of the bridge. It was a swing bridge that could open in under two minutes, and had an arched truss design. Construction cost Шаблон:US$ (equivalent to $Шаблон:Formatprice in Шаблон:Inflation-year).

In 1886, the bridge was severely damaged by a tornado that 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 Шаблон:Convert upstream on the northern bank, but at the same location on the southern bank where it enters into the gooseneck cut into the bluff.[6]
