The Grand Tower Pipeline Bridge is a suspension bridge carrying a natural gas pipeline across the Mississippi River between Wittenberg, Missouri and Grand Tower, Illinois.[1]
Construction
Although construction of a natural gas pipeline under the Mississippi River would have been cheaper, this option would have created great difficulty in handling any leaks and maintenance, so it was decided to construct a bridge to carry the gas pipeline. The bridge was the first pipeline suspension bridge to cross the Mississippi River. It was constructed for the Texas–Illinois Natural Gas Pipeline company for an estimated $3,800,000 in 1953 (equivalent to $Шаблон:Formatprice in Шаблон:Inflation-yearШаблон:Inflation-fn). It was the final piece in the construction of a natural gas pipeline transporting gas from Corpus Christi, Texas to Chicago, Illinois, and Detroit, Michigan, which carries Шаблон:Convert of gas a day at a pressure of Шаблон:Convert. Work began in September, 1953. The bridge features two Шаблон:Convert steel framework towers, one on each side of the river. Vertical steel suspender cables connect the twin Шаблон:Convert pipelines to the main suspension cables, at a height of Шаблон:Convert above the river. During construction the Шаблон:Convert pipes were stretched out across the river where welders connected them together. Each pipe weighs 5 tons and it took 72 pipes to span the river, adding to around 360 tons of dead weight. The abutments to support this weight go to the bedrock, Шаблон:Convert deep on the Illinois side and Шаблон:Convert on the Missouri side. The site at Grand Tower/Wittenberg was chosen because the river is narrow and deep there, and the limestone bedrock could be easily reached.[2][3]
