The Carl E. Stotz Memorial Little League Bridge, formerly known as the Market Street Bridge, carries approximately 27,700 vehicles a day on U.S. Route 15 over the West Branch Susquehanna River between Williamsport and South Williamsport in Lycoming County, Pennsylvania in the United States. It is the seventh bridge on the site and was built at a cost of over $60,000,000. In October 2007 the new northbound bridge over the river and the new "direct connect" single-point urban interchange with Interstate 180 was completed and opened to traffic. The overall project, which included the reconstruction of Via Bella, was completed in summer 2008. ==History== The Carl E. Stotz Memorial Little League Bridge is the seventh bridge to span the West Branch Susquehanna River between Williamsport and South Williamsport at Market Street since the 1840s. It was built to replace the sixth Market Street Bridge, a steel deck structure which the Pennsylvania Department of Transportation originally intended to rehabilitate and widen. When this proved to be unfeasible, plans for a new bridge were put into place.〔(【引用サイトリンク】 Market Street Bridge: Project overview )〕 The first permanent bridge between was constructed beginning in 1844 and completed on July 5, 1849 (prior to its completion ferry boat service was available). This first Market Street Bridge, a wooden covered bridge, cost $23,797 to construct. It was owned by a private corporation, operated it as a toll bridge, and stood until March 17, 1865 when it was destroyed by a flood that left 90 percent of Williamsport underwater.〔(【引用サイトリンク】 Market Street Bridge History )〕 The second Market Street Bridge opened on December 1, 1865 and was a wire suspension bridge built for $58,068. The bridge was dismantled in 1886. It was also owned by a private corporation. The bridge, redesigned by Alfred P. Boller in 1886, was apparently a unique looking structure that caused some embarrassment to the owners.〔 The third Market Street Bridge was built in 1886 at a cost of $30,000 to $40,000. It was an iron truss bridge built by the Berlin Iron Company of Connecticut. It was partially destroyed by a flood on June 1, 1889, when the bridge was forced off its piers by timber that was swept down the river. This came from the Susquehanna Boom, part of the lumbering industry that helped make Williamsport one of the wealthiest cities in the world during the late 1800s.〔 The fourth Market Street Bridge was built upon the piers of the third bridge, using parts of the third truss bridge that had been swept downstream in 1889. The fourth bridge was opened in 1890 at a cost of $38,000, and was purchased in 1891 by the Lycoming County commissioners for $113,700, who declared to be free of tolls. Improvements to the bridge included raising it by 5 feet (1.5 m) and adding a sidewalk for pedestrian traffic. The fourth Market Street Bridge was destroyed by a flood on May 21, 1894.〔 The West Branch Susquehanna River was spanned by a fifth Market Street Bridge from 1894 until 1949. The two lane truss bridge was built by the Crofton Bridge and Manufacturing Company of Croton, New York. The bridge was nearly destroyed in 1909 when a discarded cigarette set a fire among the wooden planks of the bridge. Market Street Bridge number five was dynamited into the river and dismantled in 1949.〔 Market Street Bridge number six was a steel deck bridge. Construction was completed in 1951 at a cost of over $3,000,000. The sixth bridge was constructed by George Vang Inc. of Pittsburgh, Pennsylvania. It was dynamited and dismantled in 2007.〔 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「Carl E. Stotz Memorial Little League Bridge」の詳細全文を読む スポンサード リンク
