The LaBranche Wetlands Bridge is a concrete trestle bridge in the U.S. state of Louisiana.〔(【引用サイトリンク】publisher=aaroads.com )〕 With a total length of 7,902 m or 25,925 ft, it is one of the longest bridges in the world.〔(【引用サイトリンク】publisher=The Times-Picayune )〕 The bridge carries Interstate 310 over the LaBranche Wetlands〔(【引用サイトリンク】publisher=saveourlake.org )〕〔(【引用サイトリンク】publisher=The Times-Picayune )〕 in St. Charles Parish. The bridge opened in 1992. The LaBranche Wetlands Bridge was constructed using a method known as "end-on construction" to avoid damaging the environmentally sensitive LaBranche Wetlands. This is a top-down technique in which construction platforms are mounted on concrete piles to avoid disrupting the environment below. From these platforms, the next set of piles and bridge viaducts are placed, allowing the platform to progress forward for the next set. The bridge won the 1992 Build America award in the Highway Division category.〔(【引用サイトリンク】publisher=kurumi.com )〕 ==See also==
