| 説明 | The Lake Pontchartrain Causeway, or the Causeway, consists of two parallel bridges crossing Lake Pontchartrain in southern Louisiana. The longer of the two bridges is either the longest or second-longest in the world depending on definitions, measuring at 23.87 miles (38.42 km) long. The Bang Na Expressway, a viaduct in Bangkok, is longer at 54 kilometres (33.55 mi), but is excluded from some lists of longest bridges because it crosses water for only a minimal portion of its length.The bridges are supported by 9,500 concrete pilings. The two bridges feature bascule spans over the navigation channel 8 miles (13 km) south of the north shore. The southern terminus of the Causeway is in Metairie, Louisiana, a suburb of New Orleans. The northern terminus is at Mandeville, Louisiana.The opening of the Causeway boosted the fortunes of small North Shore communities by reducing drive time into New Orleans by up to 50 minutes, bringing the North Shore into the New Orleans metropolitan area. Prior to the Causeway, residents of St. Tammany Parish had to go around the lake, either the east side via the Rigolets Bridge on U.S. Route 90 near Slidell, Louisiana or on the west side via U.S. Route 51 through Manchac, Louisiana.en.wikipedia.org/wiki/Lake_Ponchartrain_Causewayen.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_... |
