Interstate 10 (I-10), a major transcontinental Interstate Highway in the Southern United States, runs across the southern part of Louisiana for .〔 It passes through Lake Charles, Lafayette, and Baton Rouge before dipping south of Lake Pontchartrain to serve the New Orleans metropolitan area before leaving the state. In August 2005, the I-10 Twin Span Bridge was severely damaged by Hurricane Katrina, rendering it unusable. Initially, the bridge was repaired through a $30.9 million contract with Boh Brothers Construction Company. However, Louisiana has since replaced the bridge with two higher elevation spans in 2009 and 2010. ==Route description== From Texas to Lafayette, I-10 parallels the older U.S. Route 90 corridor. From Lafayette, the highway heads east-northeast toward Baton Rouge via the Atchafalaya Swamp Freeway, an 18.2-mile (nearly 30 km) bridge across the Atchafalaya River and its accompanying swamp. Between the two cities, I-10 parallels U.S. Route 190, which runs from Opelousas to Baton Rouge. This route has signs and is designated as an alternate I-10 by-pass that runs from I-10/I-49 north to U.S. 190(exit 19B at Opelousas) then east across to Baton Rouge and back down to I-10 via I-110 south. Traffic can be diverted both ways along this route should there be the necessity to close I-10 across the Atchafalaya Swamp Freeway and is also used as a hurricane evacuation route. In the Capital City, U.S. 190 continues east alongside Interstate 12 to Hammond and Slidell while I-10 turns southeastward and parallels U.S. Route 61 (Airline Highway) to New Orleans. In the Crescent City, I-10 rejoins U.S. 90 (and later U.S. Route 11) as it heads toward Slidell. In Slidell, U.S. 11 continues northeastward toward Hattiesburg, Mississippi while I-10 and U.S. 90 turn eastward toward coastal Mississippi. Major bridges on I-10 in Louisiana include the Sabine River Bridge (c. 1952, replaced 2003), the Lake Charles I-10 Bridge (1952), the Atchafalaya Swamp Freeway (1973), the Horace Wilkinson Bridge over the Mississippi River (1968), the Bonnet Carré Spillway Bridge (c. 1972), the Industrial Canal Bridge (c. 1960), Frank Davis "Naturally N'Awlins" Memorial Bridge (1965, replaced 2010), and the Pearl River bridge (c. 1970). 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「Interstate 10 in Louisiana」の詳細全文を読む スポンサード リンク
