Interstate 10 (I-10), a major transcontinental Interstate Highway in the Southern United States, runs across the southern part of Louisiana for 274.42 miles (441.64 km)[1][3] from Texas to Mississippi. It passes through Lake Charles, Lafayette, and Baton Rouge, dips south of Lake Pontchartrain to serve the New Orleans metropolitan area, then crosses Lake Pontchartrain and leaves the state.
On August 29, 2005, the I-10 Twin Span Bridge was severely damaged by Hurricane Katrina, rendering it unusable. The bridge was repaired, and later replaced with two higher elevation spans in 2009 and 2010.
