Interstate 59 (I-59) is a part of the Interstate Highway System that runs 445.23 miles (716.53 km) from Slidell, Louisiana, to just outside of Wildwood, Georgia. In the U.S. state of Louisiana, I-59 extends 11.48 miles (18.48 km) from its national southern terminus at I-10 and I-12 in Slidell to the Mississippi state line north of the town of Pearl River. This segment of I-59 is the shortest of the four states which it passes through.[5][6]

The route is located in the southeastern portion of the state, largely paralleling the older U.S. Route 11 (US 11) corridor for its entire length. All of I-59 in Louisiana is located in St. Tammany Parish. I-59 serves as a major thoroughfare through southeastern Louisiana, providing a fast route for travelers headed to and from New Orleans via I-10 and I-12. The Interstate is also an important hurricane evacuation route for travelers headed away from the warm Gulf Coast.
