Interstate 10 travels 274 miles across the state of Louisiana from the Sabine River and Orange, Texas to Sulphur, Lake Charles, Lafayette, Baton Rouge, New Orleans, Slidell and an exit across the Pearl River into Hancock County, Mississippi. The freeway is part of a transcontinental route between Santa Monica, California and Jacksonville, Florida. Between Baton Rouge and Slidell, Interstate 10 leaves an east-west trajectory for a 108-mile arc southward to Laplace, Kenner, Metairie and New Orleans. Interstate 12 stays north of Lakes Maurepas and Pontchartrain to provide the through route for long distance travelers.
Across the state, Interstate 10 sees several lengthy stretches of elevated roadway including the Acadian Thruway through Livingston Parish, the ten-mile viaduct between Interstate 55 at Laplace and Kenner, and the 5.5-mile Twin Bridges over Lake Pontchartrain.

Interstate 10 between Washington Street (Exit 156A) and Perkins Road (Exit 157A) in Baton Rouge was dedicated on September 18, 1964. A $4.38-million contract was fulfilled by Boh Brothers Construction Company, Inc. of New Orleans, with work commenced on September 24, 1962.2 Work continued through 1964 on the freeway east to College Drive (Exit 158) and 1965 to Interstate 12, and the first two miles of I-12 to U.S. 61 (Airline Highway).
A $24.3 million project began in the spring of 2006 to replace the aged concrete surface of Interstate 10 between Interstates 12 & 59 and the Twin Bridges through Slidell. The 6.65-mile project involved the rubblizing of the concrete road bed and the overlay of six inches of asphalt pavement. Completion occurred by November 2006.3
A $733-million project replaced the Hurricane Katrina damaged Twin Bridges over Lake Pontchartrain between June 2006 and September 2011. The new spans expanded the freeway from four to six overall lanes.

One third of the traffic along Interstate 10 between Lafayette and the Atchafalaya Basin Bridge is comprised of freight traffic. A $300 million, two-phase project, partially funded by a $60 million federal grant aimed to improved freight corridors, addresses capacity issues along this stretch. Beginning in 2017, expansion during the two-year long, first phase will add two lanes to I-10, between Interstate 49 (Exit 103) and Breaux Bridge (Exit 109), and from Henderson (Exit 115) east to the Atchafalaya Basin Bridge. The second phase, scheduled to start in the 2018-19 fiscal year, will six lane the intervening segment. Additionally the 1960s-built roadway will be rebuilt and Exit 115 with LA 347 will be converted to a dumbbell interchange.

|A historical look at Causeway Boulevard northbound at the directional cloverleaf interchange with Interstate 10. The interchange between Causeway Boulevard and Interstate 10 at Metairie is one of the most congested within the New Orleans metropolitan area. Therefore $86.6-million in road work was undertaken in April 2009 to address weaving traffic concerns. This work combined all movements to Interstate 10 from Causeway Boulevard north into a single ramp. The loop ramp to I-10 west is still present, but it is now accessed from a flyover ramp to the southeast. Photo taken 06/10/06.|
