Louis Armstrong New Orleans International Airport is about to put one of its two runways out of commission for most of 2026, and nearby residents are likely to hear the difference.
Starting March 2, 2026, the north-south Runway 2/20 will close for a major keel-rehabilitation and buildout project expected to last about eight months. During that stretch, all scheduled airline service will rely on the east-west Runway 11/29 while crews rebuild the runway core, upgrade lighting, and refresh surface markings. Airport officials say flight schedules should hold steady, but surrounding neighborhoods are being warned to expect new flight paths and more aircraft noise overhead.
What the work includes
The project calls for full-depth reconstruction of the two center keel panels along the entire 7,001-foot length of Runway 2/20. Crews will replace every in-pavement centerline light and can, reseal runway joints and lay down fresh markings.
Contractors will also demolish sections of abandoned airfield pavement and rebuild the approach lighting system that serves the east-west runway. The construction budget is listed at roughly $27.1 million, with completion targeted for December 2026, according to Louis Armstrong Airport.
Flight patterns and local impact
With work set to begin March 2, all arrivals and departures are scheduled to move to Runway 11/29 for the duration of the project. An airport spokesperson told reporters the temporary closure is not expected to disrupt airline operations or published flight schedules.
The catch is in the noise. Concentrating traffic on the east-west runway will likely shift and, in some areas, increase aircraft noise over parts of Kenner and nearby communities, as reported by WWLTV.
Funding and timeline
The work is being bankrolled primarily through the Federal Aviation Administration’s Airport Improvement Program. Federal grants are expected to cover roughly $22.5 million of the estimated $27.1 million construction tab. A release from U.S. Sen. Bill Cassidy's office highlighted the federal support for the runway reconstruction at MSY.
Airport officials say the closure of Runway 2/20 will last about eight months, with construction crews aiming to wrap up by December 2026, according to the federal funding announcement.
How travelers should prepare
For most passengers, the biggest change will be on the ground, not in the air. Travelers are advised to check with their airlines for any gate adjustments and to monitor real-time updates on potential delays while work is underway. The airport is also urging flyers to budget extra time for drop-offs, parking and security as the project progresses.
Pilots and operators can track official airfield changes and restrictions through the FAA NOTAM search. Passengers looking for broader project updates and any new guidance can follow the airport’s news page as the runway rehab moves forward.
