Los Angeles World Airports (LAWA) is full steam ahead on a major road and bridge reconfiguration project at LAX, and they’ve announced the first round of 31 intermittent road closures planned through 2030.
Starting next week on July 13, LAWA will impose temporary lane restrictions and full directional closures on Sepulveda Boulevard near LAX, for the construction of a new pedestrian bridge at the intersection of Century and Sepulveda boulevards.
The bridge is part of the broader Airfield and Terminal Modernization Program (ATMP) Roadway Improvements Project, a 4.4-mile road reconfiguration designed to separate airport-bound traffic from local neighborhood traffic, reduce congestion, and improve pedestrian and vehicle access to LAX’s Central Terminal Area (CTA).
First closure window: July 13–17, nights only
The first work period runs Monday, July 13 through Friday, July 17, from 10 p.m. to 6 a.m. each night. Crews will carry out intermittent traffic breaks on southbound Sepulveda Boulevard, with up to all four southbound lanes closed between midnight and 4 a.m.
Traffic may be halted for up to approximately 20 minutes at a time while structural beams are installed for the bridge’s falsework. Motorists should expect delays and build extra time into their trips.
Second closure window: July 18–19, full northbound shutdown
The second and more significant closure begins Saturday, July 18 at 1 a.m. and consists of a complete closure of northbound Sepulveda Boulevard between Century Boulevard and 98th Street. The closure is scheduled to lift by Sunday, July 19 at 4:30 a.m.
During that window, Los Angeles Department of Transportation (LADOT) traffic officers will be stationed at key intersections along designated detour routes, alongside flaggers to manage traffic flow. Los Angeles Airport Police will maintain routine patrols across LAX and the surrounding area.
31 more closures ahead
The July closures are only the beginning: officials have scheduled 31 additional intermittent closure periods as part of the same project for the next 4 years. LAWA expects the ingress roadway systems to be complete before the 2028 Summer Olympic and Paralympic Games, with the full egress roadway network finished by 2030.
To help travelers stay informed, LAWA has debuted a new website where you can get more closure information, work descriptions, maps, and detour routes.
