ATMP Roadway Improvements Project
The ATMP Roadway Improvements Project is part of LAX’s Airfield & Terminal Modernization Project (ATMP) to help reduce airport-related congestion and traffic back-ups on surrounding public streets. As part of the ATMP Roadway Improvements Project, LAX is constructing 4.4 miles of replaced and reconfigured roadways to reduce congestion on Sepulveda Boulevard and create dedicated airport roadways for airport traffic queues headed to LAX’s Central Terminal Area (CTA).

Project FAQs
The ATMP Roadway Improvements Project is a major upgrade to LAX’s infrastructure, aimed at reducing traffic congestion and improving access to the Central Terminal Area. By building 4.4 miles of new and reconfigured roadways, elevated lanes, and pedestrian bridges, the project will separate airport traffic from local streets like Sepulveda Boulevard—removing over 500 vehicles from local roads at peak times. Construction begins in late 2025, with key elements ready before the 2028 Olympics and full completion by 2030.
