Stephanie Sampson is the Director of Communications for LAX Development Projects (see for up-to-date details). To help remedy surface traffic congestion, Los Angeles World Airports (LAWA) is building a Landside Access Modernization Program (LAMP) at Los Angeles International Airport (LAX), the 2nd busiest airport in the US and  4th busiest in the world.
The Landside Access Modernization Program (LAMP) consists of 3 new terminal extensions in the airport, and 3 new facilities outside the airport near the 405 Freeway: a Consolidated Rent-A-Car Facility and a public parking structure with 405 Freeway access, and a Metro transit station at 96th Street & Aviation Blvd connecting to the LAX/Crenshaw and Green Lines. These will be connected by an Automated People Mover (APM) train system on a 2.25-mile elevated guideway.
By 2023, the APM will run 9 trains with 4 cars each, carrying up to 200 passengers and their luggage, with top speed of 47 MPH. During peak hours (9 AM to 11 PM), trains will be available at each station every 2 minutes, with 10 minutes total travel time end-to-end. Passengers will be able to view real-time flight information. Escalators & elevated walkways to and from the nearest APM stations will be in the terminals. (See map above, with the Airport on the left and the other facilities on the right.)
The APM will enable quick and convenient connections between the 405 or Metro and the airport for LA Metro, Rent-A-Car, and private parking structure users, eliminating shuttle trips to & from the terminal area. Several new roadways will be built through 2023, creating new access points. Parts of the new system will open in the next 2 years, and it will be ready for the LA Olympics in 2028. Additional roadway improvements near the airport, to alleviate traffic congestion, will begin in 2023 and be completed by 2035. (“It ain't over until it’s over!”) During the current construction, be sure to add extra time for travel to and from the airport.
