Construction continues on the 2.25-mile automated people mover (APM) service that will be the centrepiece of the Los Angeles International Airport (LAX) modernisation programme due to be completed ahead of the 2028 Olympics and Paralympics.
A portion of Airport Boulevard near LAX will be closed overnight this week for construction crews to place concrete for the APM's guideway, NBC Los Angeles reports.
The APM is a driverless, electric train system.
The APM system will have three stations inside the Central Terminal Area - which passengers can access through elevated pedestrian walkways from terminals - and three stations for passengers to access parking facilities, regional light rail transportation stations and the rent-a-car facility.
Officials say APM trains will arrive every two minutes and that passengers will be able to connect from the LA Metro to their terminal in 10 minutes or less.
The modernisation initiative, due to be completed in 2023, is a $14.3 billion (£10.1 billion/€11.8 billion) project that will improve all nine passenger terminals and build new facilities.
LAX figures to play a central role in facilitating the arrival and departure of athletes, officials and spectators when the Olympics and Paralympics take place in 2028.
