Los Angeles International Airport (LAX) in the US has unveiled the $1.73bn West Gates at its Tom Bradley International Terminal.

The new gates were added as part of the airport’s $14.5bn modernisation project.

With five levels, the 750,000ft² facility will handle both international and domestic flights.

Depending on the aircraft’s size, the facility can offer 12 to 15 gates at nearly 1,700ft in length.

LAX stated that the construction on the new gates began in 2016 and was completed over the duration of four-and-a-half years.

The new gates feature comfortable seating options, touchscreen kiosks, wireless Internet and power points.

With the deployment of an automated storage and retrieval system (ASRS), LAX is said to have become the first US airport to use a technology associated with warehousing and distribution.

The West Gates include numerous passenger amenities such as two nursing rooms, a service animal relief area, art exhibitions, three children’s play areas and a quiet room.

In addition, the gates comprise a ramp tower that will serve along with the Federal Aviation Administration’s (FAA) control tower.

Los Angeles World Airports (LAWA) CEO Justin Erbacci said: “This is the first mega-project at LAX under the leadership and vision of Mayor Garcetti, working with our City Council and our Board to build a world-class airport, one that will redefine our airport experience.

“We are delivering fully modernised terminals, new technology and guest services and improved connections to our regional transportation system and investing in infrastructure that creates a more resilient airport and an even stronger economic engine for Los Angeles.”

A joint venture (JV) of PCL Construction and Turner Construction, in association with architects Corgan and Gensler, executed the project.

Under the project, improvements were also carried out at the new underground utility and more than 1.5 million square feet of new aircraft apron and taxiways/taxi lanes.

Earlier this month, LAX reopened Runway 7R/25L and two taxiways on the southern side of the airfield after finishing the $17.37m renovation project.
