The Los Angeles Board of Airport Commissioners (BOAC) has sanctioned the allocation of over $1bn to fund the final and largest construction phase for the modernisation of Los Angeles International Airport’s (LAX) Terminals 4 and 5.

With this approval, the Los Angeles World Airports (LAWA) can take over the renovated facilities from American Airlines, which is managing the ongoing work in both terminals.

According to the airport, the combined cost value of the projects stands at around $1.62bn.

American Airlines has decided to award around 20% of the work to local business entities for this project.

The terminal vertical core will feature new passenger check-in and baggage claim centres, a consolidated security screening checkpoint, a new post-security connection between Terminals 4 and 5 and a new headhouse area for passenger processing.

Furthermore, a pedestrian bridge linking Terminals 4 and 5 to the upcoming Automated People Mover train is being constructed.

The vertical core will also offer office and support spaces for the Transportation Security Administration (TSA), airlines and other law enforcement agencies.

It will be designed similar to the other cores that are under construction in the Central Terminal Area currently.

Terminal 4 will feature a new south concourse, which will include more space for hold rooms, restrooms, concessions and a bus gate.

For supporting US Customs and Border Protection Federal Inspection Station capability, the current two aircraft gates will be re-constructed.

In order to streamline the movement of the passengers, the north concourse will also be improved.

In a statement, LAX said: “Additional work includes improvements to Terminal 4 power systems, including transformers and backup power, replacement of the terminal’s aircraft apron and a reconfiguration of its hydrant fuelling system and underground utilities.

“These improvements are projected to be completed ahead of the 2028 Olympic Games, which will be hosted in Los Angeles.”

The upgrades sanctioned by BOAC will now be submitted to the Los Angeles City Council for approval.

Recently, the construction of LAX’s $2bn Consolidated Rent-A-Car (ConRAC) facility achieved a milestone after the structure was topped off by pouring concrete on its last 233,000 cubic yards.
