Los Angeles World Airports (LAWA) has completed the relocation of power lines ahead of schedule to support the expansion work at Los Angeles International Airport.

The Scattergood No 2 project was carried out along with the LA Department of Water & Power (LADWP).

Work included tunnelling under a 108in storm drain to relocate the LADWP Scattergood transmission lines along Aviation Boulevard.

The work is expected to aid the 98th Street project, under which 98th Street will be extended to the 405 freeway from its current endpoint at Bellanca Avenue.

LAWA, which owns and operates Los Angeles International Airport and Van Nuys Airport, completed the project three weeks before the scheduled date.

LAWA stated that the project was finished within budget and did not report any safety incidents.

The 98th Street project involves moving a 10in gas line, a 48in perpendicular tunnel and communication lines.

In addition, a 30in gas line will be relocated in the second quarter of next year.

LAWA LAMP and Utilities Enabling Project (LULEP) project manager Dan McKelvie said: “We are proud to have finished this project ahead of schedule, within budget and with no safety incidents. This project completion is another step on the path to creating a world-class vision for LAX.”

The modernisation programme at LAX includes the construction of a 2.25-mile elevated Automated People Mover train system, with three stations in the Central Terminal Area (CTA) and three outside the area.

A consolidated car rental facility and other roadway improvements are also part of the project.

In March, LAX Integrated Express Solutions (LINXS) broke ground on the $4.9bn automated people mover (APM) project.
