LAX stated that the overhaul including the runway has not only been completed before time but also on budget.
The work involved the removal and replacement of the asphalt surface keel section of the existing runway, along with the replacement of concrete approach slabs at the Sepulveda Boulevard tunnel.
Furthermore, the runway was installed with new energy-efficient LED runway centreline lights.
The renovation project also covered the deployment of LED centreline lights at high-speed exit Taxiways H6 and H7, along with the replacement and repainting of asphalt pavement.
The asphalt work covered around 7,000 linear feet (lft) of the 11,095-foot runway.
Over 600 runway and taxiway lights were replaced in the overhaul project.
LAWA chief development officer Bernardo Gogna said: “Los Angeles World Airports (LAWA) is working constantly to find efficiencies in our modernisation and maintenance and the rapid rehabilitation of Runway 7R/25L shows our capability to work smarter while minimising impacts on airport operations.”
The project was executed in collaboration with the US Federal Aviation Administration (FAA).
The work, which was carried out by Sully-Miller Contracting, planned to take advantage of low traffic due to the Covid-19 pandemic.
To meet the deadline, the contractor worked in double ten-hour shifts and six days a week during the two-month runway closure period.
LAX stated that the new asphalt wearing surface is predicted to last for nearly a decade.
Runway 7R/25L, which is used for arriving flights normally, is the main arrival runway for the south airfield.
Last month, LAX added a new polymerase chain reaction (PCR) test to its Covid-19 testing options.
Developed by Visby, the new test provides the results in less than an hour.
