Los Angeles International Airport (LAX) in the US has commenced a $17.3m renovation of Runway 7R/25L and two taxiways of the airfield on the southern side.
During the overhaul work, the runway will be closed temporarily.
The scheduled work will be completed in about two months, with the runway expected to be reopened in May.
Overhaul work will consist of the removal and replacement of about 6,000ft of the runway’s asphalt surface in addition to Taxiways H6 and H7.
Moreover, the runway will see the installation of new energy-efficient LED runway centerline lights.
Los Angeles World Airports (LAWA) chief development officer Bernardo Gogna said: “At the start of the Covid-19 pandemic, we challenged ourselves to use this time of reduction in air traffic to complete repairs and airfield improvements more efficiently than ever before.
“The replacement of the asphalt on Runway 7R/25L is an example of how we are investing in the long-term health of our airport and completing work that would have been much more disruptive if done when we were operating at full capacity.”
The runway concrete approach slabs at the bridge over Sepulveda Boulevard will also be replaced.
The new LED lighting will reduce maintenance expenses and energy consumption..
The airport stated that the new wearing surface is projected to last for about ten years.
Construction engineering firm Sully-Miller Contracting Co is executing the overhaul work.
Runway 7R/25L, which is usually used for arriving flights, runs parallel to Runway 7L/25R.
Runway 7L/25R is located near the terminal buildings and usually handles departures. While some arrivals will be shifted to the north runway complex, Runway 7L/25R will be transformed for both departure and arrival use.
Last month, LAWA announced that it has completed a major airfield improvement project ahead of schedule by taking advantage of reduced traffic.
The project included the installation of new concrete on Taxilane C9, serving 12 gates at LAX.
The $2.85m project commenced late January after receiving approval from the board of airport commissioners.
