Drivers have been warned of disruption after a section of the M25 was closed on Friday.
The closure of the motorway’s junction 10, near Wisley, and junction 11, near Woking, in both directions, is part of £317m improvement works to add extra lanes.
Disruption is set to last from Friday 21:00 GMT to 06:00 on Monday 10 March.
British Airways has urged passengers travelling to Gatwick or Heathrow to allow extra journey time.
National Highways urged drivers to avoid the closures and complete their journeys in other ways.
Drivers will also face closures on the same stretch of motorway from 21 March until 24 March.
Last year, National Highways closed part of the motorway three times for improvement works.
The infrastructure project began in 2022, but “extreme weather” has pushed back the expected completion date to spring 2026, said National Highways.
Some elements of the project have already been completed, including the new Wisley Lane and four gyratory bridges.
