Part of the M25 will close next month near Cobham and Chertsey. National Highways is urging drivers to expect delays and to follow signposted routes as opposed to using sat-navs.
From 9pm on Friday, July 12, to 6am on Monday, July 15, it will be shut between junctions 10 and 11 to cater for the building and installation of a bridge on the western gyratory of the roundabout at junction 10.
The new bridge will consist of 68 beams – weighing 16 tonnes each – and another four beams weighing 40 tonnes. The previous closure in May saw similar work carried out on the eastern gyratory.
The upcoming works will be the third of five full weekend closures of the orbital motorway to happen, with a further two due later this year.

National Highways says that it and Balfour Beatty Atkins are working with emergency services, Surrey County Council, businesses and Gatwick and Heathrow Airports in the lead-up to the closure.
M25 diversion routes
Junction 10 to Junction 11: Leave the motorway at junction 10 and take the third exit to the northbound A3 to the A245 Painshill Junction, A245 towards Woking, and Byfleet. Then at the Six Crossroads Roundabout take the 5th exit to the A320 continuing to M25 junction 11 where the diversion will end.
Junction 11 to Junction 10: Exit the M25 at junction 11 and take the third exit to the A320 south towards Woking, then at the Six Crossroads Roundabout take the A245 towards Byfleet, continue on the A245 to the A3 Painshill junction. Then take the third exit to the southbound A3 to junction 10 where the diversion will end.
Jonathan Wade, National Highways senior project manager, said: “The previous two closures have gone well with significant progress being made during both.
“We would urge all drivers to follow the official diversion route as this is the best chance of reaching your destination in good time. Please ignore your satnavs and follow our diversion route instead.”
