Part of the M25 is set to close for a third full weekend next month.

The motorway between junctions 10 and 11 will shut from 9pm on Friday, July 12 until 6am on Monday, July 15.

This is to allow for the construction and installation of a bridge on the western gyratory of the roundabout at junction 10.

The new bridge will feature 68 beams, each weighing 16 tonnes, and another four beams weighing in at 40 tonnes.

National Highways senior project manager Jonathan Wade 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."

These improvements are part of an ongoing effort to make journeys safer and reduce pollution.

Identical work was carried out on the eastern gyratory of the roundabout at junction 10 during the May closure.

This is the third of five full weekend closures scheduled for the M25, with a further two due later this year.

National Highways and delivery partner Balfour Beatty Atkins are working with key stakeholders such as Surrey County Council, emergency services, local businesses, and Gatwick and Heathrow airports in preparation for the closure.

Residents, holiday-makers, concertgoers, and sports fans are being advised to plan their journeys in advance and make sure they allow extra time or seek alternative travel arrangements.

The official diversion routes for drivers going between junctions 10 and 11 will exit the M25 at J10 and follow the north bound A3 to the A245 Painshill junction, followed by the A245 towards Woking and Byfleet.

On reaching the Six Crossroads Roundabout, drivers will need to take the 5th exit to the A320 and continue until they reach M25 junction 11, where the diversion will end.

Further details about the closure and the project are available on the National Highways' website.
