M25 to be fully closed again for bridge works

National Highways has confirmed the M25 will be subject to another weekend closure for the construction and installation of a bridge.

The motorway will be closed between junctions 10 and 11 from 9pm on Friday (July 12), to 6am on Monday (July 15), for the bridge works.

The new bridge, consisting of 68 beams, each weighing 16 tonnes, and another four beams weighing 40 tonnes, will be installed as part of ongoing work to make journeys safer and reduce pollution.

The previous closure in May saw identical work being carried out on the eastern gyratory.

Drivers are again being warned to expect delays and only travel if necessary.

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.”

It is the third of five full weekend closures of the M25 to take place with a further two due later this year.

National Highways and delivery partner Balfour Beatty Atkins are working with key stakeholders in the lead up to this closure, including emergency services, Surrey County Council, local businesses and Gatwick and Heathrow Airports. 

RAC Breakdown spokesperson Alice Simpson said: “With most drivers following the official advice, major congestion was averted during previous M25 closures and there’s no reason why the same can’t happen this time.

“Drivers should follow the signed diversion routes which have been designed to keep traffic flowing as much as possible.”

She added: “It’s worth remembering that the closure coincides with the finals at Wimbledon, so anyone planning on driving to this should anticipate a far longer journey or look at whether there’s a viable public transport alterative.”

Diversion routes
