Good progress on M25 works, National Highways says

Roadworks on the M25 in Surrey are “progressing well” as the motorway remains shut in both directions between junctions nine and 10, National Highways has said.

The M25’s weekend closure on Britain’s busiest motorway has been in place since Friday from 9pm while concrete beams for a new bridge are installed. It will reopen at 6am on Monday.

On Sunday in a post on X, formerly known as Twitter, National Highways said that “work is progressing well” and urged drivers to “please follow the official diversion routes to manage traffic flow effectively”.

Surrey Highways reported on Sunday at about 1.20pm that there were major delays in West Byfleet along Parvis Road and told drivers to try and avoid the area.

It also said there was congestion in Leatherhead, Oxshott and in surrounding areas of Weybridge, Cobham and Walton On Thames.

At around 3pm, it added that traffic levels were “reducing but the roads around the M25 closure and the diversions are still busy.”

Malden Rushett, Cobham, Esher and the A244 near Oxshott were still experiencing some delays.

Diversion routes take cars on a 19-mile journey on A roads, crossing from Surrey into London’s Ulez area, though National Highways has assured drivers “no enforcement action will be taken”.

However, the highways authority said anyone who ignores official diversion signs in an attempt to find shorter alternative routes will be liable for the £12.50 daily Ulez fee if their vehicle does not meet minimum emissions standards.

Failure to pay the charge when required can result in a £180 fine, reduced to £90 if paid within 14 days.

National Highways previously urged drivers to only travel the route if necessary, to avoid the closure and to complete their journeys in other ways if possible.

The M25 closure is the second of five planned weekend closures which come as part of a £317 million project to improve junction 10.
