Final M25 weekend closure complete

National Highways has completed their final weekend closure of the M25

National Highways completed their final full weekend closure of the M25 over the weekend of 21 to 24 March. The road was reopened at 5.30am on Monday 24 March following the demolition of the second of the two old gyratory bridges.

This was the last time National Highways expect to close the M25 for an entire weekend for this project. Seven out of eight new bridges have been completed, there is just one more to build later in the summer.

We recognise that the closures associated with the Wisley interchange works have had a disproportionate impact on Surrey residents who need to use the surrounding roads on a regular basis. We want to thank residents for their patience and for changing their travel plans during the weekend closures.

The project is due for completion in spring 2026. It aims to reduce congestion, create a smoother flow of traffic and provide safer journeys for thousands of road users every day. More information can be found on the National Highways website.

A3 weekend closure

A full weekend closure of the A3 is planned for April. The closure will be in place in both directions between junction 10 and the Painshill roundabout/A245, from 9pm Friday the 11 April to 6am Monday 14 April. Diversion information can be found via the National Highways website.
