National Highways have confirmed that the M25 will be shut between junctions 9 (A243 Leatherhead) and 10 (A3 Wisley) from 9pm Friday 10 May to 6am Monday 13 May 2024.
This full closure is needed to install a new bridge, with three other full weekend closures planned for later in 2024.
“We’re grateful to all drivers last time who avoided the closure and completed their journeys in other ways. We urge you to do the same again,” the organisation said.
A 19-mile diversion route will be in place which uses the A3 and the A240. Drivers are urged to follow the diversion and not SatNavs.
Clockwise diversion for all but over-height vehicles:
- leave M25 at junction 8, A217 (Reigate)
- follow the A217 London, Sutton, (A240) Kingston
- after 3½ miles turn left onto the A240 Epsom, Kingston
- after 3 miles at the Esso roundabout, turn right onto the A24 (A240) Kingston
- continue for 3 miles and at the Tolworth interchange turn left onto the A3 Portsmouth, Guildford
- continue for 9½ miles to the M25 and re-join the motorway at junction 10
Anticlockwise diversion for all but over-height vehicles:
- leave M25 at junction 10 to join the A3 towards London
- after 9½ miles at the Tolworth interchange leave the A3 turning right onto the A240 Epsom, Reigate
- continue for 3 miles to the Esso roundabout and turn left onto the A240 Reigate
- continue for 3 miles then turn right onto the A217 Reigate, M25
- after 3½ miles turn left to re-join the M25 motorway at junction 8.
Drivers using the signed diversion route won’t be subject to any Ultra Low Emission Zone (ULEZ) charges that may usually apply, although ULEZ restrictions will remain in force on all other routes in London across the weekend.
