As you are aware, National Highways is delivering the M25 Junction 10 upgrade scheme which is due to finish in the summer of 2025.
As part of this work, several bridges must be replaced over the M25 and A3 around junction 10. This requires closing the M25 and A3 at separate times.
The A3 will be closed in both directions between the M25 junction 10 Wisley Interchange and the B2215/A247 at Send to allow the safe installation of the beams for the new Cockcrow bridge.
The diversion route to go southbound during the closure will be via Cobham, Chessington, Great Bookham and Effingham, rejoining the A3 at Send.
To travel northbound the diversion route will be via East Clandon, Effingham, Fetcham and then onto the M25 towards Wisley.
