Junction 10 M25/A3.

Drivers that will be heading south towards Guildford on the A3 plan ahead due to an overnight closure on the A3 – M25 junction 10 scheme.

National Highways states in a press release that before the start of the scheme, some preparatory work needs to be carried out on the A3 southbound between the M25 junction 10 and Ockham Park. At the same time, the A3 southbound between the Burntcommon (A247) entry slip and the A3100 at Burpham will be closed for maintenance work.

The statement continues “The A3 southbound closure, between the M25 junction 10 and the A25 Dennis Roundabout (Guildford), will take place on weeknights between 10pm and 5.30am from Monday, August 22 to Thursday, August 25 and again between Tuesday, 30 August 30 to Friday, September 2 2022.

“Drivers travelling southbound need to plan ahead and will be diverted off the A3 using the M25 towards junction 9 for Leatherhead and follow the A24 and A25 to re-join at Cathedral Junction.

“Alternatively, non-motorway drivers will use the A245, Oakwood Road and the A244 to reach junction 9.”

This closure will not apply over the Bank Holiday weekend, Friday, August 26 to Monday 29  2022.

    What National Highways has failed to say is that their “offices” will be at Nuthatch Farm (site of the car boot sale). So all road work site traffic working on the west side (ie A3 north bound) will be coming into Burpham and back up the northbound slip. So there will be an increase in traffic during the works across Clay Lane Bridge and the right turn up the A3 as there is no alternative from this location. Bet no one thought that would happen!
