A320 North of Woking improvements

Making improvements to the A320 in Runnymede between Chertsey and Ottershaw

Surrey County Council and Runnymede Borough Council have been awarded £41.8 million by Homes England's Housing Infrastructure Fund to improve the A320.

The works will ensure there is extra capacity on the busy stretch of road between Chertsey and Ottershaw to unlock future housing sites.

The works will make sure all the junctions and roads work well together to improve traffic flow. There will also be improvements for walkers and cyclists, including new crossing points and wider foot and cycle paths.

Upgrading the A320 could mean approximately 3,000 new homes can be built across ten sites in Runnymede – a key component of the borough's recently approved Local Plan. The largest site, Longcross Garden Village, could provide at least 1,700 homes.
