About the project
Funded by Homes England Housing Infrastructure Fund, GRAHAM is collaborating with Surrey County Council to upgrade the A320 in Runnymede, between Chertsey and Ottershaw. This project will significantly enhance four junctions and two road connections, facilitating the construction of new homes across Runnymede.
The upgrades will ensure that all junctions and roads work together to improve traffic flow. Additionally, there will be enhancements for pedestrians and cyclists, including new crossing points, wider footpaths and cycle paths, and better access to public transport.
The scheme commenced in February 2025 and includes:
- New pedestrian crossings and cycleways
- Widening and resurfacing the existing road
- Installing new traffic signals
- Upgrading the road’s drainage system
Latest Updates
We will soon be starting our work on the M25 Junction 11, where we will be building an additional lane on the M25 exit slips in both directions. The works are expected to take approximately 9 months to complete, and we will be working closely with National Highways in how best to co-ordinate our traffic management on these works. There will be periodic traffic management installed on the junction and full closures will be limited to off peak times where possible.
The works will increase traffic capacity and improve traffic flows, particularly at peak times, at the M25 junction 11. As part of these works, the final roundabout will be fully signalised.
M25 J11 Anticlockwise Exit Slip Closure
The first stage of traffic management to support these works will be a weekend closure of the M25 Anticlockwise Exit Slip at Junction 11. The road will be closed from 11pm Friday 02nd to 5am Monday 5th October, with a signed diversion route in place via:
• Continuing on the M25 anticlockwise carriageway
• Exiting at Junction 10
• Using Junction 10 to turn around
• Leaving the M25 clockwise at Junction 11
