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.
Set to commence in February 2025, the scheme is schduled to be complete by winter 2026 and includes:
- New pedestrian crossings and cycleways
- Widening and resurfacing the existing road
- Installing new traffic signals
- Upgrading the road’s drainage system
