Recent improvements have already enhanced traffic flow through the implementation of jet lanes that bypass traffic signals. Additional upgrades include:
- New Wisley Lane opening
- New structures for pedestrians, cyclists, and horse riders
- Increased number of lanes for improved safety and traffic flow
Additional closure: The A3 will close in both directions between junction 10 and Cobham Roundabout/A245 from April 11-14.
Important notes for travelers:
- Plan extra travel time, especially for events at Twickenham and O2
- Main project completion expected summer 2025
- Final completion date extended to spring 2026 due to weather delays
- Most drivers won't experience significant disruption during the extended timeline
Jonathan Wade, National Highways' senior project manager, confirms these are the final closures and acknowledges that while some disruption is inevitable, the long-term benefits will justify the temporary inconvenience.
