New bridge into RHS Wisley
A new dedicated bridge leading into RHS Garden Wisley is now open. The bridge is the first milestone to be completed as part of the National Highways project to upgrade junction 10 of the M25 and access to the A3.
New directions to the garden by car

If travelling by car, visitors who would normally access RHS Wisley from the A3 (onto Wisley Lane) will now use Ockham Park roundabout and follow new signage taking them onto the new bridge and over the A3 to the existing RHS Wisley entrance.
See more detailed directions below.
If you’d usually reach the garden travelling north on the A3 (from the direction of Guildford):
- Arrival: Option 1: Take the A3 up to junction 10 and briefly rejoin the A3 southbound to exit at Ockham Park roundabout to access the new road and bridge. Option 2: Leave the A3 at the earlier B2215 junction and follow Portsmouth Road (B2215) to Ockham Park roundabout and take the second exit to the new road and bridge.
- Departure: Option 1: Follow the new road and bridge to the Ockham Park roundabout and briefly take the A3 northbound up to junction 10 and then loop back to join the A3 southbound. Option 2: Follow the new road and bridge to the Ockham Park roundabout and take the B2215 to join the A3 at a later junction.
If you’d usually reach the garden travelling south on the A3 (from the direction of London):
- Arrival: Leave the A3 at the Ockham Park roundabout as normal and take the first left turning to the new road and bridge.
- Departure: Follow the new road and bridge and join the A3 at the Ockham Park roundabout.
If you live locally you may now be able to access RHS Wisley without travelling on the A3:
- If you are local to RHS Wisley and come from the direction of Horsley, Bookham or Leatherhead, you can come via Ockham using the B2039 and access RHS Wisley from the Ockham Park roundabout avoiding the A3.
- If you are local to RHS Wisley and come from the direction of Ripley, you can come via Portsmouth Road (B2215) and access RHS Wisley from the Ockham Park roundabout avoiding the A3.
- Access to the RHS Wisley via Pyrford Lock is unaffected.
We recommend that you check your sat nav or traffic apps before you travel.
Bus stops for RHS Garden Wisley
The bus stops on the A3 for RHS Wisley have now been removed. Our shuttle bus from Woking Station to RHS Wisley now stops at the post office bus stop in Ripley, where you can catch the 715 bus to Kingston and Guildford.
Please see our dedicated Getting to RHS Wisley page for more information about travelling to the garden by bus.
Questions and answers about M25/A3 works
Q: What is happening on the A3 and why?
A: National Highways is undertaking a scheme to improve road links at the M25 junction 10/A3 Wisley interchange which started in November 2022 following initial preparation works. The scheme is scheduled to complete in summer 2025. More information about the scheme and why it is happening can be found at the National Highways website.
If you have any questions about the scheme, please get in touch with National Highways on 0300 123 5000 or [email protected].
Q: How will it affect my visit to RHS Wisley?
A: RHS Garden Wisley will try to remain open as normal throughout and we look forward to welcoming you. The RHS is working closely with National Highways to minimise disruption to visitor journeys but at times you may need to allow a little extra time to complete your journey. We will update our website and social media to let you know, and you can find the latest updates on the National Highways website.
Q: How long will it take?
A: Work began in November 2022 and the scheme is scheduled to complete in summer 2025. For further updates on the progress of the works, please visit the National Highways website.
Q: Will RHS Wisley be closed during the work?
A: RHS Garden Wisley will try to remain open as normal throughout and we look forward to welcoming you. If the garden needs to close due to road closures we will update our website and social media to let you know.
Q: What can I do to support the RHS in opposing these plans?
A: Following the Secretary of State for Transport’s decision to grant final approval for the M25 Junction 10/A3 Wisley Interchange Development Consent Order in May 2022, work has now begun. The RHS and its supporters have done all we can to minimise negative impacts on the garden, and we are grateful to everyone who signed our petition and helped alter the original plans.
The RHS will continue to work closely with National Highways and other stakeholders throughout the project to provide regular updates and minimise disruption for those wishing to visit the garden. The RHS has also offered support and advice to National Highways with their plans to improve biodiversity in the wider area as part of the scheme. For the latest information, please visit the National Highways website.
Q: Will I get a discount on my membership/entry ticket?
A: No. RHS Garden Wisley will try to remain open throughout the works to the M25 junction 10/A3 interchange and both members and non-members will be able to visit the garden as normal. Every RHS Membership and ticket sold raises vital funds for our work as the UK’s gardening charity, and we are grateful for the continued support of our members and visitors.
Q: Are National Highways going to cut down trees in the garden/take land from RHS Wisley?
A: A section of former RHS land outside the garden is being used to create a new entrance along the A3 boundary and onto Wisley Lane as part of the approved plans. We are aware that some trees in this area will be felled to make way for the new overbridge.
We are reassured that National Highways has a robust environmental mitigation programme in place to restore heathland habitat and this will include extensive tree planting. For more information about this work please contact National Highways on 0300 123 5000 or [email protected] or see the National Highways Habitats factsheet.
Earlier proposals would have placed a number of important trees along our boundary with the A3 at risk, including several Grade II and Grade II* Heritage Trees, which were threatened by felling or compromising root health during the development. Thanks to our campaign, which saw more than 134,000 people sign a petition opposing the proposals, the scheme was altered and these important trees have been saved.
