Questions and answers

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 starting in September 2022. Some preparation work will take place before then, and 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 Wisley?
A: RHS Garden Wisley will remain open as normal throughout and we look forward to welcoming you. There may be some periods during the works where you may need to allow a little extra time to complete your journey and we will update our website and social media to let you know. You can also look at the National Highways website.

Q: How long will it take?
A: Work will begin in September 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 Wisley be closed during the work?
A: No, RHS Garden Wisley will remain open as normal throughout and we look forward to welcoming you.  There may be some periods during the works where you may need to allow a little extra time to complete your journey and 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: On 12 May 2022, the Secretary of State for Transport granted final approval for the M25 Junction 10/A3 Wisley Interchange Development Consent Order. While the outcome is not the one we had long campaigned for, the RHS will not oppose the commencement of works. We will now liaise with National Highways and others to provide regular updates and minimise disruption for those wishing to visit the garden. 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 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 Wisley?
A: Earlier proposals would have placed a number of trees along our boundary with the A3 at risk, including several Grade II and Grade II* Heritage Trees, which were threatened by felling or undermining root strength during the development. Thanks to our campaign, which saw more than 134,000 people sign a petition opposing the proposals, the scheme was changed. The approved plans will not take any land that is part of the garden and just two trees on RHS land, which are not of horticultural significance, will be felled. To see full details of the scheme, please visit the National Highways website.
 
Q: Will this affect the building of the new Lake?
A: No. Construction of Clear Lake is scheduled to commence in early July 2022 and will not be affected by the works.
