M25 junction 10 road closures and heathland restoration

A National Highways scheme making improvements

National Highways is making significant safety improvements at junction 10. The improvements aim to reduce congestion, create a smoother flow of traffic and provide safer journeys for thousands every day.

Road closures in 2024

There will be a series of weekend road closures on both the M25 and A3 in 2024 to facilitate National Highways work. The road closures are expected to cause traffic and travel disruption in areas of Surrey. To keep up to date and find out when closures are coming, visit National Highways M25 junction 10 project website.

Why are road closures needed?

As part of the ongoing improvements, National Highways is building a new bridge for drivers, walkers, cyclists, and horse riders across the A3 onto Wisley Lane. The Wisley Lane bridge needs replacing as it'll create new and safer access for vehicles to Wisley Lane and RHS Wisley from the A3. The closures are needed for this work to continue.

Who can I contact about the works?

If you have questions about the project, you can contact National Highways by emailing info@nationalhighways.co.uk or calling 0300 123 5000.

Restoring heathland around junction 10

As part of National Highways improvements large areas of heathland across Wisley and Ockham Commons are being restored. Junction 10 is surrounded by ancient heathland – a rare habitat that has declined in Surrey by 85% over the last 200 years. Left on its own, heathland quickly grows into dense woodland and the animals and plants that depend on it disappear.

The work here involves the removal of some trees to allow the heathland to regenerate.

Why are trees being cut down?

Tree removal is the first step to getting the land back to its natural state. A lot of the heathland in this area was lost when non-native trees were planted here for timber after the Second World War.

To make use of the wood, National Highways has been helping local businesses, construction companies and charities to recycle the overgrown Scots Pine into useful things such as fencing, tables, chairs, firewood, horse bedding and much more.

The tree removal will encourage regrowth and increase the variation of height and age of trees. New areas of native tree and shrub species, which are best suited to the conditions here, will also be planted along and around the roads. Woodland clearance around parts of Ockham Common is ongoing. This is a long-term process and includes thinning over-grown woodland.
