M25 junction 10
Upgrading this stretch of road will provide vital improvements to its safety and reliability. At the same time, this scheme will involve some of the most extensive environmental mitigation ever carried out by Highways England, with over 40 hectares of land being used to replace the 14 that are needed to improve the junction.
Project information
Our proposed changes include building four new dedicated free-flowing slip lanes that will mean all left-turning traffic can pass through the junction unimpeded by traffic signals. Carriageways on the existing roundabout will also be elongated and widened to increase capacity for right-turning traffic.
On the M25 the hard shoulders through the junction will be converted to running lanes with emergency refuge areas.
We’ll also widen the A3 to four lanes in each direction between the Ockham Park junction and the Painshill junction, except where the A3 crosses over junction 10, which will stay as two lanes in both directions.
The changes would:
- reduce congestion
- smooth the flow of traffic to improve journey times
- support economic growth and new housing within the area
- improve safety
We aim to minimise the environmental impacts of the scheme and mitigate the impact the changes have.
