M25 closures: Junction 10 shut all weekend with no M25/A3 access

Roadworks on the M25 once again threaten chaos for travelling motorists this weekend, as National Highways implements a full closure of Junction 10 on London’s orbital motorway.

Drivers in Surrey will be unable to leave or join the M25 at junction 10 from 9pm on Friday (June 13) evening until 6am on Monday (June 16) morning. The same applies to those using the A3 as the junction for those wishing to join the M25 will also be closed in both directions. 

Both the M25 and A3 will remain open as usual for traffic passing through at junction 10 with only the entry and exit slip roads affected. Diversion routes will be signposted but heavy traffic along them is expected. Associated congestion is also likely to affect other routes close to the affected junction and the diversion routes.

The closure this weekend is the latest in a series that has included five total closures of the M25 in a project costing almost £320m. The works are designed to improve safety and travel times around junction 10 where the M25 motorway meets the A3. No further total closures of either the M25 or the A3 are currently planned. 

The work has involved numerous bridge demolitions, one of which is being replaced with a thoroughfare billed as the UK’s first ‘heathland bridge’ which will be planted to accommodate wildlife as well as pedestrians.
