Project information

You can view more details about the maintenance schemes taking place on the A2 below:

For safety during essential road repair work, we need to close the eastbound carriageway of the A2 between Brenley Corner and Wincheap.

The closure will be overnight to try to reduce disruption to traffic as much as possible. It will be Thursday 27 February to Sunday 30 March, Thursday to Sunday nights only, 8pm to 6am.

There will also be a daytime lane closure on the eastbound carriageway, 6am Friday to 8pm Sunday.

The diversion for eastbound motorway traffic will be via the A299 and A256, back onto the A256 Guston.

Eastbound traffic will leave the motorway at Brenley Corner, onto the A299 Thanet Way, then onto the A256 to Whitfield roundabout.

Work at the A2 Brenley Corner roundabout and slip roads will also be taking place, Monday to Wednesdays only, 3 March to 15 March.

Please remember that closures can change at short notice. You can check the latest information on our daily closures page or find live travel information on our Traffic England website. Our travel alerts give details of live incidents on our network.

We will be installing ice sensors in the westbound carriageway of the A2 at Lydden, Kent, as part of our weather station upgrade work.

Work

We need to fully replace the road surface on the bridge which carries the M25 over the M26. We will also re-waterproof the bridge and reapply a special surface treatment to improve vehicle grip through this 50mph section of the M25.

Closure

For safety, we’ll need to close the M25 junction 5 clockwise link road for 14-hours over two Saturday nights, with one lane remaining closed for up to a further two hours until midday on the Sundays.

The M25 will be closed clockwise at junction 5:

From 8pm on Saturday 15 March until 10am on Sunday 16 March 2025

Lane two will be reopened to traffic by 10am on Sunday 16 March.
Lane one will remain closed until midday.

From 8pm on Saturday 29 March until 10am on Sunday 30 March 2025

Lane one will be reopened to traffic by 10am on Sunday 30 March.
Lane two will remain closed until midday.

Travel through M25 junction 5 in the anti-clockwise direction won’t be affected.

Diversion

During these closures, between 8pm and 10am, there will be signed diversion routes in place:

M25 clockwise traffic will be diverted at M25 junction 3 to follow:

the M20 eastbound to junction 2
the A20 London Road southbound to the M26 junction 2a Wrotham Heath Interchange
and the M26 westbound towards M25 junction 5.

Traffic joining the M25 clockwise from junction 4 will be diverted via:

the A21 southbound and turned around at Morley’s Roundabout to return to M25 junction 5.

The A21 will remain open southbound for travel towards Sevenoaks. However, M25 traffic heading towards Surrey won’t be able to continue clockwise at junction 5 and will be directed to follow the signed diversion routes, above.

We’ve planned this work across two overnight shifts to minimise travel disruption and ensure one lane can be safely reopened by 10am each morning. However, we are expecting delays and recommend road users avoid the area until after midday, if possible, or allow extra journey time.

View diversion map.

Why do you need to keep a lane closed up until midday on Sundays?

There are several layers of asphalt under the road surface which have reached the end of their serviceable life. We’ll need to completely strip back the road surface so that these underlying asphalt and waterproofing layers can be replaced.

A longer period is typically needed for the materials to set in these circumstances.

Work

We're installing a new weather station alongside the northbound carriageway of the M4 junction 4a Heathrow Airport Spur Road.

This work is part of our ongoing efforts to replace weather stations across the network that are reaching the end of their serviceable life.

We’re returning to finish this work

We started this project in February and are returning to complete it.

Lanes 1 and 2 of the northbound Spur Road will be closed overnight, 10pm to 5am, from Thursday 20 March to Saturday 29 March, finishing at 5am on the Saturday.

Lane 3 will remain open northbound, so no diversion routes are needed.

More about the weather stations

These measure a large variety of different meteorological conditions, including air temperature, atmospheric pressure, rainfall, wind speed and direction, humidity, cloud height and visibility.

We use this information on overhead signs to warn road users of severe weather and road conditions. Replacing and upgrading these weather stations is an important step in improving the reliability of data collected. This helps National Highways, local councils, and other authorities to better plan for roadworks, closures, and emergencies.

We are carrying out essential bridge repairs to junction 12 of the M4 Theale Interchange.

Work includes replacing the expansion joints, waterproofing, and resurfacing to maintain the structural integrity to both bridges.

The hard shoulder of the M4 westbound carriageway under the bridge will be closed 24/7 for the duration of works.

Closures

Our works are nearing completion. We've been delayed due to cold weather and need one further closure to finish our works.
