Maintenance work on the A2

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

We’ll soon be returning to the A2 between Boughton-under-Blean and Upper Harbledown to carrying out essential repairs to the concrete that makes up the base layer of road.

This work is critical to maintaining and improving safety and should reduce the need for any unplanned closures.

We’ll carry out this work in two phases, starting on the London-bound carriageway on Thursday 16 May.  With all work progressing well, we’ll then plan to move to the coastbound carriageway from Thursday 11 July. Keep an eye on our webpage for more details as our work progresses

We’re coordinating with other works in the area to reduce the number of closures needed and minimise overall disruption.

Closure information

Thursday 16, Friday 17 & Sunday 19 May: we’ll be closing: the A2 London-bound from Wincheap to Brenley Corner, and the M2 London-bound from junction 7 (Brenley Corner) to junction 4 (Rainham) from 8pm to 6am each night. Brenley Corner Roundabout will be open.

Saturday 18 May: the A2 London-bound will be closed from Wincheap to Brenley Corner between 8pm and 6am. The M2 will be open.

A lane will remain closed on the A2 London-bound from Wincheap to Brenley Corner during the day from 6am Friday 17 May until our overnight closure starts at 8pm on Sunday 19 May.

From Thursday 23 May to Monday 24 June, we’ll be closing the A2 London-bound from Wincheap to Brenley Corner overnight from Thursday nights to Monday mornings between 8pm to 6am, with a lane closure in place during the day.

Please note, there are also overnight closures (Sundays to Fridays) on the London-bound M2 between junctions 7 and 5 until the end of May.

Diversion and access

During the closures, traffic coming from Dover heading towards London will be signed to join the M20. For local traffic a diversion will also be in place from the Whitfield roundabout via A256 and A299 Thanet Way to Brenley Corner. An escort will be provided for properties with direct access to the A2 within the closure, please approach the closure gate.

Update: we finished our first phase of closures at the end of March. We'll need more closures to complete these improvements and will provide details of these here once confirmed.

We’ll start on Monday 29 April, and will be carrying out the improvements under a mix of full closures, temporary traffic lights and lane closures. To minimise disruption, our full closures will take place on weeknights only when there are fewer vehicles on the road.

The work is currently scheduled to finish in November 2024 and while we always aim to work to the programme, unforeseen circumstances or adverse weather conditions may mean changes.

We’ll keep this page and our social media channels up to date with any changes, and will make every effort to ensure the impact on the local community and travelling public is kept to a minimum.

We won't need to close the M2 carriageway for this work.

We’re carrying out improvements to the drainage and safety barriers on the M2 between junctions 5 and 7.

As we need to remove the old barriers to complete our work, there are narrow lanes on the M2 to keep everyone on the motorway safe, with free recovery for anyone who gets into trouble.

We’ve started our work in the central reservation, and in late-April we’ll commence moving the narrow lanes to allow us to carry out improvements to the drainage and barriers on hard shoulder. To do this, we’ll need to close each carriageway for around twelve nights, see details below.

We’re due to complete our improvements in summer 2024, when the narrow lanes will be removed.

Maintenance work on the M25

You can find more details about the maintenance schemes taking place on the M25 below:

We recently switched off some sections of life-expired street lighting around the M25 network as part of our work towards achieving National Highways’ net zero targets.

This includes some sections of street lighting in the following areas:

  • 10.4 miles between junctions 6 and 9
  • 2 miles between junction 21a to 23
  • 4 miles between junction 29 to 30

Switching off these lights is estimated to save around 676,800 kgCO2e; the equivalent of taking over 400 cars off the road a year or the energy use of 85.3 homes over one year. Some areas, such as around junctions and slip roads, will remain lit and continue to be maintained. This will allow motorists to adjust between the different lighting levels on the M25 main carriageway and local road networks.

We carried out a thorough safety review prior to switching off the lighting in these sections. The lighting columns will remain in place for up to two years while we undertake further post switch-off safety reviews and signs are currently in place to indicate to motorists where sections of lighting have been switched off.

Our evidence on the M25 network suggests that turning off lighting reduces incidents. This not only supports the government's Net Zero strategy, but also benefits the environment, helping wildlife and reducing light pollution.

You can find more information about our net zero highways plan on our dedicated webpage.

Maintenance work on the M27

You can find more details about the maintenance schemes taking place on the M27 below:

Maintenance work on the M4

You can find more details about the maintenance schemes taking place on the M4 below:

We’re replacing expansion joints and renewing the waterproofing on the bridge which carries the M4 westbound over the Langley Interchange (junction 5) to keep journeys safe and reliable.

Scheduled closures and traffic management information

We typically work overnight between 10pm and 6am, however, we’ll require three longer overnight shifts to complete the first part of this work. To keep road users and our workforce safe, the M4 westbound carriageway at junction 5 is scheduled to close:

  • From 8pm on Saturday 8 June until 10am on Sunday 9 June
  • From 10pm on Monday 10 June for four nights until 5:30am on Friday 14 June
  • From 11pm on Friday 14 June until 6am on Saturday 15 June
  • From 10pm on Monday 17 June for four nights until 5:30am on Friday 21 June

Please remember that closure details can change at short notice. For the most up-to-date information, please visit our daily closures page.

Diversion

We’ll need to close the M4 westbound carriageway between the junction 5 slip roads. A short diversion route will be in place via the M4 junction 5 westbound exit slip road, onto the Langley Interchange roundabout and back on to the M4 westbound carriageway via the junction 5 entry slip road.

To reduce disruption, we’ll be using low noise emitting equipment where possible. We’ve also planned for the first three longer closures to take place overnight at weekends while traffic volumes are at their lowest.

 

We’re carrying out essential repairs to Welford viaduct, which takes the M4 over Rood Hill and the River Lambourn near Easton.

Works involve extensive concrete repairs, re-waterproofing, resurfacing, and replacing the bridge joint on both carriageways.

We've installed a 3-way temporary traffic light under the viaduct on Rood Hill. This will remain in place until we finish works.

Works are subject to change at short notice. Check the latest information on our daily closures page.

Closures

Thursday 14 June 2024 - M4 westbound junctions 13-14 overnight

The M4 westbound carriageway between junctions 13 and 14 will be closed from 8pm to 6am.

We’ve completed our contraflow switch. Traffic is now running on two lanes in each direction on the westbound carriageway, with a 40mph speed limit in place.

The eastbound carriageway is closed between junction 13 and 14, access for the emergency services will be retained on the eastbound carriageway.

When Rood Hill is closed, drivers will be diverted via A338, B4000 through Wickham and High Street.

When the motorway is closed, a fully signed diversion will be in place in both directions via A34, A4 Bath Road and A338.

 

We’re doing maintenance work on bridges carrying the M4.
