Work to improve signage for customers, providing a more efficient reminder that DartCharge payments are due.

We’re carrying out work to repair defects in the carriageway and resurface the A2 carriageway at Boughton.

To allow us to carry out these works safely and to allow time for materials to cure, the A2 will be closed between junction 7 of the M2 (Boughton) and A28 at Canterbury (Wincheap), over the following weekends:

London-bound (westbound) carriageway:

  • 8pm on Friday 11 June through to 6am on Monday 14 June 2021
  • 8pm on Friday 25 June through to 6am on Monday 28 June 2021

Coast-bound (eastbound) carriageway:

  • 8pm on Friday 18 June through to 6am on Monday 21 June 2021

Clearly signed diversions will be in place:

  • Eastbound - Leave the M2 at junction 7, diverted traffic will follow A299, A256 to re-join the A2 at Guston
  • Westbound - Leave the A2 at Guston, diverted traffic will follow the A256, A299 to re-join the A2 at junction 7 of M2

A2 Boughton to Dunkirk Diversion Route Map

We’re carrying out work to improve the embankment’s stability along the A21 from Seven Oaks bypass at Westerham Road to Morley’s Roundabout on the southbound carriageway

This will involve installing soil nails to the slope and carrying out some vegetation clearance, replacement fencing, installing new drainage and planting new vegetation.

This work will means we’ll need to reduce the A21 from the Sevenoaks bypass at Westerham Road to Morley’s roundabout down to one open lane with a 50mph speed limit during the day and night for the duration of the works.  There will be free recovery in place.

The A21 carriageway from Seven Oaks bypass at Westerham Road to Morleys roundabout will be closed overnight on Sunday 11 April 2021 from 8pm until 6am the next day. This is so we can remove the current single lane traffic system with 50mph back to normal.

Diversion route

At the A25 junction, southbound traffic will be diverted off the A21 and onto the A25 Westerham Road eastbound. At Riverhead, traffic will be diverted south onto A224 London Road and onto A225 Tonbridge to Morleys roundabout.

A21 Kippington to Dibden Lane diversion

There will also be further overnight closures for:

  • positioning plant and equipment
  • removing traffic management

We will provide further details nearer to the time for these works.

Read our A21 Kippington to Dibden Lane newsletter.

We’re carrying out expansion joint replacement, to A27 Holmbush Slip Road, signed A270 Southwick/Shoreham which spans over the A27.

Main works

To allow us to carry out the works safely we will need to  fully close the slip road for two weekends in May 2021. We will have a contingency weekend in case of adverse weather or for operational reasons.

Weekend closures

The A27 Holmbush Slip Road will be closed from Friday 21 May at 9pm until Monday 24 May, 6am.

Diversion

Traffic will be diverted via A27, A293 and A270 back to Holmbush roundabout.

We're carrying out work to replace the expansion joints on the Coldharbour Lane bridge which spans the M20.  Prior to this work, we'll also be carrying out some resurfacing work. 

This work means we must close either side of the bridge for a full weekend each. 

Full Closure East Side

Friday 11 June 2021, 8.00pm to Monday 14 June 2021, 6.00am

Full Closure West Side

Friday 18 June 2021, 8.00pm to Monday 21 June 2021, 6.00am

We have also booked Friday 25 June 2021 to Monday 28 June 2021 but only on a contingency basis.

During the closures, we will have diversions in place which will add approximately 10 minutes to journey times.

Traffic wishing to join the eastbound carriageway at M20 junction 5 will be diverted down to junction 4 to join the eastbound carriageway. 

M20 eastbound traffic will be diverted up to junction 6 to turn around, re-join M20 to exit at junction 5

Traffic wishing to join the westbound carriageway at junction 5 will be diverted up to junction 6 to join the westbound carriageway. 

M20 westbound traffic will be diverted down to junction 4 to turn around, re-join M20 to exit at junction 5. 

Before this work, we'll also be closing both bridge decks for resurfacing on Wednesday 9 June and Thursday 10 June from 8.00pm until 6.00am.  

As is always the case, our work is subject to change due to weather conditions or unforeseen circumstances.  During these works emergency services will not be able to cross the bridge decks when they are fully closed and will need to follow the diversion routes instead. The access around the rest of the roundabout will remain but the bridge will not be able to be crossed. Access will remain in place to the Coldharbour depot side of the roundabout for entry to and from the depot and also for affected local residents.

We're carrying out essential maintenance work to the revetment wall which is in a poor state due to corrosion. If the revetment isn’t maintained, it will not provide protection to the bund and will cause damage to the cycle path.

For everyone’s safety, we'll be closing the cycle route/footpath along the top of the revetment for 24 hours daily for the duration of the work. A signed diversion will be in place via the A27 Bedhampton roundabout, Havant Road and the A2030 Eastern Road.

Between spring and autumn 2021, a series of maintenance work takes place along the A31, between Cadnam in Hampshire and Bere Regis in Dorset.

We will be combining various activities under several overnight closures. By combining work, we aim to keep disruption to both road users and local communities to a minimum.

Work will include resurfacing, safety barrier replacement, road marking renewals, and replacement of street lighting and road signs.

All work will take place overnight, between 9pm and 6am. At present, the following closures have been scheduled:

Tuesday 1 June for six nights

Closure of the A31 eastbound and westbound carriageways between Bere Regis and Sturminster Marshall (Roundhouse roundabout).

Diversion via the A35 and A350.

We’d also encourage drivers to stick to speed limits and follow appropriate signage to ensure the safety of those working on site and fellow road users.

We’re replacing the cattle grid, located off the A31 westbound carriageway at the Picket Post Services/Burley junction.

The entire cattle grid has been deteriorating over time, and despite numerous repairs to make it safe, inspections have found that the best solution is to replace it completely.

The link between the Picket Post services roundabout and Picket Plain Common Road will be fully closed from 10am on Monday 24 May through to 5am on Tuesday 22 June 2021.

Drivers wishing to exit the A31 westbound and head towards Burley, will need to continue west along the A31 to the Poulner Hill junction (just before Ringwood), exit at the junction turn right and head over the bridge, turn right again and join the A31 eastbound carriageway. The exit the A31 at Picket Post services and follow signs for Burley.

Drivers wishing to join the A31 westbound, will need to head under the bridge and join the A31 eastbound carriageway. Continue along the A31 then exit at the roundabout for Cadnam/M27 junction 1, circumnavigate the roundabout and join the A31 westbound carriageway.

We are replacing the waterproofing material within the surface of the bridge, which carries the A33 southbound link over the River Itchen near Kings Worthy.

A lane closure will be in place on the A33 southbound link with a speed limit of 40mph.

The A33 southbound link (between Kings Worthy and the A34) will be closed overnight on the following dates to set up, amend and remove the traffic management:

  • Saturday 15 and Sunday 16 May 2021
  • Saturday 19 and Sunday 20 June 2021
  • Saturday 3 and Sunday 4 July 2021

The project will not require any closures of the A34.

We will do our very best to complete the work as quickly as possible, keeping disturbances and noise to a minimum.

For information on road closures, visit our Travel Updates page.

Diversions

Standard vehicles (e.g. under 7.5tonne) will be diverted from the A33 at Kings Worthy via the B3047 towards Alresford, then onto the A31 and Spitfire Link to return access M3 junction 9.
Heavy Goods Vehicles will be diverted along the A33 to M3 junction 7, then south along the M3 to access junction 9.

We encourage drivers to stick to speed limits and follow appropriate signage to ensure the safety of those working on site and fellow road users.

Concrete repairs are taking place to the bridge which carries the A272 over the A34 at Three Maids Hill, north of Winchester (Hampshire).

These repairs will improve the longevity of the bridge and ensure safety for our customers.

Specialist scaffolding will be in place below the bridge, and our teams will be elevated platforms to reach the areas to be repaired.

Narrow lanes and a 50mph speed limit will be in place on the A34 northbound and southbound carriageways for the duration of the repairs. There will also be a lane closure and a 30mph speed limit on the A272 in both directions across the bridge.

The A34 north and southbound carriageways between the A303 Bullington Cross and the A33 Kings Worthy link will be closed overnight on Tuesday 4 May 2021. Diversions will be in place via the A303 and M3 for motorway permitted vehicles, and via the A303 and A33 for non-motorway vehicles.

The A34 southbound carriageway will then be closed from the A303 to the A33 Kings Worthy at night from Wednesday 5 May until Friday 13 August. Clearly signed diversions will be in place using the A303 and M3 for motorway permitted vehicles, and via the A303 and A33 for non-motorway vehicles.

This will be followed by overnight closures of the A34 northbound carriageway beneath the bridge only from Monday 16 August through to Friday 15 October. Traffic will be diverted off the A34 via the exit slip road at the junction, around the Three Maids Hill roundabout, then re-join the A34 via the northbound entry slip road.

All closures will be between 9pm and 6am, Monday to Friday nights only.

Located off the A34 near Drayton, is an area which was previously constructed as part of an old Drayton slip road, but is now used as an unofficial layby. We are converting this area into an official standard layby by carrying out major reconstruction to the embankment. Work will also involve:

  • realigning the verges;
  • updating the safety barrier;
  • installing new timber fencing;
  • resurfacing and laying of new road markings;
  • improve drainage; and
  • installing new layby signs.

As part of this project, additional work will take place to the old Drayton Road/Steventon Road slip road embankment area, to prevent anyone from parking illegally. The works will include:

  • replacing the existing gates to heavy duty gates;
  • installing a small section of interlocking concrete blocks;
  • installing new timber fencing;
  • planting new vegetation; and
  • removing the old concrete blocks.

The existing unofficial lay-by will be closed from 9 June 2021 until the completion of the work.

Narrow lanes and a 50mph speed limit will be in place on the A34 northbound carriageway (next to the work area) from Monday 21 June until mid-September 2021.

In addition, the A34 northbound carriageway between the Milton Interchange and Marcham Interchange, will be closed overnight (9pm to 6am) on the following dates to allow the traffic management to be installed and then removed:

  • Monday 21 and Tuesday 22 June
  • Saturday 11, Sunday 12 and Monday 13 September

A signed diversion will be in place via the A4130 from Didcot to Wallingford, then north on the A4074 towards Oxford. From here road users can re-join the A34 north or southbound carriageways depending on their destination.

We’re resurfacing the A34 southbound carriageway, starting north of the A420 Botley Interchange down to South Hinksey. This work will improve the condition of the road and journeys for our customers.

For the safety of our workforce and customers, the A34 southbound carriageway will be closed at night from the A44 Peartree Interchange to the A423 Hinksey Hill junction. The closures will be in place from 9pm to 6am (Monday to Friday nights only), when there are fewer vehicles on the road.

A signed diversion route will be in place via the Oxford ring-road (A44, A40, A4142 and A423).

We're resurfacing the A404 southbound carriageway, from the M40 junction 4 Handy Cross roundabout to the Westhorpe roundabout at Marlow. Work will also include renewing the road markings, road studs and laying an anti-skid surfacing as required.

Between 17 May and 18 June, we will be closing the A404 southbound carriageway between the M40 and the Marlow Westhorpe Interchange overnight, between 9pm and 6am (Monday to Friday nights only). A signed diversion in place via Wycombe Road.

Over three nights from Monday 28 June, we will be closing the A404 southbound carriageway from the Marlow Westhorpe Interchange to the Bisham roundabout. A signed diversion will be in place via Henley-on-Thames for vehicles under 7.5 tonnes; vehicles over this weight will be diverted via the M40, M25 and M4.

We’d advise all motorists to stick to the signed diversion route as this has been chosen with both suitability and safety in mind. We’d also encourage drivers to stick to speed limits and follow appropriate signage to ensure the safety of those working on site and fellow road users.

We’re resurfacing a section of the M3 northbound carriageway near Hatch (junctions 6 to 5), to ensure the network remains in a safe condition for road users.

As part of the project, we will be trialling the use of recycled materials in the new carriageway surface. We will be using the highest percentage of recycled materials that has been used on any part of our network. A previous project on the M25 used 50% recycled materials. The M3 Hatch project will be using 70% recycled materials in the binder and base course and 50% in the surface course.

The recycled materials are taken from previous resurfacing projects, and have stored and treated at our contractor’s plant near Heathrow. The M3 site will be monitored annually, to see how the recycled materials preform in relations to non-recycled materials. The carbon saving from using recycled materials will provide a foundation piece for Highways England achieving the carbon saving goal.

The M3 northbound carriageway between junctions 6 and 5 will be closed overnight, 9pm to 6am (Monday to Friday nights only), when there are fewer vehicles on the road.

During the closure, a signed diversion will be in place via the A30 and A287.

We’d advise all motorists to stick to the signed diversion routes as they have been chosen with both suitability and safety in mind. Please adhere to all speed limits and follow appropriate signage to ensure the safety of those working on site and fellow road users.

We will do our very best to complete the work as quickly as possible, keeping disturbances and noise to a minimum.

 

We’re upgrading the traffic signals around junction 12 of the M4 at Theale (Berkshire). Work will involve replacing the traffic signals around junction 12 with new LED signals and controllers. The refurbishments will include upgrading to extra low voltage cabling and equipment to reduce our carbon footprint and energy costs.

Throughout the work, different sections of the roundabout will be closed overnight (between 9pm and 6am). These sections are currently scheduled as follows, but are subject to change:

  • Monday 28 June to Friday 2 July – Closure of the west side of the junction
  • Monday 5 July to Friday 9 July – Closure of the east side of the junction
  • Monday 12 July to Friday 10 September – Lane closures on the roundabout
  • Monday 13 September to Friday 24 September – Closure of the west side of the junction
  • Monday 27 September to Friday 8 October – Closure of the east side of the junction

Signed diversions will be in place via adjacent junctions for closures of the M4 slip road.

In addition, the following diversions will be in place for closures of the A4 exits from the roundabouts:

  • Closure of the access from roundabout to A4 Bath Road (Theale side) – traffic will be diverted towards Reading centre, then the A329 to Pangbourne, then A340 to Theale
  • Closure of the access from roundabout to A4 Bath Road (Calcot side) – traffic will be diverted along Bath Road, then north on the A340 to Pangbourne, along the A329 towards Reading centre, then along the A4 to Calcot

We are repairing the bridge which carries the M4 over Welford Road (near Wickham, West Berkshire), which is damaged due to water leaking through the joints. To ensure the bridge remains in a safe condition, work will include:

  • Reconstructing the central reservation
  • Replacing the joints across the M4 motorway
  • Replacing the waterproofing material below the carriageway surface
  • Resurfacing the M4 across the bridge
  • Upgrading the safety barrier along the M4 verges

For the safety of our workforce and customers, the following traffic management restrictions will be in place on both the M4 eastbound and westbound, and on Welford Road beneath the bridge:

M4 motorway

From Monday 10 May until Friday 2 July 2021, there will be a 24/7 closure of the hard shoulder on both carriageways and overnight lane closures.

Then from Monday 5 July 2021 for up-to 12 weeks, 24/7 narrow lanes and an enforceable 50mph speed limit will be in place on both the westbound and eastbound carriageways. Free vehicle recovery will be available for anyone who breaks down in the narrow lanes.

Once the central reservation has been replaced, the narrow lanes will be removed, and the remaining activities will be done using full weekend closures of the M4 eastbound and westbound carriageways.

M4 junctions 13 to 14 weekend closures

To replace the central reservation, a large crane will be required, and we will need to close the entire motorway for the full weekend. A further weekend closure of the M4 will be required to replace the waterproofing material and surfacing. This is to allow enough time for the material to cure.

These weekend closures will be between junctions 13 and 14. The dates of the weekend closures are currently planned as follows:

  • 9pm on Friday 30 July through to 6am on Monday 2 August
  • 9pm on Friday 20 August through to 6am on Monday 23 August
  • 9pm on Friday 10 September through to 6am on Monday 13 September (contingency)
  • 9pm on Friday 24 September through to 6am on Monday 27 September
  • 9pm on Friday 8 October through to 6am on Monday 11 October (contingency)

During these closures, signed diversions will be in place via the A338, A4 and A34.

We're resurfacing a section of the M4 eastbound carriageway near Liddington (junctions 15 to 14), to address surface defects and ensure the network remains in a safe condition for our customers.

The M4 eastbound carriageway, between junctions 15 and 14, will be closed overnight between Monday 7 and Friday 18 June (9pm to 6am, Monday to Friday nights only).

During the closure, light vehicles will be diverted via the A419, then the B4192 through Liddington, Aldbourne and Chilton Foliat, then north at Hungerford to re-join the M4 at junction 14.

Heavy Goods Vehicles will be diverted via the A346 to Marlborough, then the A4 to Hungerford, then north on the A338. As the light vehicle route is unsuitable for this type of vehicle.

We’re resurfacing the M23 in both directions, between junctions 8 and 10, to ensure the network remains in a safe condition for our customers. Work will also include renewal of road markings and road studs, and applying anti-skid material where necessary.

For everyone's safety, the M23 will be closed overnight from 8pm to 5am (Monday to Friday nights only), as follows:

  • Monday 7 June to Wednesday 30 June – closure of the southbound carriageway between junction 8 (M25) and junction 10 (Crawley Interchange)
  • Monday 5 July to Tuesday 27 July – closure of the northbound carriageway between junction 10 (Crawley Interchange) and junction 8 (M25)

Diversions

Traffic wishing to travel south down the M23 towards Gatwick, will be diverted along to junction 6 of the M25 (Godstone), south down the A22 to Felbridge, then west along the A264 Copthorne Road to join the M23 at junction 10.

Traffic for Gatwick Airport will use the same diversion route as above, then from junction 10 of the M23, travel west along the A2011, then north on A23 London Road towards the airport.

Traffic wishing to travel north on the M23 towards the M25 and London will be diverted from junction 10, east along the A264 Copthorne Road to Felbridge, then north on the A22 to access the M25 at junction 6. 

Traffic from the south travelling north for Gatwick Airport, will need to head towards M23 junction 10 then travel west along the A2011, and north on A23 London Road towards the airport.

We’d advise all motorists to stick to the signed diversion routes as they have been chosen with both suitability and safety in mind. Please adhere to all speed limits and follow appropriate signage to ensure the safety of those working on site and fellow road users.

We will do our very best to complete the work as quickly as possible, keeping disturbances and noise to a minimum.

We’re carrying out work to replace the parapets on the bridges which carry the M27 over the Portsbridge roundabout. We will also be replacing the joints in the bridges which carry the A27 Havant Bypass over the A2030 Eastern Road roundabout.

Due to the worsening condition of the parapets, these works have been brought forward to ensure the safety of our road users.

To allow us to carry out these works safely, we will need to close the M27/A27 in both directions overnight (9.00pm to 6.00am, Monday to Friday) between junction 12 of the M27 and the A27/A2030 Eastern Road Interchange.

The road will remain open during daytime hours and an enforceable 40mph speed limit with temporary safety barrier will be in place, to protect the parapets for the work duration.

We will do our very best to complete the work as quickly as possible, keeping disturbances and noise to a minimum.
