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:

  • 9pm on Friday 11 June through to 6am on Monday 14 June 2021
  • 9pm on Friday 18 June through to 6am on Monday 21 June 2021

Coast-bound (eastbound) carriageway:

  • 6am on Saturday 26 June through to 6am on Monday 28 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 replacing the joints in the bridge which carries Bell Hill road over the A3 near Petersfield. This work will ensure the integrity of the bridge and maintain safety for our customers.

To undertake these works safely, we’ll be closing the A3 Bell Hill bridge on the following dates:

Weekend One Closure - 8am Saturday 5 June to 6am Sunday 6 June 2021

Weekend Two Closure - 8am Saturday 12 June to 6am Sunday 13 June 2021

Bell Hill road either side of the bridge will remain open to allow access for residents and businesses.

Access be maintained across the bridge for pedestrians, cyclists and other non-motorised users.

Diversion Route for both directions:

Bell Hill, Winchester Road, A272, A32, onto Bell Hill signed ‘Steep and Froxfield'.

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.

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, Monday to Friday nights only. At present, the following closures have been scheduled:

Tuesday 4 May for approximately two weeks

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

Diversion via the A349 and A350.

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.

Wednesday 9 June for two nights

Closure of the A31 eastbound and westbound between the Canford Bottom junction and the A347 Palmersford roundabout (Ferndown).

Diversion via Wimborne Road East/West.

Friday 11 June for one night

Closure of the A31 eastbound and westbound between the Merley roundabout and Canford Bottom junction (Wimborne)

Diversion via the B3073, B348, A341 and A349

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 Monday 21 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 to set up, amend and remove the traffic management. The provisional dates for these closures are:

  • Saturday 15 and Sunday 16 May 2021
  • Saturday 12 and Sunday 13 June 2021
  • Saturday 26 and Sunday 27 June 2021
  • Saturday 31 July and Sunday 1 August 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.

The images below show the concrete damage beneath the bridge:

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.

Overnight on Monday 28 and Tuesday 29 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 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.

Welford Road

Whilst we are replacing the central reservation of the M4 above, we will close Welford Road from Monday 12 July through to Saturday 18 September 2021. Access will be maintained for pedestrians and cyclists, and for emergency services.

A diversion will be in place via Welford Road, Rood Hill, High Street and the B4000.

Welford Road diversion route map

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, a signed diversion will be in place via the A346, A4 and A338.

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.

Diversions

Eastbound traffic will be diverted from M27 junction 12 via the A3 Southampton Road, Havant Road and A2030 Eastern Road.

Westbound traffic will be diverted from the Eastern Road roundabout, north on the A2030, west along the Havant Road, A3 Southampton then down to M27 junction 12.

We’d advise all motorists to follow the signed diversion routes as they have been chosen with both suitability and safety in mind.
