Essential surfacing works need to be carried out on the A36 between the Southampton Road junction and the exit slip road to Alderbury village  To minimise disruption, we’ll work overnight when there are fewer vehicles on the road. During the day we will keep the carriageway open as usual.

Work will start on the evening of Monday 26 July and finish October 2021. Work will take place overnight Sunday to Thursday only between 8pm and 6am, in 4 phases:

  • Phase 1 – 26 July to 5 August: full north and southbound closure
  • Phase 2 – 8 to 23 August: northbound closure only
  • Phase 3 – 24 August to 25 September: 2-way lights
  • Phase 4 - 26 September to October: lane closures will be in place

During the closures, fully signed diversion routes will be in place. Please allow extra time for your journey.

Highways England is funding this project to widen Mowhay Footbridge which crosses the A38 in Plymouth. Our Cycling, Safety and Innovation fund focuses on providing a more accessible, inclusive and integrated network. This includes improving cycling facilities, enhancing safety measures, expanding travel choices for a variety of users and creating improved connectivity for users and communities. 

Since 2015 Highways England has invested more than £85 million towards the creation of 160 new and upgraded cycleways across England, providing safe, attractive and accessible facilities for people to cycle for work, shopping and leisure.

By improving the connection between Honicknowle, Weston Mill and St Budeaux further recreational opportunities will be unlocked in Plymouth and  commuters will be provided with a new facility enabling them to actively choose an alternative sustainable method of transport.

We will be widening the existing bridge deck to provide a shared facility for cyclists and installing a new ramp and steps at the south end of the bridge.  We will also install lighting to make the bridge safer at night. 

To carry out the work safely we'll need to close Mowhay footbridge for approximately 7 months and some overnight closures of the A38 below will be needed to install scaffolding and safety barriers and elements of the new bridge deck. Where possible our operational team will make use of these closures to carry out repairs and maintenance on the A38 carriageway.

The bridge will be closed to the public from 12 July 2021 with a target to reopen in February 2022. Suggested alternative routes can be found below and further information can be found at www.plymouth.gov.uk/walkcyclemap 

August 2021 update

  • The site access road has now been constructed, which has allowed the setting up of the site compound including the contractors’ welfare facilities.
  • Demolition works have started for the elements of the bridge that are being replaced and the removal of the original steps and ramp is now complete. The concrete pours for the foundations of the new ramp and steps are progressing well.
  • We have removed the existing surfacing on the bridge deck, allowing us to undertake a detailed condition survey before re-waterproofing works commence.
  • At the end of August, we will start our night works which will include further demolition of the bridge parapets.  This will be start of our programme of night-time closures of the A38 (see advance warning section below). We'll make use of these overnight closures to undertake additional work such as resurfacing and general maintenance.

 

 

 

We’re undertaking works to improve the circulation of traffic to tackle congestion at the M4 junction 15 at Swindon.

Works will include:

  • widening of the A419 southbound approach to M4 junction 15 Commonhead roundabout from 2 to 3 lanes, with a dedicated left lane for London-bound traffic
  • widening of the M4 junction 15 northbound exit to the A419
  • widening of the A346 to the south of M4 junction 15
  • widening of the M4 J15 eastbound exit-slip
  • M4 junction 15 westbound exit-slip road, lengthening of the 3-lane section
  • widening the M4 junction 15 southern circulatory carriageway from 2 to 4 lanes
  • upgrade of existing footpaths and installation of a new signalised pedestrian crossing over the M4 junction 15 westbound entry-slip road

Update - November 2020

We’re continuing to make good progress despite restrictions during the pandemic and changes in the way we work to ensure the safety of our workforce.

Drainage and embankment works are progressing well in the north east corner of the site on the A419.

We’ve started widening both the circulatory and the westbound off-slip and we’ve also cleared vegetation on the southwest corner in readiness for drainage works.

The next phase will see vegetation clearance being carried out on the southeast corner of the A419.  Then we’ll begin reconstruction of the westbound off-slip carriageway, followed by drainage and widening works on both the southeast and southwest quadrants of the circulatory.

Thank you for your patience while these works are carried out. We always aim to work to programme, however adverse weather or unforeseen circumstances may mean changes to our plans. If you have any questions or comments about the work, or would like further information, please contact Highways England Customer Contact Centre on 0300 123 5000 (open 24/7) or email us at: info@highwaysengland.co.uk

Update March 2021

Progress on the junction has been good and the new layout is starting to take shape.

The landscape within the roundabout itself looks significantly different with trees and shrubs having been cleared to allow widening of the inner roundabout later in the spring.

At the A419 southbound, the earthworks and new embankment to support the new dedicated lane to the M4 eastbound are almost complete.

The A419 northbound diversion of services by Open Reach and Thames Water will also be finished soon.

We'll begin installing underground ducting for traffic signals and street lighting on the junction.

The A419 southbound embankment is 90% complete. Over the next couple of months we'll start working on the drainage, road construction, noise and safety fencing.

On 6 April works will begin under Day House Lane bridge to install a new access for pedestrians, cyclists and horse riders. There will be no access under the bridge until works complete at the end of October.

 

Update June 2021

Roundabout works - works on the inner northeast section of the roundabout are nearly complete, the kerbing, noise barrier, safety barrier and surfacing have been completed allowing the traffic to be moved to the outside of the roundabout. 

Kerbing, ducting and drainage works on the northwest section of roundabout are almost complete and work has begun on safety barriers. Footpath works have also started.

Embankment construction, drainage, ducting and road construction to the south of the roundabout have progressed well, installation of kerbing to follow.

Work will begin on the northeast outer section of the roundabout next month. We also plan to resurface the southern section of the roundabout and the footpath.

Day House Lane works - preparation for the installation of the pre-cast units has been completed.  The first delivery of pre-cast culverts and wingwalls have arrived on site and are now in place.

 

Update September 2021

We are currently on track to complete major works to this junction by Friday 15 October.

 

Update October 2021

At National Highways our mission is to keep the South West connected to the rest of the world. By maintaining and developing our roads, we connect people and communities and we support industry, helping businesses, large and small, reach key markets. Our Designated Growth and Housing Fund has helped to unlock growth for Swindon on the M4 at J15.

The multi-million pound scheme, which will tackle congestion and help unlock thousands of new homes in Swindon, has opened to traffic following 17 months of work. 

National Highways teamed up with Swindon Borough Council, Swindon and Wiltshire Local Enterprise Partnership and developers Persimmon and Redrow to deliver extra lanes at M4 Junction 15 and improve local road access from the motorway. 

The £17 million project started last June and will improve journey times and reliability for motorists by tackling congestion at both the busy M4 junction and on the A419, particularly at peak times in the area.

Bridge deck refurbishment to include:

  • Removal and reconstruction of parapet edge beams
  • Full parapet and adjacent safety fencing replacement
  • Replacement of expansion joints
  • Localised concrete repairs
  • Remove existing run-on slabs
  • Re-waterproof and re-surface carriageway and footway decks
Update November 2020

Staverton bridge has been carrying B4634 traffic over the M5 since the 1970s and is now in need of refurbishment. We’re continuing to make good progress despite changes in the way we work to ensure our workforce remain safe during the Covid pandemic. 

 We’ve almost completed phase 1 which was the most complex and time consuming. This involved stripping back part of the top layer of concrete on the bridge deck, carried out full inspections of steel work, replaced damaged steel and added anodes to reduce further concrete and steel deterioration.

Further concrete removal is needed, and this will take place in a series of 13 sections spread across the bridge, to ensure the deck remains stable.

 

Steel inspection works

 

Update April 2021

Most of the top deck hydro demolition and concrete repairs are now complete with two of the major and 4 of the minor phases complete.

We're also working on the west end of the bridge, works will involve rectifying the defects on the ballast wall, outer face and underside of the bridge.

 

Update July 2021

We have completed all concrete works on top of the deck and we're now working on the underside edgebeams.

The western abutment is almost complete and we'll be moving to the eastern side shortly.

Work on the Public Right of Way is progressing well and we'll open it for public use as soon as possible. 

We are carrying out full refurbishment of the two main bridges that support the M5 J11 Golden Valley gyratory linking the M5 and the A40.  The majority of work will be carried out on the north to south bridges. This 18-month scheme will see removal and reconstruction of ballast walls, concrete repairs to the bridge deck, replacement of bridge bearings, removal and reconstruction of parapet edge beams and safety fencing, and finally waterproofing and resurfacing of the carriageway and footpath. Motorists travelling to Cheltenham or Gloucester may wish to consider using alternative junctions to avoid potential delays. 

The works will be carried out under a full closure of the gyratory. Motorists will be able to join and leave the M5 via the slip roads but will be unable to circle round the gyratory.

Update November 2020

We’re continuing to make good progress despite restrictions during the pandemic and changes in the way we work to ensure the safety of our workforce.

We’ve cleared the area of vegetation, set up welfare facilities, dug site trial holes to check for existing services, prepared access for abutment scaffolding,

Removed bridge deck surfacing and removed deck run on/off slabs.

Deck run on/off slabs removed

Deck run on/off slabs removed

 

Update February 2021

We've made good progress throughout January and works are currently on schedule:

  • Hydrodemolition  to access the post tensioned anchorages, has been completed
  • Post tensioned anchorages at all four deck ends have been exposed and inspected
  • Concrete repairs to deck ends have started following removal of defective concrete. These repairs are done in a set sequence, one small area at a time
  • Post tensioning duct investigations on the top deck are almost complete
  • We've started to install foundations for temporary access bridges to allow our workforce and machinery  to work on decks more easily

Work will continue over the next few months to remove and repair defective concrete to all four deck ends of the Golden Valley bridges.

At the same time we'll also be taking the opportunity to  repair the  concrete A frames on the Golden Valley east and west bridges. These structures support the A40 dual carriageway over the top of  the J11 gyratory,  the works are all below the bridge decks and will not impact the A40.  Preparations are ongoing for this work to begin late March 2021. Works will take place within the existing traffic management.

 

Update June 2021

Good progress is being made with site works and the scheme remains on target to complete in March 2022. Here's a quick overview on what we're currently working on:

  • All four deck ends and post tensioned anchorages have been exposed and inspected.
  • Hydrodemolition and concrete repairs to existing deck end and soffit concrete are approximately 50% complete.
  • Top deck post tensioning investigations are continuing.
  • Concrete testing of upper deck completed on both bridges.
  • Temporary site access bridges on to both bridge decks have been installed.
  • Scaffold temporary works platforms for parapet replacement works have been erected on both bridges.
  • Hydrodemolition of north bridge parapet edge beam is ongoing.
  • Bridge deck jacking and bearing replacement works have begun.
  • Golden Valley east and west supporting A frame repairs are continuing in line with expectation.

Work will continue to remove and repair defective concrete to all four deck ends of the Golden Valley bridges.

At the same time we'll also be working on the  concrete A frames on the Golden Valley east and west bridges.

 

Update October 2021

We've taken the scaffolding down and we're still on target to complete March 2022

M5 north and south bridge decks

  • Scaffold platforms for parapet replacement works have been removed from both bridge decks
  • The temporary bridges used to access the decks are now being removed
  • Bridge deck jacking and bearing replacement works are now complete
  • Bridge deck end rear and wing walls are being reconstructed
  • Hydrodemolition and concrete repairs to existing deck end and soffit concrete are almost complete
  • Top deck post tensioning investigations are complete on north deck and ongoing on the south deck
  • Parapet works are substantially complete

A40 east and west bridge decks

  • Repairs to the east bridge decks have been successfully completed
  • Repairs to the west bridge decks are almost complete

Over the next few months we'll continue to work on the bridge deck repairs, in tandem with reconstruction of walls and backfilling at either end of the deck.

Once complete, we'll move on to waterproofing and surfacing works.

This section of carriageway is often congested and we're installing equipment to improve the situation for motorists.

At the moment there is limited technology to help network management and provide information to motorists. This scheme will see the installation of  Motorway Incident Detection and Signaling (MIDAS) technology. The enhanced CCTV coverage and message boards will allow us to monitor the network more effectively, warn drivers of road conditions, manage traffic speeds during times of congestion, provide improved network information and enable better management of incidents.

To minimise inconvenience, we've maintained capacity by installing 3 narrow lanes and where possible, we've kept the M5 open while works are carried out. We've been able to complete some of the work during the day, but the more complex operations have been carried out at night when traffic flows are lowest, to help protect our workforce.  We've kept overnight closures to a minimum and re-opened the carriageway early when possible.

 

Progress update

We have completed the installation of eleven new gantries and the associated infrastructure works at J23 and J25. The electronic message boards will be fixed to the gantries during July. 

 

Next steps

The next phase of our work will be to install a total of six new message signs on the north and south approaches to J24. 

This is currently due to begin in October 2021 and complete in March 2022.  As before, we'll maintain capacity by installing 3 narrow lanes with a 50 mph speed limit on both the southbound and northbound carriageways and we'll follow a similar work pattern, only closing the M5 overnight when absolutely necessary.

We’ll be installing additional safety barriers, where there are gaps, along this stretch of the M5 from October to March 2022. The work will be carried out in phases, we'll work overnight Sunday to Thursday 8pm in the evening to 6am the following morning. Hard shoulder and lane 1 closures (with some slip road closures) will be in place while we're working. The road will be open as usual during the day.

We’ll make every effort to ensure the impact on the local community and traveling public is kept to a minimum.

Our planned works are listed below.  We always aim to work to the programme, however unforeseen circumstances or adverse weather conditions may mean changes. 

Safety barrier replacement works are planned for:
10/10/21 – 25/10/21 - J11-J10 northbound
25/10/21 - 05/12/22 - J10-J9 northbound
06/12/21 – 16/02/22 - J12-J11 northbound
20/02/22 – 27/3/22 - J11-J12 southbound

Slip road closures are planned for:
24/02/22 – 27/02/22 - J11a northbound
28/02/22 – 06/03/22 - J11 northbound
07/03/22 – 10/03/22 - J10 northbound
13/03/22 – 17/03/22 - J9 northbound

We have now completed vegetation clearance and survey works on the site and are ready to move to the next stage of works.

The reconstruction of the embankment is complex and will need to be carried out in 2 phases. Phase 1 will see the installation of drains to lower the water level and phase 2 will see reconstruction of the embankment and reinstatement of the eastbound carriageway.

Phase 1 will begin at the end of October and we estimate it will take approximately 5 months to lower the water level sufficiently. Works will take place during daytime hours and the current eastbound traffic light system will remain in place 24/7.

Phase 2 will begin in April 2022.
