Replacement of street lighting along A36 between St Paul's roundabout and Bourne roundabout.

We will be reducing:

  • lighting columns by 22% from 180 to 140
  • street light bulbs by 41% from 242 to 144
  • illuminated signs by 18% from 106 to 87
  • non-illuminated signs by 50% from 64 to 32

We will also be replacing illuminated bollards with reflective versions.

We predict that the switch from current high pressure sodium lightbulbs to an energy efficient LED system will bring a carbon and energy cost saving of 66%. This will reduce our current predicted running costs from £28,00 to £9.700

The underpass which carries the A303 over the B3095, near Mere is in need of repair. We’ll carry out concrete repairs, re-waterproof, replace bridge joints, and finally replace surfacing and lining.

The bridge which carries the A303 over the River Avon (to the east of Countess roundabout) is in need of repair ahead of our Amesbury to Berwick Down improvement scheme. We’ll carry out concrete repairs, replace the bridge bearings and joints and finally replace surfacing and lining.

The majority of work will be carried out under lane closures. However full overnight closures will be in place for bearing and joint replacement. We’ll work overnight when traffic flows are at their lowest, both directions of travel will be affected.

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

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

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.

This junction often becomes gridlocked during peak traffic flow.  In order to alleviate congestion we’re reconfiguring the lanes within the exit-slip and roundabout to allow traffic to flow more freely. To minimise disruption to motorists we’re co-ordinating our works with Wales and West Utility Company. 

The work will take place in three phases.  Our preparatory work will begin at the end of June, Wales and West will then carry out their works and finally we’ll return to site to complete our traffic flow improvement works.

We are carrying out full refurbishment of the north and south bridge decks which support the M5 J27 Sampford Peverell gyratory linking the M5, A361 and A38. 

The majority of work will be carried out on the north to south bridges. This 3-month scheme will see concrete repairs to the bridge deck, waterproofing, resurfacing and lining and replacement of bridge joints.
