Kier Highways, on behalf of Highways England, will be undertaking essential maintenance work to replace a section of severely corroded vehicle safety barrier located alongside the A303 eastbound carriageway at Forton.  Works will also include diverting electricity cables under the A303 and removal of an existing electricity pole.

Work is currently scheduled to start on Monday 4 March 2019 and is expected to take up-to five weeks to complete.

For the safety of our workforce and customers, the A303 eastbound carriageway will be closed overnight (between 9pm and 6am, Monday to Friday only) from the A3093 Picket Twenty junction to the Barton Stacey junction.

In addition, whilst diversion of the electricity cables is taking place we will also be closing the A303 westbound carriageway from the A34 Bullington Cross junction to the Longparish junction. This is currently scheduled to take place overnight on Wednesday 20 March 2019, but is subject to change.

During the closures the following clearly signed diversions will be in place:

  • A303 Eastbound – traffic will be diverted off the A303 at Picket Twenty, continue north on the A3093 until the roundabout with the A343. Continue north on the A343 until the Wash Common junction on the A34, then travel south on the A34 to the Bullington Cross junction and then re-join the A303 eastbound
  • A303 Westbound – traffic will be diverted off the A303 at Bullington Cross and continue south on Bullington Lane to join the A30 at Sutton Scotney. Turn right at the roundabout to go northbound on the A3057 Leckford Lane.  Re-join the A303 westbound at the A3057  Winchester Road junction to the south of Andover

Access will be maintained for emergency service vehicles on blue light calls.

Please be aware that these works have been carefully programmed but are subject to change due to weather conditions or unforeseen circumstances – please check the yellow signs placed in advance at the junction for confirmation of the closures dates/timings.
