NATIONAL Highways is advising motorists to plan their journeys along the A303 ahead of this weekend’s Summer Solstice event at Stonehenge.

The event will take place on Friday, June 20 and the morning of Saturday, June 21, and with limited parking on site.

Car parking will be available from 7pm on June 20 until 6am on June 21, and will shut once full. The car park will be vacated by noon on the Saturday.

Buses will run from Salisbury and pedestrians are advised to use the designated, temporary pedestrian crossing on the A303 at Stonehenge Cottages

During the Solstice event, National Highways will assist the flow of traffic before, during and after the event.

A 40mph speed limit will be in place on the A303 between the Countess roundabout and Longbarrow roundabout, with the lay-bys closed in between, and the dual carriageway will be reduced to a single lane between Countess Roundabout and Stonehenge Cottages.

Traffic is diverted via the A345 and sections of the A303 and A36, and a comprehensive signage system will be in place to inform road users around Salisbury and as far away as Devizes and Shaftesbury to point traffic to alternate routes.

Drivers are advised to follow the solstice specific signs rather than their sat navs, and can obtain up-to-the-minute travel information online or by phoning the National Highways customer contact centre on 0300 123 5000.
