Drivers have been warned of delays on one of Wiltshire’s busiest A-roads during a popular event.

National Highways has advised motorists using the A303 to leave extra time for their journeys and plan ahead during the week of the Summer Solstice on Thursday, June 20.

Large crowds flock to Stonehenge for the event each year, which will start at 7pm and continue until 8am on Friday, June 21.

National Highways will be assisting with the flow of traffic before, during, and after the event.

A 40mph speed limit will be implemented on the A303 between the Countess roundabout and Longbarrow roundabout, with the lay-bys closed in between.

The dual carriageway will also be reduced to a single lane between Countess Roundabout and Stonehenge Cottages. 

Car parking will be available from 7pm on Thursday until 6am on Friday, but will shut once full.

The car park will be vacated by noon on the Friday.

English Heritage has urged visitors to use buses, which will run from Salisbury, or car share.

Pedestrians should use the designated, temporary pedestrian crossing on the A303 at Stonehenge Cottages.

Meanwhile a section of the A360, between The Avenue and Longbarrow, remains closed for Scottish and Southern Electricity Networks work.

Traffic will be diverted, via the A345 and sections of the A303 and A36, by signage.
