WILTSHIRE'S busiest road has been closed in both directions after a serious crash.

A pedestrian and a HGV were involved in the incident on the A303 near Stonehenge at the Amesbury bypass. This has shut the road between the Countess and Longbarrow roundabouts (the A345 and the A360).

Traffic is coping well and using the diversion routes which head around Lark Hill. Delays of less than 10 minutes.

It is not known when the road will reopen.

UPDATE: A man involved in the collision has died
