The A30 is closed in both directions at Zelah this evening after a motorised crane caught fire.
Emergency services were called to the scene on the Eastbound carriageway at Marazanvose just after 3.30pm. Traffic has also been stopped on the Westbound carriageway.
One crew from Truro Fire Station attended and extinguished the fire. Police have confirmed the driver is safe out of the vehicle.
The road will remain closed from Short Lanes to Zelah Hill to assist operations until the crane has been recovered.
