A bulldozer was needed to shift an industrial cement mixer which had become detached from its truck and was blocking the road near Sumburgh Airport.
The incident occurred at about 12.20pm and the police were called to the scene. Initially, one lane of the A970 was blocked and the road was only passable for cars and small vehicles.
But the bulldozer shifted the unit to the side of the road. No-one was injured.
• The road between the Sumburgh Hotel and the airport will be closed for between three and four hours from 8.30pm to allow the removal of the cement trailer.
