The main A970 at Levenwick will be closed today for some time to allow the recovery of a lorry which came off the road yesterday.
The incident happened around tea time on Monday, when a Garriock Bros low-loader carrying a digger tumbled over the embankment on the lower side of the road. The driver luckily escaped uninjured.
According to the SIC roads service the work to recover the lorry is expected to take several hours today. Workmen were on site today trying to recover the vehicles.
Communications spokesman Bob Kerr said: “Alternative routes exist through the Levenwick loop road; and through Bigton and Scousburgh.
“Both of these roads are single track roads with passing places and drivers may expect some congestion and delays.
“Anyone travelling to Sumburgh Airport to connect with a flight should allow extra time for their journey.”
