Traffic lights will be in operation 24 hours a day
Works to reduce the risk of trees falling on the Laxey to Ramsey coast road will continue until next month.
A large tree fell and blocked the road earlier this week, but an assessment by the Department of Infrastructure found more trees at risk of doing the same.
Temporary traffic lights will be in operation between Greens Garage and Ard Reayrt 24 hours a day until 6 December.
