The hill which runs alongside Kewaigue School is being closed to traffic about now (4pm) so a potentially dangerous tree can be taken down.
A team is in position, ready to remove the offending item, which is immediately across the road from the school.
Manx Radio has been told the job is expected to take about two hours, which means motorists making their way home will have to find alternative routes, up to about 6pm.
