Motorists are being reminded the Beinn-y-Phott Road will be subject to closures during the day this week.
The Department of Infrastructure says the route will close between the A3 Castletown to Ramsey Road and the Mountain Road between 9am and 4pm from Monday to Friday (August 24-28).
It comes after work on the stretch was postponed from last week due to poor weather conditions.
Contractors will be carrying out lining work, hedge cutting and ditch clearing.
