The Mountain Road will close for two evenings early next month - as preparations for racing get underway.
The Department of Infrastructure says it'll close the route between Barrule Park and the Creg ny Baa on Tuesday, August 8 and Wednesday, August 9.
Patching, hedge trimming and sweeping means the road will be closed from 6.30pm to 10.30pm on both days.
Motorists are being advised to use alternative routes.
