The Mountain Road will be closed this weekend for essential work ahead of the Festival of Motorcycling.
The route will be closed from Barrule Park to the Creg-ny-Baa from 6pm on Saturday until 6am on Monday morning.
According to the Department of Infrastructure the work is in response to feedback provided by TT riders and improvements they want for areas like the Black Hut.
Operations manager Kerrin Wells says despite a number of crashes on open roads the changes are predominantly being made due to racing issues:
