The Mountain Road will close for up to three evenings later this month as last-minute work takes place to make sure everything's ready for TT.
The Department of Infrastructure says it needs to trim hedges and verges ready for this year's festival.
As a result, it'll do the work on closed roads from Monday, May 18 until Thursday, May 21.
The route will close from 6.30pm until 10.30pm each evening.
