The TT access road will be closed for drainage works this summer.
The route which runs alongside Peel Road in Douglas will shut to pedestrians from Monday, June 16 until the end of July.
It's to allow for work to be completed along the route at Quarterbridge.
Access to the old Douglas to Peel railway line will remain via the Joey Dunlop Foundation.
