The Department of Infrastructure says it won't close two parts of the TT course outside Ramsey at the same time.
Repairs and TT preparations means it'll shut Lezayre Road between Sulby and Glen Auldyn from 9.30am on Monday, April 20 until 3.30pm on Friday, April 25.
On Facebook, it's posted more details about diversions, bus services and access to properties.
But it also says if the Mountain Road is still closed because work has been delayed, it'll put back working on Lezayre Road - saying both will not be closed at the same time.
