Part of the TT course will close for a week during daytime next month.
The Department of Infrastructure says surveying work means it'll need to close the road between Ballig Bridge and Cronk-Y-Voddy crossroads.
The route will be shut from 9.00am until 3.30pm each day between Monday, January 13 and Friday, January 17.
The DOI says if all goes according to plan, it should only need two days to complete the work.
