The Department of Infrastructure is asking drivers to take extra care on the TT course as workers repaint kerbs and bridges.
Contractors from Island Drainage & Groundwork will be working their way west from Ramsey from today, Thursday, April 16.
They're painting the traditional black and white racing marks on kerbs and the DOI says there may be temporary traffic lights and speed limits in some areas if needed.
And the department says where possible, they'll fit painting in with ongoing repairs around the course.
