Some work to be done early in the morning
Motorists are being urged to be on the lookout for Department of Infrastructure staff while they're out on the Island's roads.
The warning comes as they continue to remove Festival of Motorcycling-related equipment and replace 'road furniture' removed for the event.
The department says staff and contractors will be carrying out this work on the TT course and diversionary routes until around this coming weekend.
Some of the work is due to be done early in the morning before commuter traffic builds up.
Today is due to be particularly busy, according to the DoI - speed limits which have been changed will revert back to normal, roundabouts and pedestrian refuges replaced, and temporary one-way systems and no parking areas removed.
