The Department of Infrastructure says part of the TT course will have temporary traffic lights today during emergency work.
Repairs to a sunken drain means Main Road in Crosby will have the lights near Kissack Lane, near the Co-op bus stop.
The nearby pedestrian crossing will also be out of action while the work takes place.
The DOI says the lights will be in place until 3.30pm.
