Mount Lemmon Highway will close intermittently Thursday and Friday for the filming of a TV commercial.
U.S. Forest Service representative James Sutton said the closures will last between 10 and 20 minutes. He expects the closures to go from 11 a.m. to 8 p.m. both days.
Motorists who want to get up the mountain quickly should go up before 10 a.m., he said.
