Motorists using State Route 89A between Sedona and Flagstaff should allow extra travel time next week when the roadway is reduced to one lane near Slide Rock while a new cell tower is installed.

SR 89A will be narrowed to one lane between mileposts 381 and 384 from 7 a.m. to 5 p.m. Tuesday, December 13, and Wednesday, December 14. Flaggers will be on site to provide alternating north- and southbound travel through the work zone and delays are possible.

Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.

ADOT works to inform the public about planned highway restrictions and closures, but it’s possible that unscheduled impacts might occur because of weather or other factors.
