ADOT is planning for daytime lane restrictions on US 89 near Cameron, 50 miles north of Flagstaff beginning Tuesday from 8 a.m. to 4 p.m. The restrictions will be between milepost 471 and 473, with 89 narrowed to one lane of alternating north and southbound traffic. The restrictions are needed so crews can perform maintenance to the highway. The lane restrictions are expected to be lifted on Thursday. ADOT reminds motorists to slow down and use caution when traveling near crews and equipment.
