US 89 will be narrowed to one lane south of the SR 64 Junction to Sunset Crater Rd (milepost 462 to 443) on Monday (Aug. 3) and Tuesday (Aug. 4) from 6 a.m. to 6 p.m. The pavement marker installation work will be a moving operation, utilizing a three-mile restriction. The restriction is required to allow Arizona Department of Transportation crews to install pavement markers on the roadway.

During installation, delays of up to 15 minutes can be anticipated. A pilot car will allow for alternating travel through the work zone. Please allow for extra travel time during construction and be alert while traveling through the work zone.
