US 89 will be narrowed to one lane with alternating access for both directions between the Arizona/Utah state line to just south of the Bitter Springs Junction at US 89A (milepost 556 to 517) from Tuesday (July 21) to Friday (July 22) from 7 a.m. to 5 p.m. 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.
