US 89 narrowed to one lane north of the Gap and south of SR 64 Junction beginning Monday

US 89 will be narrowed to one lane north of the Gap and south of the SR 64 Junction in Cameron (milepost 510 to 460) from today to Friday 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.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
