ARIZONA STRIP – Crews continue to repave a 16-mile segment of Interstate 15 in northwest Arizona this weekend and into next week, according to the Arizona Department of Transportation.

Drivers can expect the following:

Work hours will be 4 p.m. to noon the next day, MST, seven days per week.

  • A single-lane closure will be in effect 24 hours per day through each work zone, which will allow crews to remove old pavement and apply new pavement more efficiently.
  • Saturday and Sunday, Sept. 15-16 – Crews will repave the both the northbound Black Rock on-ramp and off-ramp, requiring the closure of the ramps during work hours.
  • Sunday through Friday, Sept. 16-21 – Crews will repave the southbound right lane, which will be closed 24 hours per day.
  • Tuesday and Wednesday, Sept. 18-19 – Crews will repave both the southbound Black Rock on-ramp and off-ramp, requiring the closure of the ramps during work hours.

The work zone will be clearly marked by temporary barricades and signage. ADOT advises drivers to allow additional time to reach their destinations and to proceed through the work zone with caution, comply with the reduced speed limit of 45 mph, and be alert for construction equipment and personnel.

The $11.6 million project, which is scheduled for completion by the end of October, includes removal of a layer of the existing pavement and repaving the roadway from the Virgin River Gorge to the Utah State line (mileposts 13-29).

Individuals seeking to avoid the repaving work in the Virgin River Gorge are advised to take Highway 91 as an alternate route. The highway bypasses the gorge entirely. Southbound travelers will reconnect with I-15 at  Littlefield, Ariz, while northbound travelers will follow the route into Santa Clara and then St. George via Sunset Boulevard.

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.
