UPDATE: Wide-load restrictions and lane closures scheduled to begin May 29 on Interstate 15 in Arizona through Virgin River Gorge
Expect delays between Mesquite, Nevada, and St. George, Utah and a 224-mile detour for loads wider than 10 feet.

The Arizona Department of Transportation advises wide-load haulers and other drivers to plan for around-the-clock restrictions on I-15 through the Virgin River Gorge beginning Wednesday, May 29 and continuing through spring 2020. All loads wider than 10 feet must use a 224-mile detour route as crews repair three bridge decks along the narrow highway in northwestern Arizona. Other drivers should plan for delays and allow extra travel time while a section of I-15 is narrowed to one lane in each direction.

  • Wide-load detour: Signs will direct wide-load traffic to the detour route of US 93, Nevada State Route 319, and Utah State Route 56 between Las Vegas and Cedar City, Utah.
  • North- and southbound I-15 will be narrowed to one lane between mileposts 13 and 16.

Because of the terrain within the Virgin River Gorge and the narrow width of I-15, crews must reduce the width of travel lanes to 10 feet during construction. This will make I-15 impassible in the 3-mile work zone for vehicles wider than 10 feet. Crews will also move traffic over to one side of the highway while working on the other, providing one travel lane in each direction.

The $6.4 million project will rehabilitate three bridge decks on I-15. Work is scheduled to last at least one year.

Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
