I-15 work between Mesquite, Utah forces 224-mile detour for some

Updated May 8, 2019 - 9:32 pm

After a brief reprieve, some motorists traveling on Interstate 15 between Mesquite and St. George, Utah, can expect to take a 224-mile detour starting at the end of the month during a yearlong road project.

Wide-load restrictions and lane closures planned as part of a $6.4 million bridge deck repair project on I-15 through the Virgin River Gorge had been slated to start in April but now will kick off on May 29 and last through spring 2020, the Arizona Department of Transportation announced Wednesday

The delayed start date was caused by permitting delays pertaining to setting up detour signage in Utah and Nevada, according to Ryan Harding, ADOT spokesman. ADOT also requires detour warning signs to be in place two weeks before the start of a work project.

All vehicles carrying loads wider than 10 feet must use a 224-mile detour route as crews carry out the repairs along the narrow highway, which will be reduced to one lane in each direction, in northwestern Arizona. Other drivers should plan for delays and allow extra travel time because of the narrowing of lanes between mileposts 13 and 16, ADOT said.

Wide-load traffic will be detoured to a route consisting of U.S. 93, State Route 319 and Utah State Route 56 between Las Vegas and Cedar City, Utah. Motorists will pass through Crystal Springs and Panaca on the route.

Because of the terrain within the Virgin River Gorge and the narrow width of I-15 in the area, crews must reduce the width of travel lanes to 10 feet during construction. That will make travel in the 3-mile work zone impassible for vehicles wider than 10 feet.

Crews will divert traffic over to one side of the highway while working on the other, providing one travel lane in each direction.
