U.S. Highway 6 in Spanish Fork Canyon remained closed Monday due to fire activity from the Coal Hollow Fire.

The wildfire crossed the highway Sunday afternoon, and by Monday morning, officials report that the fire burned 20,352 acres. The U.S. Forest Service is reporting 4 percent containment of the fire.

“It is unclear at this time how long the highway road closure will be in place, but fire officials stressed that travel along the highway during this time could endanger public safety,” the Forest Service wrote in a press release.

Crews monitored the fire throughout the night after it moved south of U.S. 6 for the first time, according to the Forest Service.

U.S. 6 is closed in both directions from the U.S. Highway 89 junction to milepost 203, in the Tucker area.

This is the second highway closure in less than a week. On Thursday, officials closed U.S. 6 for about two hours when parts of the fire primarily burning southeast of the U.S. 6-U.S. 89 junction moved within 100 yards of U.S. 6.

Evacuations and pre-evacuations from Sunday remain in place, including a pre-evacuation order for Diamond Fork Canyon that was put in place Sunday evening, according to the U.S. Forest Service.

The Union Pacific Railroad has also been closed through Spanish Fork Canyon, according to the Forest Service.

Firefighters in several areas around the fire are working to improve firelines, according to the U.S. Forest Service, and more helitack crews will be arriving Monday.

Measurable rainfall is expected Monday with incoming thunderstorms, and the U.S. Forest Service reports debris may be picked up by winds, causing ash to fall in areas near the perimeter of the fire.

“Inversions will be weak due to the overnight cloud cover and added humidity, lifting early in the day,” the Forest Service wrote in a press release.

The Utah Department of Environmental Quality reported Monday morning that smoke levels were rising Monday morning in southern Utah County, but that they expected smoke levels to decrease by noon.
