U.S. 6 remained closed through Spanish Fork Canyon on Monday after the Coal Hollow Fire jumped the highway and forced the evacuation of Diamond Fork Canyon.
According to fire officals, the fire — which was sparked by lightning on Aug. 4 — is becoming established in the Uinta-Wasatch-Cache National Forest. As of Monday morning, it is 4 percent contained and is estimated to have burned 20,352 acres.
U.S. 6 was closed Sunday when the fire crossed it. It remains off limits to traffic from Diamond Fork to Tucker — mile markers 187-203.
The Utah Department of Transportation advised eastbound motorists to use southbound I-15 to US-50 in Scipio to eastbound I-70 as an alternate route, and westbound drivers to use westbound I-70 to US-50 in Salina to northbound I-15.
