SPANISH FORK, Utah -- The Coal Hollow Fire jumped U.S. Highway 6 Sunday night, forcing a new round of evacuations and the closure of the highway in both directions in Spanish Fork Canyon.
As of around 9:30 p.m. Sunday, Highway 6 is closed from Diamond Fork to Tucker, which are mile markers 185 through 203.
All of Diamond Fork is evacuated up to Springville crossing and east to Sheep Creek Road, according to the sheriff's office, which says those evacuations are likely to remain in effect through at least later Monday.
The post said the fire had jumped the highway around the Narrows.
Around 4:30 p.m., the Utah Department of Transportation, the Utah County Sheriff's Office and Utah Fire Info all tweeted that U.S. Highway 6 was closed in both directions from mile post 187 at the Thistle Junction with U.S. Highway 89 to mile post 203 which is near the Tucker/Skyline Drive area.
Firefighters wanted to keep the fire from crossing U.S. Highway 6, but weren't surprised it did because of all of the dry fuels and erratic winds and unstable atmosphere in the area.
UDOT suggests using I-70 as an alternate route, which could add one hour or more to normal travel times.

Trains that run in Spanish Fork Canyon have been shut down and rail crews report that power line poles are actively burning.
"If them lines come down, it's going to take a long time to get 'em across," Operations Section Chief Rob Powell said. "I would expect probably several days, so make plans accordingly."
The road closure was announced about an hour after Utah Fire Info reported extreme fire activity was picking up with the Coal Hollow Fire near Highway 6 and that visibility was becoming very limited.
The Coal Hollow Fire grew 7 percent overnight and had burned over 19,000 acres as of Sunday morning and was 4 percent contained.
