A lightning-sparked wildfire was moving quickly through dry vegetation in Box Elder County on Friday, getting close enough to Interstate 84 that state officials shut down a 32-mile stretch of the road between Tremonton and Snowville near the Idaho border.

Officials announced the roadway was closed in both directions about 7:30 p.m. It’s unclear when the highway will reopen, and a fire spokesman told The Salt Lake Tribune it’s possible that wind could propel blaze — dubbed the Goring Fire — across the road.

Division of Forestry, Fire and State Lands spokesman Jason Curry said the fire grew rapidly, burning at least 7,000 acres Friday. It was completely uncontained .

Curry said the fire is threatening ranch homes in the area, but officials haven’t called for residents to evacuate.

State and county fire crews have been fighting the fire.
