The Broad Fire in Weber Canyon reached 50% containment Sunday evening, Sept. 6, holding steady at 134 acres after burning through brush and timber on both sides of Interstate 84 over the Labor Day weekend.

Fire managers opened both westbound lanes on I-84 to handle holiday traffic Monday, Sept. 7, though the shoulder remained closed, Utah Fire Info said on X. Both eastbound lanes were scheduled to reopen at 8 p.m. Sunday. The interstate had been fully closed Saturday, Sept. 5, when the fire ignited around 12:40 p.m. and jumped the highway.

The fire grew quickly Saturday but slowed Sunday as clouds and cooler temperatures moved in. U.S. Forest Service Public Information Officer Sierra Hellstrom told the Standard-Examiner that overnight temperatures Saturday never dropped below 70 degrees, keeping fire activity high through the night.

"We woke up to smoke coming off of the mountain this morning and night shift did say that there was fire and visible flames throughout the entire evening," Hellstrom said Sunday.

By Sunday afternoon, containment stood at 10% on the south side of I-84 in Davis County near the Weber River. Four crews were working the mountain, supported by aircraft. By Sunday evening, that figure rose to 50% after what Utah Fire Info credited to long shifts by firefighters and pilots.

Containment lines held on the south and west sides of the fire, closest to I-84 and the community of Uintah. The north side remained active Monday, with fire burning slowly through underbrush and trees.

No evacuations were ordered. No one was injured by the fire itself, Hellstrom said.

Rocky Mountain Power transmission lines and Union Pacific Railroad lines through Weber Canyon were the only major infrastructure in the fire's immediate path, according to the Standard-Examiner.

The cause remains under investigation. Hellstrom said Sunday that crews expected to work the fire for at least two to three more days.

Utah Fire Info urged drivers to slow down near the fire area, noting crews had seen close calls with motorists distracted by firefighting aircraft. Residents can report wildfires by calling 911.
