UPDATE( Aug. 7, 7:46 a.m.) -- The 80-acre Parley's Fire is believed to be human-caused, according to Utah Fire Info.
I-80 will closed at 9 a.m. between Foothill Drive and Parley's Summit. Eastbound and westbound lanes on I-80 will reopen at 9 p.m.
Alternate routes are I-84 near Ogden and Provo Canyon.
The blaze is zero percent contained and evacuations are still in place.
(Original report) -- Mandatory evacuations were ordered for residents of the Mt. Aire area after a fire broke out in Parley's Canyon on Thursday afternoon.
Residents were advised to "move immediately," according to the Unified Fire Authority.
The fire, named the Parleys Fire, is burning near Interstate 80 between the East Canyon and Mountain Dell exits. Interstate 80 was closed in both directions for approximately two hours, but reopened as of 9:30 p.m. The 132 and 134 off-ramps remain closed.
However, the interstate will closed again on Friday morning at 9 a.m., reporter Jim Spiewak is told. The closure will be in both directions, from Foothill Drive and I-215 to Parley's Summit. Officials did not provide an estimate of when the interstate would re-open on Friday.
The Utah Highway Patrol recommends drivers seeking an alternate route use I-84 and US-89 or US-40 and US-189 to get to the I-15 corridor.
"Please avoid the area," UFA says.
2News first learned of the fire just before 7 p.m. Thursday. By 7:18 p.m., it was estimated to have burned 40 acres. As of 8:30 p.m., the fire is 200 acres.
Reporter Brian Mullahy talked to a few people evacuating from Mt. Aire. Clint Chamberlain, who identified himself as a combat veteran, said he was not worried.
"I'm a combat vet — I feel like no one's shooting at us; it's fine. Hopefully it doesn't burn down and, if it does, we rebuild," Chamberlain said.
One concern: Mt. Aire Road is the only way in and out of the area, so if the fire were to jump the road, it could be bad, said resident Robert Stroud.
"If the fire jumps over the road, there's no way out ... you'd have to hike over Millcreek Canyon," Stroud said.
An evacuation center for the affected residents was established at Skyline High School, 3251 E. 3760 South.
