PHOENIX - The 303 Fire was contained Thursday at about 6 p.m. after burning about 1,200 acres, Phoenix Fire Department officials said.

Closures from the fire affected four freeways, but when westbound Loop 303 reopened around 9 p.m., all the roadways were back open after the blaze.

Both directions of Interstate 17 were shut down in north Phoenix due to heavy smoke from the wildfire, according to the Arizona Department of Transportation.

Southbound I-17 was closed at the Carefree Highway and northbound was shut down at Loop 101.

The brush fire also closed Loop 303 westbound at I-17, ADOT said.

Both transition ramps from Loop 101 to northbound I-17 were closed, as was SR 74 eastbound at Lake Pleasant Parkway.

According to authorities, more than 100 people worked to put out the blaze. They used three air tankers and a lead plane to attack the fire from above.

The fire stopped at or before reaching I-17, Loop 303, and Carefree Highway. The fire never jumped any freeway.

Fire crews, including BLM and hotshots, will continue to mop up and work at night.

Phoenix FD first responded to the scene and called for additional support from State Fire and BLM. Crews worked to establish cut off points for the fire, Phoenix FD said.

No first responders were injured in this fire, Phoenix Fire Department officials said.

The brush fire was first reported just before 1 p.m.
