PHOENIX - Fire officials say I-17 remains closed in both directions as a result of a fast-moving wildfire.
According to BLM Arizona Fire officials, the Sunset Fire has burned an estimated 4,000 acres of land and is 20% contained.
About 130 fire personnel from across the Valley and over a dozen agencies were involved in battling the flames from the ground, as well as from the air.
"We had firefighters doing a burnout along the roadway, so we can protect the roadway and look towards opening I-17," said Dolores Garcia with the Bureau of Land Management.
Late Sunday night, ADOT officials say I-17 has been reopened in both directions.
At one point, the I-17 was closed southbound at milepost 259, while the northbound lanes were closed at milepost 248. Sunset Point was also evacuated as a precaution.
During the closure, drivers were forced to use alternate routes, which doubled river time and caused miles-long backups.
For one family, who was traveling from Prescott to Laveen, the worst part was sitting at a standstill in the extreme heat.
"It's just the aggravation," said Patrick Locke. "You know it's hot out and people were mad, and I was too."
Earlier reports from the Arizona Department of Transportation suggest that the brush fire sprouted from a vehicle fire.
