 but the cause is still under investigation. Meanwhile, a brush fire about 10 miles from Prescott caused headaches for drivers due to a closure of part of Interstate 17. The Perry Tank Fire caused the closure of the highway in both directions yesterday afternoon. Traffic was rerouted to Bloody Basin Road. The northbound lanes were reopened a few hours later, but the southbound lanes remained closed until 9 last night. The fire grew to around 200 acres, and the Bureau of Land Management Resources responded near Black Canyon City. The cause of the fire isn't known at this time.
