A brush fire caused delays for several hours on the northbound lanes of Interstate 17 north of the Valley on Monday morning, authorities said.
Traffic was backed up around 11 miles between Black Canyon City and Bumble Bee beginning at 10:15 a.m., according to the Arizona Department of Transportation (ADOT).
The delays were cleared by 2:15 p.m. The fire started near I-17 around Sunset Point, which is 55 miles north of downtown Phoenix. The fire began when a pickup truck towing a gooseneck flatbed trailer loaded with construction supplies overheated at milepost 250 around 7:45 a.m., according to the Arizona Department of Public Safety (DPS).
The truck driver pulled off to the right side of northbound I-17. After that, a fire ignited under the hood of the pickup truck, DPS said.
