Truck dumps load of gravel on I-17 in north Phoenix, causing delays

PHOENIX (3TV/CBS 5) -- Interstate 17 in north Phoenix returned to normal on Thursday afternoon, hours after a crash caused a dump truck to spill gravel on the freeway. According to the Department of Public Safety, it appears a semi-truck driver heading south may have hit a red pickup truck near Deer Valley Road around 11:30 a.m. The semi-truck rolled and spilled a large amount of gravel, forcing the closure of all but one lane. There weren’t any serious injuries, but it created a huge backup for drivers trying to get into the Valley. DPS said there was a second crash involving four vehicles in the backup, but no one was seriously hurt.
