PHOENIX -- A rollover accident on eastbound Interstate 10 at 24th Street Wednesday closed all but the emergency lane and created a 43-mile logjam over three freeways.
The mess lasted for five hours hours, finally clearing around 11 a.m.
Commuter traffic was delayed after a flatbed truck carrying mulch flipped over, spilling its load, affecting traffic on Interstate 17 and State Route 51.
Traffic on I-10 was pushed back 13 miles. Some cars managed to sneak past using the shoulder.
The backup also spilled over onto southbound I-17, with a 17-mile ribbon of brake lights snaking from the closure to Bell Road.
The Piestewa Freeway was tied up for 13 miles.
By 10 a.m. two lanes were open on I-10.
