11/4/15 - A jackknifed semi-truck blocked three lanes along westbound Interstate 10 in Phoenix shortly after 6 a.m Wednesday, officials said.
The crash occurred between 32nd Street and the Interstate 17 split and backed up traffic more than a mile.
An Arizona Department of Public Safety spokesman said the collision caused the semi-truck to leak fuel.
DPS crews were working to clear the roadway. The Arizona Department of Transportation advised drivers heading to Phoenix and the West Valley to take alternate routes.
