A semi-truck hauling trash overturned on southbound Loop 303 near Grand Avenue shortly before 7 a.m. Thursday, spilling its load across the freeway and triggering a major traffic backup for West Valley commuters heading toward Sun City West. The driver was hospitalized with minor injuries following the crash, which also involved a passenger vehicle.
According to AZ Family, the Arizona Department of Public Safety said the semi-truck was carrying trash when it overturned, spilling its load all over the freeway. Traffic cameras captured large bits of debris and trash scattered across the roadway in the crash's aftermath, turning the normally routine morning commute into a slow crawl for drivers trying to get around the mess.
Telemundo Arizona placed the time of the crash slightly earlier, reporting it occurred around 6:44 a.m. and describing the overturned vehicle as a garbage truck that collided with a passenger vehicle. The station reported that southbound lanes remained restricted because of garbage and debris scattered across the roadway, echoing the scene described by AZ Family's cameras near the crash site.
Shoulder Becomes Lifeline for Stuck Drivers
With the southbound lanes of Loop 303 effectively shut down near Grand Avenue, traffic was getting through only on the shoulder, according to the report from AZ Family. The chaos wasn't confined to one direction either — the northbound left lane was also blocked as crews worked the scene, compounding delays for drivers on both sides of the freeway.
Drivers were urged to expect heavy delays or avoid the area entirely while crews cleared the wreckage and the scattered trash from the roadway. The spill effectively shut down an entire stretch of the West Valley freeway during the morning rush, leaving commuters searching for alternate routes around Sun City West.
Not the Only Recent Rollover on Arizona Highways
The Loop 303 crash comes just days after a separate semi-truck rollover in Chino Valley triggered a hazmat response after crews found powder scattered across that scene, as reported by azcentral.com. While that incident involved an unknown powdery substance rather than trash, it marks a second large commercial truck rollover on Arizona roads within the span of a week.
No further details on when the Loop 303 lanes fully reopened or how long cleanup efforts took have been released. The identities and condition of the occupants in the passenger vehicle involved in the crash also have not been disclosed.
