Glendale, AZ – Around 5 a.m. Tuesday morning, Arizona Department of Public Safety troopers responded to a serious crash on the northbound lanes of Loop 101 Agua Fria near Union Hills Drive. The incident left a vehicle wedged in the underpass, prompting an immediate shutdown of that portion of the freeway.

Emergency response and injuries

First‑on‑scene troopers confirmed that multiple people sustained serious injuries, though the exact number of victims has not yet been released. Firefighters arrived quickly and began cutting sections of the damaged vehicle to reach those trapped inside. Traffic cameras captured the scene, showing emergency crews surrounding the wreck and working to extricate the occupants.

Impact on traffic

With the northbound lanes closed, drivers are experiencing significant delays. The Arizona Department of Transportation advises motorists to use alternate routes, such as the nearby Loop 202 or surface streets, until the underpass can be cleared and the freeway reopened. Southbound traffic on Loop 101 remains unaffected at this time.

What residents should know

There is currently no estimated time for the reopening of the northbound lanes. Glendale officials are monitoring the situation and will provide updates as soon as they become available. Residents who need to travel through the area are encouraged to check real‑time traffic alerts on the ADOT website or local news outlets.

Community safety reminder

Incidents like this underscore the importance of safe driving, especially during early‑morning hours when visibility can be reduced. Glendale police continue to urge motorists to obey speed limits, avoid distractions, and stay alert for construction or emergency zones on the roadways.
