A man has died following a single-car crash that shut down Mill Avenue in both directions near 13th Street early Saturday morning, just steps from ASU Gammage on the southern edge of downtown Tempe. First responders were called to the scene around 4 a.m., and the driver was rushed to a hospital with serious injuries before later dying from his wounds.
According to AZ Family, Tempe police say officers who arrived at the scene found the car's driver seriously hurt, and detectives are now working to determine what led to the crash. As reported by 12News, the crash happened at approximately 4 a.m. Saturday, prompting collision investigators to close Mill Avenue in both directions near 13th Street while they processed the scene. Drivers have been urged to avoid the area while the investigation continues.
A Corridor With a History of Serious Wrecks
This isn't the first time this stretch of Mill Avenue has seen a severe single-vehicle crash. Emergency crews responded to nearly the same location in early April, when a vehicle struck a Valley Metro streetcar power pole and caught fire just after 11:10 p.m., sending the driver to the hospital in serious condition, per a report from Key News Network. That stretch of roadway carries the $192 million Valley Metro Streetcar system, which runs along a three-mile track through downtown Tempe and past 13th Street, sharing right-of-way and utility infrastructure with vehicle lanes, according to trade outlet Rocky Mountain Construction. It remains unclear whether any streetcar or utility infrastructure was involved in Saturday's crash.
The location sits at a transition point where the dense, high-traffic nightlife district of downtown Mill Avenue meets the southern edge of Arizona State University's campus near ASU Gammage. That mix of foot traffic, nightlife crowds, and vehicle lanes has made the corridor a repeated focus of city safety efforts in recent years.
Tempe's Push to Curb Speeding and Crashes
Tempe has taken several steps aimed at reducing crashes like this one. The Tempe City Council voted in June to lower speed limits along seven key road corridors citywide as part of an effort to decrease severe and fatal collisions, according to the Tempe Independent. The Tempe Police Department also launched targeted traffic enforcement operations in downtown Tempe along Mill Avenue in April to curb excessive speeding and dangerous driving, as reported by AZ Family.
The city has additionally rolled out photo-enforcement cameras at high-crash intersections, including along Mill Avenue at Baseline and Southern avenues, per KTAR News. Those camera locations were chosen because they had recorded at least three severe or fatal crashes between 2018 and 2022, the outlet reported. Tempe has described itself as the first Arizona city to adopt a Vision Zero policy, a framework aimed at eliminating all traffic fatalities and serious injuries through data-driven street design, according to the City of Tempe, which also rotates safety corridors quarterly based on collision data.
Statewide Numbers Underscore the Stakes
The crash adds to a grim statewide picture. Arizona recorded 1,180 traffic deaths across 1,063 fatal collisions in 2023, following 1,294 fatalities the year before, according to data reported by the Bleaman Law Firm citing the Arizona Department of Transportation. Excessive speed remains a factor in roughly 35% of all fatal traffic crashes statewide, making it the single leading contributing factor in fatal collisions in Arizona, per ADOT's annual Crash Facts report as cited by Wyatt Injury Law.
It is not yet known whether speed, mechanical failure, a medical emergency, or impairment played a role in Saturday's crash, and Tempe police detectives are still working to determine what caused it. Mill Avenue near 13th Street has also been the subject of ongoing streetscape work, after Hoodline detailed closures tied to gateway signs installed as part of the city's Downtown Tempe Refresh project last year. No further details about the identity of the man who died have been released.
