Tempe’s Most Dangerous Intersections and Crash Corridors
Baseline Road & I-10 (Tempe’s Highest-Crash Intersection)
Baseline Road and I-10 ranked #68 out of the 100 highest crash-risk intersections tracked by MAG across Maricopa County. There were 257 crashes recorded between 2018 and 2022, which had the highest raw crash count of any Tempe intersection on the list. This high-speed freeway merging and exiting traffic with cross-traffic on Baseline Road feeding into and out of Arizona Mills and other nearby businesses, a combination that produces frequent and often severe collisions.
Broadway Road & Price Road
This intersection was ranked #31 in the MAG Top 100 with 144 crashes over the same five-year period. Many of the east/west roads intersecting up and down Price Road are busy and potentially dangerous. But Broadway Road and Price Road is one of Tempe’s busiest crossings. Heavy commuter and commercial traffic moving between Tempe, Chandler, and Mesa converge here throughout the day, creating a consistent crash pattern.
Baseline Road & Kyrene Road
This intersection forms a “T” junction, with Kyrene Road running south and terminating at Baseline Road. Ranking #78 among Maricopa County’s most dangerous intersections, it recorded 124 crashes between 2018 and 2022.
Its high collision rate stems from a volatile mix of regional and local traffic. Situated just one mile east of the heavily congested I-10 freeway junction, westbound Baseline Road frequently experiences sudden, stop-and-go backups right at Kyrene. Compounding this risk are the wide turning movements from local retail centers and the direct intersection with the Western Canal Multi-use Path, which introduces a constant stream of pedestrians and cyclists into a high-speed vehicle conflict zone.
Elliot Road & Kyrene Road
Ranked #58 with 98 crashes, this intersection reflects the mixed residential and commercial character of southwest Tempe. Kyrene Road carries steady north-south traffic that intersects with Elliot Road’s east-west commuter flow, a pattern that shows up consistently in Tempe’s crash data. A lot of traffic flows through this intersection from busy commercial areas, including Costco and the Walmart Supercenter.
Broadway Road & Hardy Drive
Ranked #62 with 65 crashes, the intersection of Broadway Road and Hardy Drive demonstrates that lower speed limits do not always mean lower risk. Because Hardy Drive serves as one of Tempe’s designated “Handlebar” bicycle routes and sits in close proximity to Tempe High School, this intersection sees a highly volatile mix of car, bicycle, and pedestrian traffic. The intersection is particularly prone to frequent turning and crossing conflicts during morning and afternoon school drop-off windows, when heavy student foot traffic layers directly on top of regular commuter congestion.
Mill Avenue: A Different Kind of Danger
Mill Avenue near Arizona State University presents a crash risk profile unlike anywhere else in the East Valley. Restaurants, bars, retail, and ASU foot traffic bring a dense mix of pedestrians, cyclists, rideshare pickups and drop-offs, and through traffic into the same few blocks, especially at night. Tempe’s own Vision Zero data shows that 30 percent of serious injury and fatal crashes in the city between 2021 and 2024 involved pedestrians, bicyclists, e-bikes, or scooters. A fatal bicycle crash on February 14, 2023 at College Avenue and Alameda Drive, where a cyclist failed to stop at a four-way stop, is a reminder of how quickly this corridor can turn dangerous. Late-night impaired driving crashes are a regular occurrence here as well, and Tempe recorded 319 DUI-related crashes in 2023, with DUI fatalities rising sixfold over the prior year.
Loop 101 & Loop 202 Interchange & University Drive Ramps
This mile-long stretch compresses the Loop 101 (Price Freeway) and Loop 202 (Red Mountain Freeway) system interchange right up against the University Drive on-ramps and off-ramps, creating one of Tempe’s most chaotic weaving zones. Drivers entering the freeway at University Drive have to accelerate hard and cross several lanes to the left, at the same moment high-speed through traffic is cutting right to exit at University Drive or peel onto the eastbound and westbound Loop 202 flyovers. That kind of compressed, high-speed weaving catches distracted and reckless drivers off guard. It is a consistent source of serious freeway crashes.
Loop 101 and US-60 Interchange
Just before Loop 101 crosses into Chandler, it meets US-60 (Superstition Freeway) at a multi-level interchange near Exit 55AB. Traffic backs up trying to merge onto US-60 in both directions, northbound and southbound alike, while through traffic in the other lanes keeps moving at freeway speed. That combination leads to rear-end crashes and drivers making sudden lane changes into harm’s way.
Crashes occurring on Tempe freeways and major intersections range from fatal and serious injuries, including traumatic brain injuries, fractures, debilitating neck and back and other life altering injuries.
