Mesa’s Most Dangerous Intersections and Crash Corridors
Dobson Road & University Drive (Mesa’s Most Dangerous Intersection)
The intersection of Dobson Road and University Drive is one of Mesa’s most dangerous crossings, ranking #86 on the Maricopa Association of Governments (MAG) Top 100 Crash-Risk Intersections. A staggering 75 collisions were recorded over a five-year window, many involving serious injuries and significant damage. The high crash volume stems from its central location near the bustling Asian District, Mesa Community College, and Banner Desert Medical Center. The intersection is flooded with heavy daily traffic.
The primary hazard at this intersection is left-turn crashes. With multiple lanes of traffic moving at different speeds, drivers get impatient, panic, or misjudge their gap and turn in front of oncoming vehicles. This leads to high-severity T-bone collisions, and unfortunately, some of these crashes result in catastrophic injuries and deaths. Bicyclists and pedestrians add another layer of risk, especially during Arizona’s cooler months when foot and bike traffic through the intersection increases.
The intersection’s dangerous reputation is underscored by a history of severe incidents, including a fatal pedestrian crash and a high-profile DUI hit-and-run in which the driver fled the scene leaving three young children in the car.
8th Avenue & Alma School Road
Sneaking onto the regional watch list at #100 in the MAG Top 100, this intersection recorded 49 crashes during the same tracking period. Located in Mesa’s Kleinman Park neighborhood near downtown, this corridor blends a dense matrix of local shops and residential traffic, anchored by the Food City-anchored 8th Avenue Shops center. Multiple lanes bring together a steady mix of vehicles, bicycles, and pedestrians moving through the intersection, and that mix, combined with heavy local shop traffic, generates a high frequency of sudden stops, improper lane changes, and turning-movement collisions throughout the day.
US-60 (Superstition Freeway)
Beyond local intersections, US-60 (the Superstition Freeway) serves as one of the most hazardous freeways cutting through the center of Mesa. The danger stems primarily from a traffic volume that has outgrown what the US-60 was built to accommodate. As Mesa and surrounding communities have expanded, this freeway has been put under immense strain, forcing high-speed traffic to abruptly transition into stop-and-go commuter gridlock. This is particularly true around the Loop 101 transition and between the Country Club Drive and Power Road exits, with additional trouble spots at the Alma School, Stapley, Gilbert Road, and Superstition Springs interchanges
When a significant volume of traffic traveling at high speeds is forced to come to abrupt stops, bad collisions can happen. Extreme speed differentials develop across lanes; some vehicles come to a complete standstill while adjacent lanes attempt to maintain a 65 MPH pace. This dynamic triggers high-impact, multi-vehicle pileups and severe rear-end collisions that result in far more catastrophic injuries than low-speed surface street accidents. Furthermore, complex interchange bottlenecks at the Loop 101 and Loop 202 junctions force erratic, last-second lane changes and blind-spot sideswipes as drivers aggressively fight to merge.
Loop 202 (Red Mountain Freeway)
Further north, Loop 202 wraps around the north-end of Mesa before curving south into the Santan Freeway. It carries lighter traffic than the US-60 or I-10, but its sweeping curves and long straightaways invite higher speeds. Further north, Loop 202 (the Red Mountain Freeway) wraps around Mesa before curving south into the Santan Freeway. It carries lighter traffic than the US-60 or I-10, but its sweeping curves and long straightaways invite higher speeds.
As the freeway rises onto the elevated ridge near Greenfield Road, above the Spook Hill area and the Fannin-McFarland Aqueduct, the terrain drops away and opens a wide western view: Camelback Mountain to the northwest, and the Papago Buttes and downtown Phoenix skyline to the far west, with Red Mountain standing to the north. It is one of the more scenic stretches in the East Valley, and like any view that pulls a driver’s eye off the road, it rewards attention.
The real danger on this loop is concentrated at its interchanges, most notably the SuperRedTan Interchange, where Loop 202 meets the US-60. This multi-level junction connects Mesa commuters to Tempe, Chandler, and Gilbert, forcing high-speed weaving at 65-plus MPH. Rapid lane-shifting and blind-spot sideswipes make it highly prone to violent collisions, and when traffic backs up at rush hour, the jump from open-freeway speeds to a standstill regularly sets off multi-vehicle pileups.
Pedestrian and Bicycle Risk Along Mesa’s Roadways
Bicycle and pedestrian crashes remain a serious problem in Mesa despite the city’s investment in multi-use pathways. Vulnerable road users made up more than a third of the city’s traffic fatalities in 2023: 9 pedestrian and 7 bicyclist deaths out of 45 total, per the city’s own crash report. These crashes cluster on Mesa’s arterial roads, where high-speed vehicle traffic crosses paths with people on foot or on a bike, and the most common patterns are drivers making turning movements at intersections and pedestrians or cyclists crossing outside marked crosswalks. The Dobson Road and University Drive corridor near Mesa Community College is a clear example: heavy student foot and bike traffic funnels through the same intersection carrying some of Mesa’s highest vehicle volume, and right-turn crashes involving pedestrians and cyclists are a recurring pattern there. Corridors near other colleges, transit stops, and dense commercial strips see similar risk, since that’s where foot and bike traffic is heaviest right at the points where turning vehicles are most active.
Canal Path Crossings
Mesa’s canal system, including the paths along the Consolidated Canal and Eastern Canal, gives cyclists and runners a vehicle-free route through much of the city, but that changes wherever a trail meets a major road. At those crossings, trail users have to step off the path and onto the street, often without a signal or marked crosswalk. Riders and pedestrians who have grown used to a car-free trail can be caught off guard by fast-moving arterial traffic at these gaps, so extra caution is warranted anywhere a shared-use path crosses a multi-lane road.
Crashes occurring on Mesa freeways and major intersections range from fatal and serious injuries, including traumatic brain injuries, fractures, debilitating neck and back and other life altering injuries.
