Phoenix’s Most Dangerous Intersections and Crash Corridors
Tatum Boulevard & Shea Boulevard (Northeast Phoenix)
Where Northeast Phoenix meets Paradise Valley, the intersection of Tatum Boulevard and Shea Boulevard carries three through lanes in each direction on both streets, with double left-turn lanes at the signal and a dedicated right-turn lane from Shea onto Tatum. Posted speeds of 45 mph, combined with the intersection’s width and turning movements, create a corridor where misjudged gaps and red-light entries turn into high-speed, high-impact collisions rather than minor fender benders. Just north along Tatum at Desert Cove Avenue, the corridor also serves as a dense access point for medical offices like Camelback Women’s Health, senior living communities such as Desert Bloom Assisted Living, and a retail cluster anchored by Target, Kohl’s, Marshalls, HomeGoods, and Old Navy, all of which mean more cars turning and merging across lanes that are already moving fast.
The corridor’s crash history reflects that volatility. In recent years, this stretch has seen a fatal red-light collision with a rideshare vehicle at the main intersection, and a separate crash just up the road at Desert Cove Avenue that sent a vehicle into a group of pedestrians, leaving several with critical injuries.
Cave Creek Road & Greenway Parkway (North Phoenix)
While many hazardous intersections earn their risk status through sheer collision volume, Cave Creek Road and Greenway Parkway tells a different story, one driven by severity rather than frequency. Ranking 32nd on MAG’s crash-risk list despite just 90 total crashes over five years, this North Phoenix crossing carries a disproportionately high risk score, because MAG’s scoring weighs severe and fatal collisions far more heavily than minor fender benders.
That severity has a documented pattern: drivers turning left from Cave Creek Road onto Greenway Parkway have repeatedly misjudged gaps in oncoming traffic, striking motorcyclists and cyclists traveling northbound. Fatal collisions matching this exact pattern have occurred here in 2019, 2024, 2025, and again in 2026. In response, the City of Phoenix has approved safety upgrades for this intersection, including new traffic signal equipment, refreshed lane striping, and ADA-compliant crosswalk ramp upgrades.
48th Street & Chandler Boulevard (Ahwatukee)
Located in the Ahwatukee Foothills area near Interstate 10, the intersection of 48th Street and Chandler Boulevard ranks #15 on the MAG High-Risk Intersections list with 103 recorded collisions. Because of its crash history, including at least one documented fatality, it has been formally designated as part of Phoenix’s official Vision Zero High Injury Network, one of the few Ahwatukee intersections to carry that designation. Serving as a key arterial connection to I-10 and surrounding shopping centers, this corridor carries heavy daily commuter traffic.
Left-turn collisions are a recurring hazard here. High vehicle speeds along Chandler Boulevard make judging gaps in oncoming traffic difficult, particularly during rush-hour sun glare and evening commutes. When drivers misjudge oncoming speeds while attempting unprotected left turns, the resulting broadside collisions often produce severe, life-altering injuries.
32nd Street & Camelback Road (Biltmore)
Like the Northeast Phoenix corridor near Paradise Valley, the Biltmore area doesn’t generate the raw crash volume of Phoenix’s west-side arterials, but 32nd Street and Camelback Road still carries serious daily risk. The intersection sees roughly 57,000 vehicles a day on Camelback Road and 36,000 on 32nd Street, a heavy volume moving through one of the city’s more affluent commercial and residential corridors.
That volume has produced real tragedy. This intersection has seen pedestrian fatalities tied to left-turn collisions, the same dynamic that drives so much of the serious crash activity across Phoenix’s busiest crossings. The Biltmore area’s mix of hotel, office, and retail traffic converging with residential cross-traffic creates constant turning conflicts, even without the sheer collision counts seen on the city’s west side.
27th Avenue & Camelback Road (Central Phoenix)
At 27th Avenue and Camelback Road, near Grand Canyon University, heavy traffic and heavy pedestrian activity collide to create one of the most hazardous crossings in the Phoenix metro area. The intersection recorded 210 crashes over MAG’s five-year tracking period, and city traffic engineers have specifically flagged it for a high concentration of pedestrian collisions within 500 feet of its crosswalks. The danger extends well beyond the intersection itself: 27th Avenue as a whole is cited as the fourth-worst street in the nation for pedestrian deaths, and a Phoenix New Times analysis of 25 years of federal crash data found 118 pedestrians killed along this corridor since 2000, more than any other stretch of roadway in Arizona.
Heavy Valley Metro bus ridership along Camelback Road brings a steady stream of pedestrians through the intersection, many of whom must cross multi-lane, high-speed arterial traffic to reach their stops. That risk led the City of Phoenix to select this exact intersection as one of ten locations for its “Heads Up! Walk Smart” safety campaign, aimed at educating both drivers and pedestrians on mid-block crossings, failure-to-yield turns, and visibility hazards.
Baseline Road (South Phoenix)
Baseline Road cuts across the length of South Phoenix as a wide, high-speed arterial with too few bike lanes and minimal marked crossings, conditions that create serious risk for drivers, bicyclists, and pedestrians alike.
7th Avenue and Baseline Road illustrates the pattern. The intersection ranks #47 on MAG’s Top 100 Intersections by Crash Risk, with 119 recorded collisions over the five-year tracking period. But the risk isn’t confined to this one crossing. Up and down Baseline Road, South Phoenix has seen severe, multi-vehicle collisions with fatalities and mass-casualty injuries at intersections along the corridor, reinforcing that the danger runs the length of Baseline Road rather than concentrating at any single crossing.
75th Avenue & Indian School Road (West Phoenix)
Positioned in the heart of Maryvale, the intersection of 75th Avenue and Indian School Road represents one of West Phoenix’s most deadly intersections, logging 249 crashes in Maricopa Association of Governments (MAG) data over a five-year period. Both roads are six-lane arterials with posted speed limits of 40 mph, but they are engineered with the wide lanes, long straightaways, and generous turning bays typical of Phoenix’s major “stroad” corridors, which is a design that tends to encourage speeds above the posted limit.
The consequences at this intersection are routinely severe. In just the past two years, this stretch has seen fatal head-on collisions, a pedestrian struck and killed mid-block, and crashes leaving drivers with critical, life-threatening injuries.
Phoenix Freeway Corridors
Interstate 10 and Interstate 17 form the backbone of the Phoenix freeway system, carrying heavy commuter and freight traffic through downtown and connecting every part of the city. The Loop 101 and Loop 202 circle the metro area, and SR-51 connects north Phoenix to downtown. The newest addition, the 22-mile Loop 202 South Mountain Freeway, cuts through the western foothills of South Mountain Park and has become a fast-growing employment corridor for advanced manufacturing, technology, and semiconductor supply chain companies situated between the Intel campus in Chandler and the Taiwan Semiconductor Manufacturing Company facility in north Phoenix, adding significant new commuter traffic throughout the southern part of the city.
Pedestrian and Bicycle Risk: A Citywide Threat
The danger on Phoenix roadways extends far beyond vehicle-to-vehicle crashes. Phoenix recorded 774 pedestrian crashes resulting in 100 deaths in 2023, giving the city the highest rate of deadly pedestrian collisions among major U.S. cities. That same year, bicycle crashes caused 8 deaths and 257 injuries citywide. This risk to vulnerable road users isn’t confined to the dense, high-speed corridors of Central and West Phoenix, it extends into the city’s most popular recreational cycling areas as well.
South Mountain Park draws heavy cyclist, runner, and hiker traffic along its access roads and the Chandler Boulevard bike path, and that traffic has come at a real cost: multiple cyclists and motorcyclists have been killed on the mountain’s roadways in recent years, including a cyclist struck by a car and another killed by an impaired driver. Lincoln Drive near Camelback Mountain and the trail network around Papago Park see similarly heavy cycling volume, popular road and mountain biking routes that draw riders throughout the Valley. The same underlying risk factors apply, specifically high-speed vehicle traffic sharing the road with cyclists who have little to no protected separation from it.
Crashes on Phoenix freeways and major intersections regularly result in fatal and serious injuries, including traumatic brain injuries, fractures, and debilitating neck and back injuries.
