A motorcyclist suffered life-threatening injuries Wednesday morning after a crash with a vehicle shut down US 60/Grand Avenue in both directions near Encanto Boulevard in Phoenix, snarling the morning commute across one of the city's busiest corridors. The Phoenix Fire Department transported the rider to a hospital following the collision, which happened around 7 a.m. near 23rd and Grand avenues.
According to KTAR News, the crash prompted the Arizona Department of Transportation to close the highway at milepost 161 near Encanto Boulevard, with no estimated time given for when the roadway would reopen. ADOT reported the closure and crash details, per the outlet, as crews worked to clear the scene during peak morning traffic. The extent of the vehicle driver's involvement and any potential citations had not been detailed as of the outlet's report.
A Corridor Already Under Construction
The crash lands squarely inside an active work zone. ADOT kicked off an 11-mile pavement rehabilitation project along US 60 from 85th Avenue to Interstate 17 in May, a nine-month effort to replace worn roadway surfaces and upgrade curb ramps that has kept overnight lane restrictions and pavement milling underway along the corridor since late spring, according to the Arizona Department of Transportation.
That work is a precursor to a bigger fix still years out. ADOT and the City of Phoenix signed off on final environmental and design reports in spring 2025 for the $140 million Grand-35 Project, which will raise elevated overpasses at 35th Avenue and Indian School Road above Grand Avenue and the adjacent BNSF rail tracks. Construction on that project isn't slated to begin until summer 2027. Grand Avenue currently carries roughly 50,000 vehicles a day through West Phoenix, a volume that helps explain why even a single crash can lock down the highway for hours.
A Dangerous Stretch With a Recent History
Wednesday's crash happened at the same corridor where a fatal hit-and-run struck a pedestrian at Encanto Boulevard and Grand Avenue in February, a case Hoodline previously covered. Federal crash data analyzed this year found that a two-square-mile stretch of West Phoenix around Indian School Road and Grand Avenue recorded 53 pedestrian and traffic fatalities across 52 separate crashes between 2000 and 2024, marking it as one of Arizona's most dangerous traffic corridors.
Motorcyclists in particular have been hit hard along nearby West Phoenix roads this month. On August 10, a 28-year-old motorcyclist was killed after failing to stop for a red light and colliding with a minivan making a left turn near 35th Avenue and Camelback Road, according to Fox 10 Phoenix; the minivan's driver was uninjured and showed no signs of impairment. That crash came just days after Hoodline reported on another critical motorcycle-vehicle collision at the same West Phoenix intersection.
Statewide Numbers Show Riders at Greater Risk
The dangers facing motorcyclists extend well beyond this one corridor. ADOT's 2024 Motor Vehicle Crash Facts report documented 3,036 motorcycle-involved collisions statewide, resulting in 258 fatalities and 2,571 injuries, with motorcycles accounting for roughly 18% of all Arizona traffic deaths despite making up only about 3% of registered vehicles, according to figures cited by AZ Law Now. National Highway Traffic Safety Administration data cited by traffic safety analysts this year found that motorcyclists face a fatality risk roughly 24 times higher per mile traveled than occupants of passenger vehicles, a gap that high posted speed limits on urban state routes like US 60 can make worse.
Arizona law adds another layer to the equation. Under Arizona Revised Statutes § 28-964, helmet use is mandatory only for motorcycle riders and passengers under 18, meaning adult riders can legally ride without one as long as they wear approved eye protection, per Ramos Law. It is not known whether the rider involved in Wednesday's crash was wearing a helmet.
That legal gap can carry financial consequences long after a crash. Under Arizona's pure comparative fault doctrine, defense insurers in civil litigation can argue that an adult rider's decision to go without a helmet contributed to their injuries, potentially reducing damage payouts even though riding helmetless is legal, according to Feller & Wendt, LLC. Civil juries assign comparative fault percentages partly based on protective gear choices, a factor that has shaped outcomes in past Arizona motorcycle injury cases.
Echoes of a Similar Closure in Glendale
Wednesday's shutdown isn't the first time a motorcycle crash has forced a lengthy closure along this corridor. In November 2023, a 28-year-old motorcyclist was killed in a collision on US 60/Grand Avenue at Orangewood Avenue in nearby Glendale, triggering an overnight dual-direction closure of Grand Avenue between Myrtle and Northern avenues, according to KTAR News. Impairment was ruled out in that earlier crash. As of Wednesday afternoon, no cause had been determined for the Encanto Boulevard crash, and it remained unclear when US 60 would fully reopen to traffic.
