A major traffic disruption is impacting commuters in Phoenix, Arizona, as eastbound Interstate 10 is currently closed due to a crash near Jefferson Street. The Arizona Department of Transportation (ADOT) announced the closure, urging drivers to allow extra travel time and anticipate significant delays. This I-10 closure in Phoenix is causing ripple effects across the city’s transportation network, particularly during the afternoon commute.
The incident, first reported by ADOT, occurred at Jefferson Street, a busy interchange on the I-10 Papago Freeway. While the exact details of the crash remain limited, authorities confirmed the complete closure of eastbound lanes as emergency crews work to clear the scene and investigate the incident. The timing of the closure is particularly problematic, coinciding with peak traffic hours for the Phoenix metropolitan area.

Impact on Phoenix Traffic and Alternate Routes
The closure of I-10 eastbound is forcing significant traffic diversions, primarily onto the Loop 202 (Red Mountain Freeway). ADOT is advising drivers to utilize the Loop 202 as an alternate route, but officials warn that this detour is already experiencing increased congestion. The I-10 Broadway Curve area, known for its complex interchange, is particularly susceptible to backups during incidents like this. Motorists traveling east from downtown Phoenix or Tempe are strongly encouraged to seek alternative routes or delay their travel if possible. The Arizona Traveler Information site, az511.gov, and the AZ511 app provide real-time highway conditions and updates on the closure.
According to the Arizona Department of Transportation, I-10 through Arizona spans 391.99 miles [Wikipedia]. Segments of the highway within the Phoenix area are known as the Papago Freeway, Inner Loop, or Maricopa Freeway. Outside of the metro area, it’s designated as the Pearl Harbor Memorial Highway.
Details of the Incident and Emergency Response
While the specific circumstances of the crash have not been fully released, ADOT confirmed that the closure is due to a collision involving at least one vehicle. Emergency responders, including Phoenix Police and Fire Departments, are on scene conducting investigations and providing assistance. The extent of any injuries sustained in the crash remains unconfirmed at this time. Authorities have not provided an estimated time for reopening the eastbound lanes of I-10, emphasizing that the duration will depend on the complexity of the investigation and the speed of debris removal.
The I-10 corridor in Arizona is a vital transportation artery, connecting California to Novel Mexico and serving as a key route for both commercial and passenger traffic. The highway enters Arizona near Ehrenberg and passes through major cities like Phoenix, Tucson, Casa Grande, and Marana before exiting near San Simon [Wikipedia]. Disruptions to traffic flow on this highway can have significant regional economic impacts.

The incident highlights the challenges of maintaining traffic flow on a major interstate highway in a rapidly growing metropolitan area. The Broadway Curve, in particular, is a known bottleneck and a frequent site of traffic incidents. Ongoing infrastructure projects are aimed at improving traffic capacity and safety along the I-10 corridor, but disruptions like this one are inevitable.
As of 2:30 PM MST, ADOT has not released an estimated time for reopening the eastbound lanes of I-10. Crews continue to work diligently to clear the scene and restore normal traffic flow. Motorists are advised to avoid the area if possible and to check the AZ511 resources for the latest updates. The situation remains fluid, and further information will be released as it becomes available.
Authorities will continue to monitor the situation and provide updates as they grow available. The next official update from ADOT is expected around 4:00 PM MST, providing a more detailed assessment of the incident and an estimated timeline for reopening the highway.
