Denver police are investigating a serious crash near 56th Avenue and Argonne Street that left two motorists with serious injuries Saturday, prompting officers to urge drivers to steer clear of the area. The department warned of delays and recommended alternate routes while the investigation continues.
The Denver Police Department shared the alert on X at 5:21 p.m. on October 24, 2026, writing that officers were “investigating a traffic crash near 56th Ave and Argonne St involving two motorist resulting in serious injuries,” according to the Denver Police Dept.
The department added, “Expect delays in the area. Alternate routes advised.”
No further details on the crash — including its exact timing relative to the post, whether any roads were closed, or the specific nature of the injuries — have been released. It's also unclear whether citations or arrests resulted from the incident, as that information has not been made public.
Why Police Only Flag Certain Crashes
Not every fender-bender in Denver generates a public alert. The department's own crash-alert disclaimer explains the threshold officers use before pushing out a notice: “We will only issue a Crash Alert if at least one involved person sustains serious injuries or the crash results in road closures,” according to the Denver Police Department crash-alert disclaimer. That standard means the Argonne Street crash cleared a meaningful bar for severity even though the full scope of injuries hasn't been detailed.
A separate, lower-confidence post attributed to Denver police described a different crash, at 56th and Peoria, involving a single motorist who suffered serious injury. It's not established whether that post refers to the same incident as the Argonne Street crash or a separate one entirely, and Hoodline is noting both versions rather than assuming either is the full picture.
A Stretch of Road With a History
The 56th Avenue corridor near Peoria Street has seen serious crashes before. Back on May 14, 2015, Denver police shut down 56th Avenue in both directions at Peoria Street after a fatal two-vehicle wreck involving a semi-trailer, according to The Denver Post. That crash was reported at about 8 a.m., and initial reports indicated one person was seriously injured before police announced just after 9 a.m. that the crash had turned fatal, the newspaper reported. That earlier incident offers context for the corridor's history but doesn't establish any details about Saturday's crash.
Residents looking for broader context on crash patterns across the city can consult Denver's Vision Zero dashboard, which is described as tracking fatal and serious-injury crashes dating back to 2013 and updating daily on weekdays, per the City and County of Denver.
Denver police have not released additional updates on the Argonne Street crash, including whether any roads remain affected or whether investigators have determined a cause. Drivers in the area are advised to continue watching for alternate route guidance until the department provides further information.
