One person was killed early Sunday, November 8, 2026, when a passenger car and a semi-truck collided on the northbound Dan Ryan Expressway on Chicago's South Side, according to Illinois State Police.

The crash closed all northbound lanes of the expressway for roughly four hours, with traffic diverted off at 43rd Street until around 7 a.m.

Fatal Crash on Dan Ryan Expressway Claims One Life

Illinois State Police said troopers responded to a report of a two-vehicle crash on Interstate 94 northbound at Root Street, near the city's Fuller Park neighborhood. WGN-TV, citing ISP, reported the troopers arrived around 3:15 a.m., while NBC Chicago, also citing state police, reported the initial call came in at approximately 3:11 a.m. Responding troopers pronounced one of the drivers dead at the scene.

Victim Identified as Derricka P. Porter

The Cook County Medical Examiner's Office confirmed that 26-year-old Derricka P. Porter died in the crash. State police accounts relayed by NBC Chicago indicate Porter was one of the drivers involved in the collision. ABC7 Chicago, citing officials, reported that no other injuries occurred, meaning the incident resulted in a single fatality despite involving two vehicles.

Two-Vehicle Collision Involved Car and Semi-Truck

Initial descriptions from state police referred to a two-vehicle or two-car crash without specifying what was involved. ABC7 Chicago later reported that video from the scene indicates the collision involved a semi-truck and a car. The outlet also noted no information was immediately available about the semi's driver or their condition in the initial updates, and authorities did not immediately provide additional details about the circumstances of the collision.

Extensive Traffic Disruptions Followed Incident

The crash had a significant morning traffic impact on one of the city's busiest expressways. All northbound lanes were shut down for the investigation, with traffic diverted off the highway at 43rd Street, state police said. NBC Chicago reported the closure lasted approximately four hours. The lanes reopened just before 7 a.m., meaning the disruption spanned much of the pre-dawn and early-morning commute window on Sunday.

Timeline of Dan Ryan Expressway Crash and Traffic Impact

Sequencing the moments reported by Illinois State Police and the medical examiner's office shows how the incident and its traffic disruption unfolded:

Chronology of the November 8, 2026 Dan Ryan Expressway crash and its traffic impact, per official reports
Time	Event
Approximately 3:11 a.m.	State police receive the report of a two-vehicle crash on the inbound Dan Ryan Expressway
Around 3:15 a.m.	Troopers respond to I-94 northbound at Root Street, near Fuller Park; a 26-year-old woman, later identified as Derricka P. Porter, is pronounced dead at the scene
After troopers arrive	All northbound lanes are shut down for the investigation, with traffic diverted off at 43rd Street
Just before 7 a.m.	All northbound lanes reopen after approximately four hours

The chronology makes the scope of the disruption easy to scan: from the roughly 3:11 a.m. call to the pre-7 a.m. reopening, the northbound Dan Ryan was either the site of a fatal crash investigation or fully closed for about four hours.

Investigation into Crash Cause Ongoing

What caused the crash was not immediately clear, and authorities did not immediately provide additional information, ABC7 Chicago reported. NBC Chicago confirmed an investigation is underway. No details have been released about contributing factors, fault, or any charges, and the cause of the collision remains undetermined in public reporting.

Ongoing Investigation and Commuter Awareness

Commuters should remain aware that major incidents like this one can close core expressway lanes for hours and that official channels are the reliable source for road conditions during such events. The measurable indicator to watch going forward is official statements from Illinois State Police regarding the conclusion of the investigation or any charges filed, which would establish the cause and any accountability for the collision that killed Derricka P. Porter.
