One Dead After Pre-Dawn I-55 Crash Near Bridgeport Snarls Chicago Traffic

A driver was pronounced dead at the scene and another person was hospitalized after a two-vehicle crash shut down all southbound lanes of the Stevenson Expressway near Wentworth Avenue on Chicago's Near South Side early Saturday morning. Illinois State Police responded to the crash at approximately 4:30 a.m. near the Bridgeport neighborhood, where the roadway remained closed for an investigation.

According to ABC7 Chicago, one person was pronounced dead at the scene while another was transported to a local hospital following the two-vehicle collision on southbound Interstate 55. The cause of the crash was not immediately clear, and authorities had not released further information as of the station's report. As reported by FOX 32 Chicago, state police diverted all southbound I-55 traffic onto southbound Interstate 94, the Dan Ryan Expressway, funneling drivers through one of the region's busiest interchanges.

The Wentworth Avenue stretch of I-55 sits just beside the interchange connecting the Stevenson and Dan Ryan expressways, a corridor where lane closures tend to ripple quickly across the wider transit network, per the same account from Fox 32. With southbound I-55 fully closed for the investigation, drivers heading toward the southwest suburbs were left navigating an unplanned detour during what would otherwise be a quieter overnight stretch of road.

A Corridor With a History of Fatal Overnight Crashes

Saturday's crash adds to a string of fatal incidents along the same expressway system over the past year and a half. Hoodline previously reported that a motorcyclist was struck and killed on the outbound Stevenson Expressway near Damen Avenue in March 2025, a site less than two miles west of Saturday's crash scene. Another Hoodline report detailed a fatal multi-vehicle crash near the Cass Avenue exit in May 2025 that closed southbound I-55 lanes for six hours, and a separate early-morning triple-vehicle crash near Lemont Road in DuPage County that June killed two people and shut down northbound lanes for hours. Just last month, a pre-dawn crash on the Dan Ryan Expressway near 26th Street left one person dead and diverted traffic onto I-55, underscoring how closely intertwined the two expressways' safety problems have become.

Why Pre-Dawn Highway Crashes Turn Deadly

Statewide data helps explain why early morning crashes like Saturday's carry outsized risk despite lighter traffic volumes. Illinois Department of Transportation figures cited by John J. Malm & Associates show Cook County accounted for more than half of all traffic collisions statewide in 2023, recording 160,036 crashes that resulted in 356 fatalities and nearly 30,000 injuries. Separately, IDOT data reported by Salvi, Schostok & Pritchard P.C. found that excess speed was a contributing factor in 45% of all fatal collisions across Illinois in 2024, out of 303,913 total crashes recorded that year.

The Stevenson Expressway itself is no stranger to congestion and friction points. The Chicago Metropolitan Agency for Planning has identified the Stevenson as one of the most congested segments in the regional highway system, prompting IDOT proposals to add managed lanes between I-355 and the Dan Ryan Expressway to reduce weaving hazards. A 2024 global traffic study reported by the Bryant Law Group ranked the Stevenson and Dan Ryan among the most congested corridors in the country, with peak-period commuters on the Stevenson losing roughly 64 hours a year to delays.

Investigation Could Take Weeks to Conclude

No details about the vehicles, drivers, or a possible cause have been released, and it remains unclear whether speed or any other factor played a role in Saturday's crash. Illinois State Police typically rely on specialized Traffic Crash Reconstruction Unit specialists for fatal highway incidents, and forensic reconstruction reports for such cases average 50 to 80 days to complete, according to a report by KSDK. Under state police regulations, drivers involved in a crash causing injury, death, or significant property damage are required to file an official report within 10 days if law enforcement does not complete one on scene.

For now, the Bridgeport-area crash scene remains an active investigation, and neither the identity of the person killed nor the condition of the hospitalized victim has been made public. Drivers on Chicago's Near South Side should expect continued disruptions to the Stevenson-Dan Ryan interchange as investigators complete their work at the scene.
