Three people are dead after a vehicle being driven erratically on Pontoon Road struck another vehicle at the intersection with Wabash Road in Granite City on Saturday, according to First Alert 4 staff. Granite City Police Department officers had seen the erratic vehicle traveling westbound on Pontoon Road at Maryville Road shortly before the crash, and the department has asked the Illinois State Police to take over the investigation.
According to KMOV, the crash killed three people, though the outlet's report does not specify the identities or vehicle assignments of those who died. The Illinois State Police confirmed it is investigating the erratic driving incident and the resulting fatal crash, and the case remains ongoing as of Sunday morning.
A Corridor With a Troubled Recent History
The stretch of Pontoon Road where officers first noticed the erratic driver is no stranger to fatal crashes tied to police observation of dangerous drivers. In June 2025, a 34-year-old motorcyclist died at the very same intersection of Pontoon Road and Maryville Road after speeding away from a Granite City police traffic stop, according to RiverBender.com. Following that crash, Granite City police similarly handed the investigation off to the Illinois State Police Division of Criminal Investigation, mirroring the process now underway.
The corridor's history stretches back further still. In September 2024, a 48-year-old driver was killed nearby when his vehicle left the roadway and struck the West Pontoon Road overpass along Route 203, an incident RiverBender.com reported was investigated jointly by the Granite City Police Department, the Madison County Coroner's Office, and the Metro East Crash Assistance Team. Pontoon Road serves as a major east-west commercial and commuter thoroughfare linking Granite City and Pontoon Beach, and state transportation planning has long targeted the corridor for safety upgrades, including railroad grade separation projects, according to Illinois.gov.
Cameras Went Up Amid a Surge of Violations
The intersection where officers first spotted Saturday's erratic driver, Pontoon Road and Maryville Road, was equipped with automated red-light enforcement cameras by the Granite City Council in January, with formal citations beginning January 20 after a warning period, per RiverBender.com. City officials installed the cameras to address recurring speeding and red-light violations along the commercial corridor.
The enforcement effort quantified just how aggressive driving had become there: Granite City law enforcement issued nearly 1,800 red-light camera citations at the monitored intersection during the first seven months of 2026 alone, according to STL.News. Despite that enforcement volume, Saturday's crash suggests the corridor's underlying risks remain unresolved.
What Happens Next in the Investigation
Once Illinois State Police complete their work, formal reconstruction findings are typically handled by the agency's Traffic Crash Reconstruction Unit, which releases official reports to involved parties or media upon written request for a $20 fee, according to Staver Accident Injury Lawyers. Illinois law also requires that an official crash report be submitted to the state within 10 days for any collision resulting in death, injury, or significant property damage, per the Illinois State Police; those reports are later subject to disclosure under the state's Freedom of Information Act.
Madison County, where Granite City sits, ranks among the top six counties in Illinois for total motor vehicle traffic fatalities, with more than 2,200 traffic deaths recorded since 1975, according to Roadway.report. Statewide, federal data from NHTSA shows that single-vehicle roadway departures and intersection-related collisions account for the vast majority of Illinois traffic fatalities, with roadway departures causing 528 deaths and intersection-related crashes causing 323 deaths out of 1,268 total traffic fatalities in 2022.
A Pattern of Police-Adjacent Crashes in Granite City
Saturday's fatal crash follows other recent incidents in which Granite City police encountered erratic or fleeing drivers. In January, an overnight pursuit that began with Granite City officers crossed state lines into St. Louis before ending in a multi-vehicle crash, a case Hoodline covered in a snowbank crash after a PIT maneuver in north St. Louis. In July, Hoodline also reported on an intentional vehicular collision and subsequent police chase stemming from a neighborhood dispute in Granite City, as well as a major law enforcement investigation following a fatal shooting in nearby Pontoon Beach.
No further details about the identities of those killed Saturday, the vehicles involved beyond the erratic driver's car, or whether officers attempted a stop before the crash have been released. The investigation remains ongoing, and Illinois State Police have not indicated when additional findings might be made public.
