Illinois Crash Hot Spots: The Most Dangerous Roads and Intersections

Where Illinois Traffic Deaths Happen

In 2025, 1,171 people died on Illinois roads, IDOT says, only five fewer than the year before. Roughly a third of those deaths happened on city streets and another third on state and U.S. routes, while interstates, the roads most people picture first, accounted for about one in seven. Pedestrian deaths ticked up to 219. Work zone deaths more than doubled, from 15 to 36.

Cook County alone accounted for 342 of those deaths. IDOT’s 2022 to 2026 Strategic Highway Safety Plan puts three problems at the top of its list: speeding and aggressive driving, pedestrian deaths, and vehicles running off the road.

An In-Depth Look at High-Risk Corridors

A few Illinois expressways show up in crash coverage again and again. Here’s what makes each one tricky, with figures from IDOT, the City of Chicago or a local safety plan wherever they’ve been published.

1. Stevenson Expressway (I-55): Southwest Suburbs to Downtown

The Stevenson is how much of the southwest suburbs gets downtown, and the commuters share it with a steady stream of freight trucks. Rear-end crashes are the classic Stevenson wreck, usually at rush hour or when traffic stops without warning.

The junction with the Dan Ryan, on the edge of Chinatown, is where one crash can turn into a chain reaction. Rate Field, where the White Sox play, sits beside the Dan Ryan at 35th Street, a short drive south, and game crowds add to the load. In winter, icy bridges and blowing snow make it worse.

2. I-90 Jane Addams Memorial Tollway: O’Hare to Rockford

The Jane Addams Memorial Tollway carries I-90 from the O’Hare area northwest past Schaumburg and Elgin to Rockford, then on toward the Wisconsin line. On any given day you’re sharing it with commuters, semis and out-of-state travelers.

Near O’Hare, drivers cutting across lanes for last-minute exits cause a lot of rear-end and lane-change crashes. West of Schaumburg the road opens up, and in winter that means blowing snow and black ice. In Rockford, the city’s draft safety plan ranks its own streets by serious crashes, and two of them are in the table further down.

3. Eisenhower Expressway (I-290): West Suburbs to the Loop

Also known as the Ike, I-290 brings the west suburbs into the Loop and meets I-90/94 at the Jane Byrne Interchange. It bottlenecks through Oak Park and Forest Park, and that’s where the sideswipes, lane-change crashes and rear-enders pile up.

The lanes are narrow, the ramps come up fast and merging gets aggressive, even outside rush hour. The CTA Blue Line runs in the median through the West Side and alongside the expressway through Oak Park and Forest Park, so stations like Harlem Avenue put pedestrians on the streets around the exits.

4. U.S. Route 45: Mannheim and LaGrange Roads

U.S. 45 heads south through the western suburbs as Mannheim Road and then LaGrange Road, through Orland Park and into Will County at Mokena and Frankfort. Long stretches are lined with strip malls and restaurants, and drivers turning in and out of all those driveways lead to angle crashes and rear-enders.

It’s a hard road to walk, too. IDOT’s 2023 safety assessment for people walking and biking ranked a Mannheim Road segment second among its top five high injury network locations in suburban Cook County, with 36 crashes there from 2005 to 2022.

5. Interstate 57: Chicago to Champaign

I-57 starts at the Dan Ryan on Chicago’s South Side and runs through Kankakee and Champaign all the way to the southern tip of the state, carrying commuters, college students and a lot of freight. Traffic can slow suddenly near gas stations and rest areas. The long gaps between interchanges tempt drivers into speeds that leave them braking too late, and that’s how multi-car crashes start.

Around Champaign it fills with University of Illinois traffic, and winter brings black ice on dark rural stretches. Across Champaign County as a whole, IDOT counted 29 traffic deaths in 2025, up from 10 in 2024.

6. U.S. Route 41: DuSable Lake Shore Drive

Chicago renamed it DuSable Lake Shore Drive in 2021, and it still runs past Grant Park, Soldier Field, the Museum Campus and Navy Pier. Using the city’s Vision Zero data, which leaves out expressways, the Chicago Sun-Times counted 61 deaths on the drive from April 2019 to August 2025. The paper called it the city’s deadliest road.

Sharp curves, thin shoulders and tight merges don’t leave much room at highway speed, and summer tourists and event lane closures add to it. Our Chicago car accident guide covers the city’s other high crash corridors and how to get a Chicago police report.

More High-Crash Locations Across Illinois

The expressways aren’t the whole story. City and county safety plans, IDOT studies and news analyses have put numbers on specific roads and intersections around the state, and these are the ones with published figures.

Some of these roads are getting work. IDOT plans to rebuild the Sangamon and Dirksen intersection in Springfield with dual left turns, medians, new signals and sidewalks, with construction expected to begin in the 2027 to 2028 season.

In Bloomington-Normal, McLean County planners call Veterans Parkway the most dangerous road in the area, and their Reinvent Veterans Parkway study showed options for it in November 2025. And in Will County and just to the west, IDOT is rebuilding I-80 from Ridge Road to U.S. 30, about 16 miles through Joliet and its neighbors, with work expected to finish by the end of 2028.

How to Stay Safe on Illinois’ Most Dangerous Roads

A few habits can help, whether you’re behind the wheel, on foot or on a bike.

For Drivers:

1. Slow down where crashes cluster: IDOT puts speeding and aggressive driving at the top of its safety plan. Keep to the limit on expressways like I-55 and I-290, and ease off more in heavy traffic or bad weather.
2. Signal every time: U.S. 45 and Lake Shore Drive both mean constant lane changes and merges. A signal tells the driver behind you what’s coming.
3. Let aggressive drivers go: Tailgating and weaving are common on stretches like I-90. Leave space and don’t engage.
4. Put the phone away in the city: In the dense parts of Chicago, like Lake Shore Drive or the downtown interchanges, one glance down can be enough. Keep both hands on the wheel.
5. Slow down in work zones: Work zone deaths in Illinois more than doubled in 2025. Merge early and watch for workers and stopped traffic.
6. Be extra alert at night: Some downstate highways and tollways are poorly lit. Use your high beams when you can, and watch for pedestrians and stalled cars.

For Pedestrians:

1. Cross at marked intersections: On wide suburban roads like Cicero Avenue and U.S. 45, crossing mid-block leaves drivers almost no time to react.
2. Make eye contact: Don’t assume a driver has seen you. Wait until the car has fully stopped before you step out.
3. Lose the distractions: Phones and earbuds can keep you from hearing traffic or an emergency vehicle.

For Cyclists:

1. Use bike lanes and trails: Where they exist, use bike lanes and off-street paths like Chicago’s Lakefront Trail. Where they don’t, stay as far right as is safe.
2. Be easy to see: Wear bright colors, run lights at night, and use hand signals so drivers know where you’re headed.
3. Watch intersections closely: Turning drivers often don’t see cyclists. Never assume a driver will yield.

General Tips:

1. Know your route: If your commute includes I-90, I-290 or I-55, build in time for delays and drive defensively.
2. Check the weather before a long drive: Snow, ice and rain raise the risk, especially on I-57 and rural highways.
3. Stay on top of alerts: IDOT’s traveler information or a navigation app will show crashes, closures and construction as they happen.

What to Do If You’re Injured in an Illinois Car Accident

A bad crash on I-55, U.S. 45 or Lake Shore Drive can leave you hurt and unsure what to do first. What you do in the first hours and days matters, for your health, your recovery, and for your finance.

1. Call 911. Even if nobody seems badly hurt, get police to the scene. They’ll write the official crash report, which is what insurers go by. If anyone is seriously injured, ask for an ambulance.
2. Get checked out. Concussions and internal injuries don’t always show up right away. Go to the ER or urgent care, and follow up with your own doctor in the days after.
3. Document the scene if you can. If it’s safe, photograph the vehicles, the damage and the license plates, plus skid marks, signs, weather and road conditions. Get witnesses’ names and phone numbers, and swap insurance information with the other driver without admitting fault.
4. Be careful with adjusters. The other driver’s insurance company may call soon after the crash. You can politely decline a recorded statement until you have your crash report and understand your options.
5. Keep everything. Medical records, bills, repair estimates, missed work, and every letter or email from an insurer.

Which agency has your report depends on where you crashed. The Illinois State Police handle interstates and the Tollway, and city, village or county police handle local roads. Our Illinois crash report guide walks through getting a copy from each.
