Most Dangerous Roads and Intersections in the Chicago Suburbs

The Eisenhower Expressway averages approximately 2,000 crashes per year on the 8-mile stretch between Manheim Road and Cicero Avenue, passing through Maywood, Forest Park, Oak Park, and into Chicago's Austin neighborhood (IDOT). That's more than five crashes every single day on one short stretch of highway.

The design of I-290 drives the crash numbers. Left-side exit ramps at Harlem Avenue and Austin Boulevard force drivers to merge across high-speed traffic, creating sudden speed differentials and lane-change conflicts. Speeding contributes to 33-34% of all crashes and over 36% of fatal crashes on this corridor. The expressway was built in the 1950s for lower traffic volumes, and decades of suburban growth have pushed daily vehicle counts far beyond its design capacity.

Rear-end collisions during congestion and high-speed sideswipe crashes during lane changes are the dominant crash types. If you commute on I-290, the highest-risk segments are the interchange with I-88 in Hillside and the merge zones near Harlem Avenue. Keep extra following distance and avoid last-second lane changes near the left-side exits.

Route 59 accounts for 15.9% of all crashes in Naperville — more than any other single road in the city (Naperville Police Department). The Route 59 and North Aurora Road intersection recorded over 110 crashes from 2016 to 2024, making it one of the most dangerous intersections in DuPage County. The Route 59 and 111th Street intersection sees over 55 incidents in a typical year.

Route 59 runs north-south through the heart of Naperville's commercial corridor, connecting I-88 to the south suburbs. The road carries heavy volumes of commuter traffic, turning movements into shopping centers and office parks, and frequent red-light running at congested intersections. Speed limits transition between 35 and 45 mph through areas with dense commercial driveways, creating conflicts between through traffic and vehicles slowing to turn.

In Joliet, the pattern repeats: the Caton Farm Road and Route 59 intersection recorded 37 crashes and 10 injuries in 2021. Route 59 and Theodore Street saw 35 crashes and 9 injuries the same year. The entire Route 59 corridor from Joliet through Naperville to Bartlett demands constant alertness from drivers.

Ogden Avenue is listed by IDOT as one of the top roads for rear-end crashes in DuPage County. The road runs diagonally through the county's commercial core, and the intersection at Ogden Avenue and Washington Street in Naperville recorded 102 reportable crashes from 2016 to 2024 (IDOT / Naperville PD). In Aurora, the Ogden Avenue and Montgomery Road intersection saw 103 reportable crashes in the same period.

The crash pattern on Ogden Avenue is driven by its dual identity: a state highway carrying through traffic at 40-45 mph through areas dense with strip malls, restaurants, and big-box retailers. Drivers attempting to turn into commercial driveways slow suddenly in the travel lane, and following vehicles — often traveling at speed — don't react in time. The result is a near-continuous chain of rear-end collisions.

Ogden Avenue's crash rate peaks during evening rush hour and weekend shopping periods when the mix of commuters and local traffic is highest. If you drive this corridor regularly, maintain extra following distance through the commercial stretches between Naperville and Downers Grove.

An IDOT crash analysis found 670 total crashes on a 6-mile stretch of Butterfield Road in DuPage County, with 88% classified as rear-end or turning collisions. Eight key intersections along this stretch accounted for 387 of those crashes and 83 injuries. The Butterfield Road and Kirk Road intersection alone recorded 84 serious crashes from 2016 to 2024.

Butterfield Road connects Wheaton to Warrenville through a corridor of office parks, corporate campuses, and retail centers. The combination of high-speed through traffic and heavy turning volumes at commercial entrances creates the same rear-end collision pattern seen on Ogden Avenue. Signal timing that prioritizes through traffic means turning vehicles often wait in the travel lane, exposed to following traffic.

In Aurora, the Butterfield Road and Eola Road intersection recorded 58 crashes, while Butterfield and Farnsworth Avenue saw 35 crashes in a recent year. The entire corridor from I-355 west to Route 59 should be treated as a high-risk zone for rear-end crashes.

75th Street runs east-west through Naperville, Woodridge, and Darien, connecting several major north-south routes. The 75th Street and Naper Boulevard intersection recorded 97 reportable crashes from 2016 to 2024, and 75th Street and Washington Street saw 94 in the same period (IDOT / Naperville PD).

The road passes through dense commercial and residential areas with heavy turning movements. Speed limits of 40-45 mph through these zones give drivers little time to react to vehicles entering the road from shopping centers and side streets. The mix of SUVs, commercial vehicles, and school traffic during morning and afternoon hours adds complexity.

75th Street crashes peak during the afternoon rush and are dominated by angle collisions at intersections — vehicles turning left across oncoming traffic or running red lights. If you're making a left turn at any 75th Street intersection, take extra time to verify the intersection is clear before proceeding.

I-88 (Reagan Memorial Tollway) is a major east-west corridor through DuPage County connecting the western suburbs to Chicago. IDOT reports it has one of the highest accident rates in the region, with hundreds of crashes annually. The I-88 and Naperville Road interchange recorded 90 serious crashes from 2016 to 2024, making it one of the deadliest interchange locations in the collar counties.

I-355 (Veterans Memorial Tollway) runs north-south through DuPage and Will Counties, connecting I-55 to I-88 to IL-64. Merge zones where I-355 meets I-88 and I-55 are consistent crash hotspots due to high-speed weaving between closely spaced ramps. The CMAP (Chicago Metropolitan Agency for Planning) congestion management system tracks crash rates per 100 million vehicle miles traveled along the corridor, and several segments exceed the regional average.

Speeding is the common thread. Nearly half of fatal crashes statewide involve speeding (IDOT 2023 Crash Facts), and the tollways — with their higher speed limits and long straight stretches — amplify the problem. The most dangerous time on both corridors is Friday afternoon through Sunday evening, when recreational and weekend traffic mixes with commercial trucks.

In Aurora — Illinois' second-largest city — two corridors stand out for crash frequency. Farnsworth Avenue and Molitor Road recorded 108 reportable crashes from 2016 to 2024. Route 31 and Indian Trail topped all Aurora intersections with 115 reportable crashes in the same period (IDOT / Aurora PD).

Aurora's rapid suburban growth has created traffic volumes that exceed what many of these roads were designed to carry. Farnsworth Avenue runs through a corridor of retail and residential development where turning vehicles conflict with 45 mph through traffic. Route 31 carries both local and regional traffic through mixed-use areas with limited turn lanes and pedestrian infrastructure.

Kane County as a whole recorded 48 traffic deaths in 2023, up from 43 in 2022 — an 11.6% increase that runs counter to the statewide trend of declining fatalities. Three cyclist deaths in 2023 were linked to turning vehicle collisions on major collector roads like these.

The six-county Chicago metro region recorded 144 pedestrian fatalities in 2024, up from 135 in 2023 — a 6.7% increase (IDOT). Statewide, 219 pedestrians were killed in 2024, up 9.5% from the year before. The suburban pedestrian death toll is rising even as overall traffic fatalities decline.

The problem is road design. Suburban arterials were built for cars, not people. Wide, high-speed roads with infrequent crosswalks and minimal sidewalks force pedestrians to cross multiple lanes of fast-moving traffic. Research shows that vehicles with hood heights exceeding 40 inches — which includes most modern SUVs and trucks — are 45% more likely to cause pedestrian fatalities than smaller vehicles.

DuPage, Will, and Kane Counties have significant pedestrian exposure along routes like Ogden Avenue, Route 59, and 75th Street, where bus stops, retail entrances, and residential developments line roads with 40-45 mph speed limits and no protected crossings. If you're walking along any suburban arterial, cross only at signalized intersections and make eye contact with drivers before stepping into the road.

After any crash in the Chicago suburbs: move to safety if possible, call 911, and request a police report. Illinois law requires drivers to report crashes that involve injury, death, or property damage exceeding $1,500. Exchange information with the other driver and photograph the scene, vehicle damage, road conditions, and any visible injuries.

Seek medical attention even if you feel fine. Rear-end collisions on high-speed roads like I-290, I-88, and Butterfield Road frequently cause whiplash, concussions, and soft tissue injuries that don't present symptoms for hours or days. Your medical records from the days immediately following the crash are critical evidence for your claim.

Illinois follows a modified comparative negligence rule (735 ILCS 5/2-1116) — you can recover damages only if your share of fault is 50% or less. Your damages are reduced by your percentage of fault. The statute of limitations for personal injury claims is 2 years from the date of injury (735 ILCS 5/13-202). For wrongful death, the deadline is also 2 years from the date of death. Don't wait to understand your options.
