Chicago West & Far West Suburbs Personal Injury Lawyers

Interstate 88 — the Reagan Memorial Tollway — is the primary highway spine of the Chicago western suburbs, running from the I-355 interchange near Downers Grove westward through Oak Brook, Downers Grove, Aurora, and toward the I-39 interchange north of Morris. The tollway carries the daily commuter traffic of hundreds of thousands of western suburban residents traveling to Chicago employment, the commercial freight connecting the western suburban logistics facilities to the broader highway network, and the long-distance business travel between Chicago and the Iowa and Quad Cities corridor. I-88's western section through Aurora and toward the Kane County border carries somewhat lower volumes than the eastern tollway sections, but the commercial freight proportion is higher and driver fatigue from long hauls contributes to the crash pattern. The I-88/IL-59 interchange in Aurora and the I-88/US-30 interchange in the vicinity of Aurora's commercial zone are the highest crash-concentration interchange locations on the western tollway.

U.S. Route 20 through Elgin and the western corridor communities — known locally as Lake Street through the suburban sections — is the primary east-west surface arterial of the northern west suburban zone and a consistently high crash-frequency corridor that has evolved from a primary through-route into a commercial strip arterial handling both long-distance travel and intense local commercial access. The section through Elgin carries Elgin's urban traffic alongside through-travel in a corridor that transitions between urban commercial sections with frequent signalized intersections and suburban sections with higher speed limits and longer block spacing — a transition that creates speed management challenges for drivers and produces crash concentrations at the transition points. The US-20 corridor through Hanover Park, Streamwood, and Bartlett handles suburban commuter volumes that consistently exceed the road's capacity during peak hours, producing rear-end and side-swipe crashes characteristic of congested suburban arterial conditions.

Illinois Route 59 running north-south through the western suburban communities — through Bartlett, West Chicago, Warrenville, Naperville, and southward — is the primary north-south arterial of the far western suburbs and one of the highest crash-frequency surface roads in the Chicago suburbs overall. The route passes through or adjacent to some of the western suburbs' highest-density commercial development, including major retail centers, office parks, and mixed-use developments whose access drives generate constant conflict between commercial access traffic and through-traffic on the arterial. The section through Naperville's commercial corridor has been documented as one of the highest crash-rate surface road segments in DuPage County, reflecting the combination of Naperville's enormous traffic volumes, the density of commercial development on IL-59, and the pedestrian exposure in areas where large shopping centers draw pedestrians across a high-speed arterial. North through Bartlett and Streamwood, IL-59 carries comparable commercial development density with similar crash patterns.
