Chicago's High Bicycle-Crash Streets: An Interactive Map

• Dooring: on corridors lined with parked cars, opening doors are a leading cause of cyclist injury.
• Complex junctions: six-way and diagonal intersections create multiple conflict paths and blind turns.
• Turning vehicles: right- and left-turning drivers crossing a bike lane are a frequent collision cause at signals.
• Mixed heavy traffic: corridors shared with buses and trucks raise both the frequency and severity of crashes.

• Ride outside the door zone — give parked cars at least three feet of clearance, even inside a bike lane.
• Take the lane through complex intersections where a bike lane disappears or vehicles cross your path.
• Make eye contact with turning drivers and assume you may not be seen.
• Use lights front and rear after dark — Illinois law requires a white front light and a rear reflector or light.

• City of Chicago — Traffic Crashes dataset (Chicago Data Portal) and Vision Zero Chicago materials, which document where bicycle crashes concentrate across the street network.
• Milwaukee Avenue is identified in reported crash data and local reporting as the city's highest bicycle-crash corridor.
• Street and intersection names reflect those documented sources; marker coordinates are approximate locators placed along each named location.
• This map does not assign crash counts or rankings to individual points — it shows documented high-crash locations, not a ranked list.
