Protected Bike Lane Reconfiguration for Chicago's 606 Trail Corridor

## CONTEXT **Situation:** The 606, Chicago's elevated rail-trail park, has transformed the Bloomingdale Trail corridor into a major cycling and pedestrian artery since its 2015 opening. California Avenue, a north-south street intersecting the 606 at its western end, carries significant local traffic and serves as a key connector for cyclists accessing the trail. Currently, the street features painted bike lanes—simple white lines on the pavement—positioned between parked cars and moving traffic. **Complication:** Painted bike lanes on California Avenue are functionally dangerous. Cyclists ride in the "door zone" of parked cars, where a suddenly opened door can cause serious injury or death. The painted lines provide no physical separation from motor vehicles traveling at 25-35 mph. Data from the Chicago Department of Transportation (CDOT) shows that painted bike lanes on streets with parallel parking have a 50% higher crash rate for cyclists compared to protected lanes. The 606's success has increased bike traffic on California Avenue, making this danger more acute. **Question:** Why does Chicago continue to install painted bike lanes in high-traffic corridors where they demonstrably fail to protect cyclists, especially when a proven, low-cost alternative exists? **Answer:** The city can reconfigure California Avenue by swapping the positions of parking and bike lanes, placing the bike lane against the curb with parked cars acting as a physical barrier. This "protected bike lane" design, used successfully in cities like New York, Copenhagen, and Portland, costs roughly the same as painted lanes but reduces cyclist injury risk by 60-80%. The current configuration wastes taxpayer money on infrastructure that does not achieve its stated safety goal. ## PROBLEM **Core Problem:** Painted bike lanes on California Avenue near the 606 create a dangerous illusion of safety. Cyclists are lured into riding in the door zone of parked cars, where a sudden door opening can throw them into traffic. The painted lines do not prevent motorists from parking in the bike lane, drifting into it, or opening doors without checking. This is not a design failure—it is a predictable outcome of a flawed street layout. **Specific Harms:** In Chicago, between 2015 and 2020, there were 1,200 reported crashes involving cyclists on streets with painted bike lanes, with 12 fatalities. On streets with protected bike lanes, the crash rate dropped by 70%. The 606 corridor has seen a 300% increase in bike traffic since 2015, meaning more cyclists are exposed to this risk daily. The cost of inaction includes preventable injuries, emergency room visits, lost workdays, and the emotional toll on families. A single severe cyclist crash can cost the city $100,000+ in emergency services and long-term care. **Cost of Inaction:** If Chicago does not reconfigure California Avenue, it will continue to spend $50,000-$100,000 per mile on painted bike lanes that do not protect cyclists. Meanwhile, peer cities like New York have retrofitted over 1,000 miles of protected bike lanes, reducing cyclist fatalities by 40% citywide. Chicago's inaction sends a message that cyclist safety is not a priority, discouraging bike commuting and undermining the 606's goal of promoting active transportation. ## PROPOSED SOLUTION **Specific Policy:** The Chicago Department of Transportation (CDOT) should immediately reconfigure California Avenue north of the 606 by swapping the positions of parking and bike lanes. The new design would place the bike lane adjacent to the curb, with a buffer zone (e.g., flex posts or concrete curbs) separating it from the parking lane. This is a standard "protected bike lane" design, also known as a "cycle track." **Rejected Alternatives:** - **Do nothing:** Maintains dangerous status quo. - **Remove parking entirely:** Politically unpopular with residents and businesses; reduces street vitality. - **Add physical barriers to existing layout:** More expensive and complex than a simple swap. - **Close the street to cars:** Disruptive and unnecessary for this corridor. **Implementation Machinery:** CDOT can implement this reconfiguration through a "quick-build" process using temporary materials (flex posts, paint, signage) within 6-8 weeks, at a cost of $30,000-$50,000 per mile. This mirrors the approach used in New York City's "Green Wave" program and Portland's "Neighborhood Greenways." The city would need to: 1. Conduct a 30-day public comment period (already done for similar projects). 2. Install temporary barriers and repaint lane markings. 3. Monitor for 6-12 months, then make permanent with concrete curbs if successful. 4. Coordinate with the Chicago Transit Authority (CTA) to ensure bus stops remain accessible. **Process:** CDOT should prioritize this corridor because of its connection to the 606, a major city investment. The reconfiguration aligns with Chicago's "Complete Streets" policy and the "Chicago Bike Plan 2020-2025," which calls for 100 miles of protected bike lanes by 2025. ## EXPECTED IMPACT **Who Benefits:** - **Cyclists:** 60-80% reduction in injury risk. Daily users of the 606 corridor (estimated 5,000 cyclists per day in summer) will have a safer connection to the trail. - **Pedestrians:** Protected bike lanes reduce sidewalk riding, improving pedestrian safety. - **Motorists:** Clearer lane markings reduce confusion and erratic driving. - **Local businesses:** Protected bike lanes increase foot traffic and retail sales by 10-20% (per New York City Department of Transportation data). - **City budget:** Reduced emergency response costs and liability claims. **Metric Changes:** - Cyclist crashes on California Avenue: Projected 70% reduction within 12 months. - Bike ridership: 20-40% increase within 2 years, as safer infrastructure attracts new riders. - Parking utilization: No change, as parking spaces are preserved. - Traffic speed: Slight reduction (1-2 mph) due to narrower travel lanes, improving safety. **Scope and Magnitude:** This is a small-scale project (approximately 1 mile of California Avenue) but with high visibility due to the 606 connection. Success here would create a template for retrofitting other painted bike lanes citywide. Chicago has 200+ miles of painted bike lanes on streets with parallel parking—a $10-20 million retrofit opportunity that could prevent 50+ serious crashes annually. ## DECISION LENS | | If this passes | If this doesn't pass | | --- | --- | --- | | What will happen | Protected bike lane installed; cyclist injuries drop 60-80%; bike ridership increases 20-40%; parking preserved; template for citywide retrofit created. | Painted bike lanes remain; cyclist injuries continue at current rate; public frustration grows; city misses Complete Streets target; liability risk persists. | | What won't happen | No significant parking loss; no major traffic disruption; no increase in emergency costs; no loss of business access. | No safety improvement; no ridership increase; no cost savings; no progress toward bike plan goals; no demonstration project for other corridors. | ## PRECEDENTS EXAMPLE: New York City — What: NYC converted 1,000+ miles of painted bike lanes to protected lanes using flex posts and concrete curbs, including on major avenues like 8th and 9th Avenues. — Outcome: 40% reduction in cyclist fatalities citywide; 50% increase in bike ridership on protected lanes; 10-20% increase in retail sales on corridors with protected lanes. — Outcome: 40% reduction in cyclist fatalities citywide; 50% increase in bike ridership on protected lanes; 10-20% increase in retail sales on corridors with protected lanes.
