The AARBAA Colorado chapter advocates for separated cycling infrastructure across the state, from mountain passes to urban corridors. We work with CDOT and local municipalities to implement protected bike lanes that account for altitude, weather extremes, and Colorado's unique terrain.

We have 891 active members across 5 chapters statewide, making Colorado one of our most engaged and successful state organizations with major victories in infrastructure policy.

Colorado faces altitude-related visibility issues, steep mountain grades, extreme weather variability, and heavy ski resort traffic on mountain passes like I-70. Our advocacy focuses on grade-separated infrastructure that protects both cyclists and motorists in challenging terrain.

Yes! We've secured 22 major victories including protected lanes throughout Denver's downtown, Boulder Creek Path improvements, and landmark state legislation requiring separated infrastructure on all new CDOT projects. Colorado is now a national model for infrastructure separation.

Absolutely. Colorado's protected bike lanes must handle snow, ice, and de-icing chemicals. AARBAA advocates for priority snow removal on bike infrastructure and designs that prevent ice accumulation while maintaining year-round safety.

Infrastructure Issues We're Addressing

CRITICAL PRIORITY ADVOCATING

I-70 Ski Traffic Creates Dangerous Mountain Pass Conditions

Heavy ski resort traffic on I-70 mountain passes forces cyclists to share narrow shoulders with distracted drivers at high elevation, creating extremely dangerous conditions especially during peak ski season.

Location:

I-70 from Denver to Vail

Affected Areas:

Idaho Springs, Georgetown, Silverthorne, Frisco, Vail

PROPOSED SOLUTION:

Complete grade-separated bike path parallel to I-70 through entire mountain corridor with heated sections for winter use

Last updated: 1/22/2025
HIGH PRIORITY APPROVED

Fort Collins College Avenue Mixing Zone

College Avenue through CSU campus lacks protected infrastructure despite being one of the highest-traffic bike corridors in the state, creating constant conflict between cyclists, motorists, and pedestrians.

Location:

College Avenue, Fort Collins

Affected Areas:

Fort Collins

PROPOSED SOLUTION:

Fully protected bike lanes with physical separation on both sides of College Avenue from Old Town to CSU campus

Last updated: 1/18/2025
HIGH PRIORITY IDENTIFIED

Grand Junction Lacks Protected East-West Corridor

Grand Junction has no protected cycling infrastructure on major east-west routes, forcing cyclists to mix with high-speed traffic on roads designed for vehicles only.

Location:

Broadway and North Avenue, Grand Junction

Affected Areas:

Grand Junction

PROPOSED SOLUTION:

Protected bike lanes on Broadway and North Avenue creating complete east-west protected corridor

Last updated: 12/10/2024
