High-Crash Corridors for Cyclists
Wadsworth Boulevard, US-85, and C-470
Wadsworth Boulevard (SH-121) runs north-south through Littleton and carries heavy commuter traffic past the Chatfield State Park entrance, a destination that draws more than one million visitors annually and spikes weekend bicycle traffic at the Wadsworth approach. US Route 85 (Santa Fe Drive) is one of the most crash-concentrated roads in the state: state transportation data documented 2,282 crashes on this single corridor in a recent three-year period, driven by congestion, left-turn conflicts at signalized driveways, and freight traffic. C-470 forms Littleton's southern boundary and features short on-ramps and off-ramps where merging vehicles routinely cut across bike lane approaches. US-285 (Hampden Avenue) completes the four major corridors where bicycle-vehicle conflicts concentrate across the Littleton area.
