High-Crash Corridors
US-85 / Santa Fe Drive and C-470
US Route 85 (Santa Fe Drive) runs through the heart of Littleton and serves Arapahoe Community College at 5900 S. Santa Fe Drive. State transportation data documented 2,282 crashes on this single corridor over a recent three-year period, attributed to congestion, left-turn conflicts, and freight traffic. Colorado State Highway 470 (C-470, the Centennial Freeway) forms Littleton's southern boundary, carrying heavy traffic past Chatfield State Park, which draws over one million visitors annually. Short on-ramps and off-ramps at the C-470 / I-25 interchange force aggressive merging and produce frequent rear-end collisions. Wadsworth Boulevard (SH-121) and US Route 285 (Hampden Avenue) complete the four major corridors where bus-involved crashes concentrate in the Littleton area.
