High-Risk Roads
I-70, C-470, Wadsworth, and West Colfax
Lakewood is the gateway to the I-70 Mountain Corridor, the most freight-traveled mountain highway in Colorado, with documented high crash frequency on steep grades, shaded ice patches, and unpredictable weather between Denver foothills and passes including Floyd Hill, the Eisenhower Tunnel, and Vail Pass. C-470 (SH 470) forms the southwestern Denver beltway, where the Wadsworth Boulevard interchange generates heavy stop-and-go rear-end crashes. West Colfax Avenue (Business Loop I-70 / US 40) is a documented pedestrian and bicycle danger corridor between Wadsworth and Sheridan, with intersections at Kipling Street, Lamar Street, and Wadsworth among the most dangerous in the city. US Highway 6 (6th Avenue) and Wadsworth Boulevard (CO 121) are primary commercial delivery corridors with large truck volume at Colorado Mills and the surrounding industrial zones.
