High-Crash Corridors
High-crash corridors: US 550 and US 160
Durango sits at the confluence of two of the most documented high-crash corridors in southwest Colorado, and distraction is especially dangerous on both. US 550 runs through Durango as Camino del Rio and Main Avenue before climbing north as the Million Dollar Highway through Coal Bank Pass, Molas Pass, and Red Mountain Pass toward Silverton and Ouray, with no guardrails on large sections, lanes as narrow as 23 feet, and tight mountain curves with steep drop-offs; CDOT documented 53 crashes over a 15-mile stretch south of Ouray from 2020 to 2024, with 33 of those involving vehicles leaving the roadway. US 160 carries east-west traffic through Durango toward Wolf Creek Pass and Pagosa Springs to the east and Farmington, New Mexico to the west, a corridor CDOT has documented for scheduled winter closures due to heavy snowfall and avalanche risk. Main Avenue through downtown, which carries US 550 traffic as a through-route, has its own documented history of fatal and serious pedestrian crashes on its north segment. A driver who can manage inattention on a flat city street cannot on a narrow mountain grade.
