Wolf Creek Pass, once a two-lane road winding through the San Juan Mountains between South Fork, Colorado, and Pagosa Springs, has been expanded into a multi-lane highway, greatly increasing the traffic capacity of the pass and making it more navigable in bad weather. It is the easiest access to southwest Colorado from the rest of the state, as all remaining overland routes require lengthy detours through New Mexico or over Lizard Head Pass, near Telluride, or the intimidating Red Mountain Pass, a two-lane road winding along sheer cliffs from Ouray to Silverton.
