According to CDOT's map for Gore Pass, the shoulders are 4 feet or wider. Having just ridden it, it's more like 4 inches. In places it's wider, but for about 95% of it there's little to no shoulder, with 55-65 mph speeds to boot down low and up top. IIRC, the road north out of Kremmling doesn't have a shoulder either. I guess CDOT doesn't know their own roads.
