Colorado State Highway 3

Colorado State Highway 3 (SH-3) is a short north–south state highway in La Plata County, Colorado, United States (almost entirely within the southern part of the city of Durango). It follows the former alignment of U.S. Route 160 (US 160) and U.S. Route 550 (US 550) south of downtown, lying across the Animas River from the modern highway constructed about 1980.
