State Highway 71 (CO 71 or SH 71) is a 224-mile-long (360 km) state highway passing several other highways in northern and central Colorado. SH 71's southern terminus is at U.S. Route 350 (US 350) near La Junta, and the northern terminus is a continuation as Nebraska Highway 71 (N-71) at the Nebraska border, which eventually crosses into South Dakota as South Dakota Highway 71 (SD-71), making Highway 71 a triple-state highway.
