State Highway 71 (CO 71 orSH 71) is a 224-mile-long (360 km) state highway passing several other highways in northern and centralColorado. SH 71's southern terminus is atU.S. Route 350 (US 350) nearLa Junta, and the northern terminus is a continuation asNebraska Highway 71 (N-71) at theNebraska border, which eventually crosses into South Dakota asSouth Dakota Highway 71 (SD-71), making Highway 71 a triple-state highway.
State Highway 71 is the subject of a truck freight diversion feasibility study being conducted by theColorado Department of Transportation to explore diverting truck traffic fromInterstate 25.[2]
