The High Plains Highway is a 222-mile corridor that begins near Kit Carson and ends at I-80 in Nebraska. It was identified as a corridor connector in the Eastern Colorado Mobility Study. The High Plains Highway Corridor Coalition (HPHC) -a formal association of towns and counties along the corridor - asked the Colorado Department of Transportation (CDOT) to assist the member communities in developing a plan for the corridor to anticipate and prioritize future corridor transportation needs.
