The U.S. Highway 50 (US 50) Tier 1 Environmental Impact Statement (EIS) is a 150-mile broad-scale transportation study from approximately the city of Pueblo, Colorado, to the vicinity of the Colorado-Kansas state line. The corridor traverses four counties and 10 municipalities providing local and regional connections for the distribution of people, goods, and services through and beyond the Lower Arkansas Valley. The purpose for undertaking transportation improvements in the US 50 corridor is to improve safety and mobility for local, regional, and long-distance users of US 50 for present and future travel demand.
