What is being studied in Tier 1?
Tier 1 consists of a single environmental study to address broad, corridor-wide issues from Pueblo to the vicinity of the Kansas state line. Several corridor location alternatives will be evaluated, including a no-build alternative, and a preferred alternative will be chosen. The goal of Tier 1 is to ensure that the preferred corridor location alternative adequately balances the needs of the communities, resource agencies (i.e., the environment) and transportation system (local, regional and state-wide). At the end of Tier 1, the preferred corridor alternative should be wide enough for CDOT to plan and program future improvements to the facility.
