I-70 Revised Draft PEIS

The Colorado Department of Transportation (CDOT) and the Federal Highway Administration (FHWA) have been analyzing the Interstate 70 (I-70) Mountain Corridor for more than 10 years. The agencies released a Draft PEIS in 2004 and the public identified more than 2,000 concerns during an extended public comment period. In 2007, CDOT and FHWA began working with the Collaborative Effort to develop a long-term solution to congestion along the I-70 Mountain Corridor. The Collaborative Effort reached a multi-modal Consensus Recommendation in July 2008.

The agencies announced in Feb. 2010 they would prepare a Revised Draft PEIS for the I-70 Mountain Corridor to expedite the completion of the Final PEIS.

The Revised Draft Programmatic Environmental Impact Statement (DPEIS) for the I-70 Mountain Corridor provides a comparative analysis of alternatives, examining the project’s ability to meet purpose and need while providing the best opportunity to minimize impacts on the surrounding communities. The document examines each natural and social resource to determine potential impacts to the resources from the proposed improvements.

With this Revised DPEIS, CDOT and FHWA provide a complete document that guides agency actions, communicates Tier 1 decisions, and benefits the Corridor and its stakeholders. The Revised DPEIS explains how proposed projects will be implemented at Tier 2, which allows for more focused discussions and site-specific analysis.
