About the Project

Project History

As the primary route between Northern Colorado and the Denver metropolitan area, the I-25 corridor has experienced considerable growth over the years. People are increasingly aware that demands on the existing transportation system are exceeding its ability to serve travelers efficiently. Along with increased traffic volume on I-25 and parallel roadways has come an increase in accidents, resulting in a need to plan for transportation improvements within the corridor.

In 1993, CDOT initiated an “Environmental Assessment” (EA) for improvements to enhance the capacity and safety of I-25 between SH 7 and SH 66. The EA was followed by a "Finding of No Significant Impact" in 1995 that enabled CDOT to proceed with a series of construction projects that are ongoing. The current construction activities between SH 7 and Weld County Road 16 were addressed in the EA. Also addressed were the right-of-way acquisitions and utility relocations currently underway between Weld County Road 16 and SH 66. These are being done in anticipation of future construction.

In the late 1990s, CDOT, in conjunction with regional planning groups (North Transportation and Air Quality Planning Council, Upper Front Range Regional Planning Commission, and Denver Regional Council of Governments), undertook the North Front Range Transportation Alternatives Feasibility Study (TAFS) to evaluate an extensive range of alternative highway improvements, bus-transit alternatives, passenger-rail alternatives, and travel demand management programs from SH 7 to SH 14. This study, published in March 2000, produced a Vision Plan that included inter-regional bus service, combination general purpose/high-occupancy vehicle lanes, and passenger-rail service.

More recently, a number of studies have been conducted to establish planning guidelines for growth in segments of this corridor, addressing both land use and transportation issues.

The initiation of the North I-25 EIS represents the next step in evaluating and planning for improvements in this corridor.

Purpose and Need

The Federal Highway Administration (FHWA) and the Federal Transit Administration (FTA), in cooperation with the Colorado Department of Transportation (CDOT), have initiated preparation of an Environmental Impact Statement (EIS) to identify and evaluate multi-modal transportation improvements along approximately 70 miles of the I-25 corridor from the Fort Collins-Wellington area to Denver. The EIS will address regional and inter-regional movement of people, goods and services in the I-25 corridor. Read the complete Purpose and Need PDF (1MB)
