Alternatives Phase Overview

As part of its mission to improve quality of life through transportation, the Utah Department of Transportation (UDOT) has initiated an environmental study along the I‑15 corridor between Farmington and Salt Lake City.

The team has identified the purpose of the study and defined the transportation needs along the I-15 corridor and in the surrounding communities. With the public’s input and based on technical analysis and engineering, the study team has identified potential improvements – known as alternatives – within the corridor. These alternatives are now available for public review and a Public Comment Period is now open and has been extended to January 13, 2023.

Environmental Study Timeline

Environmental Study Process

The study team is following the EIS process established by the National Environmental Policy Act (NEPA). This includes:

  • Learning about issues, needs and potential solutions from the public and other stakeholders.
  • Establishing a purpose and need for any proposed improvements.
  • Developing a broad range of potential transportation solutions.
  • Evaluating environmental impacts of those proposed solutions.
  • Selecting an alternative that best meets the needs.
  • Continuous public and stakeholder engagement.

Quality of Life Framework

As the population in Utah continues to grow at a record pace, transportation planning and development play a key role in keeping Utah moving, facilitating a strong economy, and maintaining a high quality of life. As such this study will use the Quality of Life Framework outlined below to inform decision making including in developing the study Purpose and Need.
