EIS Process

We are preparing an Environmental Impact Statement (EIS) to study a potential transportation corridor in western Davis and Weber counties. The National Environmental Policy Act (NEPA) outlines how we must conduct the EIS process. For more detailed information click here to visit the Federal Highway Administration's website.

The environmental process began in 2010. Large and complex EIS’s can take three to seven years to complete. This amount of time is necessary to complete the steps required by NEPA, and to be as thorough as possible to ensure that the best solution is selected. We continue to work closely with the public and other study partners to ensure all options are considered to identify a transportation solution that is a benefit to Davis and Weber counties.


We gather initial data and input from all interested groups regarding issues that should be addressed during the study.

Your input together with current and projected traffic data help define the transportation needs in the study area.

We consider all transportation options and study in detail alternatives that effectively resolve the identified needs. You have the opportunity to review, discuss and provide feedback on the proposed alternatives at open houses and throughout the study.

We examine potential human, community, cultural, economic and environmental concerns for each alternative and compile the analysis in a comprehensive report called the Draft Environmental Impact Statement (EIS).

You have the opportunity to learn, review, discuss and provide feedback on the Draft EIS at open houses or any time during the comment period, which lasts for at least 45 days.

We respond to all comments received about the Draft EIS and publish a Final EIS. A preferred solution will be presented in the Final EIS.

The Federal Highway Administration (FHWA) reviews the Final EIS and issues a Record of Decision identifying the selected alternative based on all data and comments presented in the Final EIS.
