What is the I-90 East Belgrade Interchange Environmental Assessment?

Gallatin County, the City of Belgrade, and the Gallatin Airport Authority have initiated the process to obtain approval for a new interchange access on I-90 in East Belgrade. 

The focus of the effort will be an environmental review, which will follow an evaluation and public involvement process to meet the requirements of the National Environmental Policy Act (NEPA) and the Montana Environmental Policy Act (MEPA). This process will ensure that there is a full and fair discussion of all significant social, economic, and environmental impacts before specific project-related decisions are made. The decision-making process will be documented in an Environmental Assessment that will be available for public review and comment.

What is the project’s primary purpose?

The primary purpose of the project is to provide an intermodal link between the interstate facility and the Gallatin Field Airport.  Additional benefits will include reduced congestion and improved regional and local mobility. In addition to the proposed interchange facility, the project could also include the construction of a connector road to the Frontage Road (U-605 / S-205) intersecting at the existing entrance to the Gallatin Field Regional Airport (U-610) to the north, and a connector road linking the existing Alaska Road to the south.

Where will the project be located?

Previous efforts conducted by Gallatin County have identified the general location of the proposed interchange.  An Alternatives Analysis will be conducted to identify a Preferred Alternative that is physically feasible, environmentally sound, and compatible with local planning.
