Overview

The Montana Department of Transportation (MDT) is developing a corridor study of Interstate 90 (I-90) between the West Three Forks Interchange in Broadwater County and Bear Canyon Road Interchange in Gallatin County. The purpose of the I-90 Corridor Study is to develop a comprehensive long-range plan for managing the corridor and determine what improvements can be made to address identified needs while considering public and agency input, environmental constraints, access management, and financial feasibility.

The study will be a collaborative process with MDT, the Federal Highway Administration (FHWA), local jurisdictions, resource agencies, and the public to identify transportation needs and potential solutions.
