Project Overview

The Montana Department of Transportation (MDT), in partnership with engineering firm Sanbell, has begun the design phase of an improvement project to enhance safety features and accessibility at the intersection of Mill Street and Rabel Lane with U.S. Highway 191 (US 191)/Gallatin Road in Gallatin Gateway.

A new traffic signal will be installed to help address intersection-related crashes and operational concerns. Other improvements include adding sidewalks and sidewalk ramps that meet current Americans with Disabilities Act (ADA) standards.

Planned improvements include:

  • Installing a new traffic signal at the intersection of Mill Street and Rabel Lane with US 191/Gallatin Road.
  • Installing LED lighting at the intersection.
  • Widening Mill Street on the west side of the intersection to include a left turn lane.
  • Installing a new sidewalk with ADA-compliant ramps to provide connectivity from the existing trail along Mill Street to Gallatin Gateway School.
The project area is highlighted in orange along Mill Street, running east–west through its intersection with US Highway 191 (also labeled Gallatin Road). US 191 runs north–south. Nearby streets include Bozeman Street, Webb Street, Bench Street, Rabel Lane, Davenport Street, Hargrove Loop, and Latigo Drive. Landmarks shown include Gallatin Gateway School, Gallatin Gateway Community Center, Big Timberworks Inc., and the United States Postal Service. A legend identifies the orange segment as the project area, and a compass rose indicates north.

Tentative Timeline

The project is currently in the early design phase. As part of this phase, a project open house will be scheduled for the community to learn more, share their feedback, and ask questions directly to the project team.

A date for this open house has not yet been set. In the meantime, the public is encouraged to reach out with thoughts and questions by calling the project hotline at 406-207-4484, operating Monday through Friday from 9 a.m. to 5 p.m., or by emailing sloaneXYZbigskypublicrelationsABCcom.

Email updates will be provided at project milestones. To subscribe to updates, please email Sloane Stinson.

A construction date for the project has not yet been scheduled.

Project Funding

The Mill Street Intersection Improvements project is being funded through the Highway Safety Improvement Program (HSIP). The primary focus of the program is to identify locations where higher-severity crashes have occurred and prioritize work to reduce them.
