Project Overview

The Billings Bypass project is a multi-phase project that will result in a new arterial roadway. The new road will begin at the Johnson Lane Interchange in Lockwood, Montana, span the Yellowstone River, and connect to the Highway 312/Highway 87 intersection in the Billings Heights. An additional segment has reconstructed Five Mile Road north of the new road and will connect Five Mile Road to Old Highway 312.

This project is led by the Montana Department of Transportation in cooperation with the Federal Highway Administration (FHWA), Yellowstone County, and City of Billings. DOWL is the lead project engineer and public information coordinator and Morrison-Maierle is the lead bridge engineer. Kittelson and Associates along with Marvin and Associates are performing the traffic engineering and operational analyses.

Current Status:

  • • The Five Mile Road project segment is complete.
  • • The Yellowstone River Bridge segment is currently under construction.
  • • The Railroad Overpass segment was moved up in the project schedule. It is now scheduled for construction in 2022. This adjustment will allow for public use of the new river crossing after the completion of the Railroad Overpass using a temporary connection to Coulson Road.
  • • The Johnson Lane Interchange segment design is approximately 60% complete. Meetings with property owners and stakeholders are ongoing; please reach out to the project team at or 406-294-9668 if you have any questions or comments. Construction on this segment of the project has been moved to 2023 to allow for additional property owner coordination. Again, this schedule change is not anticipated to impact the overall project delivery schedule.

Additional detail about each project segment is available on the Status / Schedule page.
