The Montana Department of Transportation (MDT) and Schellinger Construction are making improvements to Interstate 90 (I 90) in Powell and Deer Lodge counties. The project involves reconstructing I 90 beginning just south of the Racetrack Interchange (Exit 195) and continuing south about a half mile. The east and westbound structures over the abandoned railroad bridge south of the Racetrack Interchange will also be removed.
Planned improvements include:
- Removing the abandoned railroad track bridge structures south of the Racetrack Interchange (Exit 195).
- Grading the steep slopes on the side of the interstate.
- Lowering the elevation of the roadway to be closer to the valley floor.
Why is the project needed?
This section of I 90 has a history of crashes. The steep slopes on the sides of the interstate can make these crashes very dangerous. Removing the abandoned railroad track bridges and lowering the elevation of the roadway will enhance safety through this section of interstate.
Will the interstate design change as part of this project?
While the roadway will remain in its current configuration with two lanes in each direction, the interstate will be lowered by about 20 feet to be closer to the valley floor. This change will be possible by grading the steep slopes in the area and removing the abandoned railroad track bridges approximately half a mile south of the Racetrack Interchange (Exit 195).
Stay Informed During Construction
Communication with the public is important to MDT and the success of the project. The community will be notified about construction and traffic activities at key project milestones throughout the construction process. MDT will notify the public through the project website, local media, mailings, social media, and email and text notifications.
Current construction information and road conditions can be found on the MDT Travel Info App.
