Project Overview
The Montana Department of Transportation (MDT) is rehabilitating approximately 6 miles of Interstate 90 (I-90) between Bozeman and Livingston. The project begins at the Fort Ellis Road overpass and proceeds east through the canyon to the Jackson Creek Road Interchange (Exit 319). The project will see both the east and westbound lanes of I-90 resurfaced along with several other improvements.
Construction is anticipated to begin in August 2025 and be completed in the 2026 construction season.

Planned Improvements
The planned improvements will rehabilitate I-90 between the Fort Ellis Road overpass to the Jackson Creek Road Interchange (Exit 319).
Improvements include:
- Removing and replacing the pavement on the east and westbound lanes of I-90
- Removing and replacing concrete bridge approaches to provide a smoother transition from the roadway to the bridge
- Replacing the median concrete barrier rail, guardrail, and rumble strips
- Removing and replacing the pavement on interstate on- and off-ramps, as well as adjacent crossroads
- Applying a seal and cover (chip seal) to the new pavement
- Adding new paint markings and signage
- Installing weather-activated flashing lights at four overpass bridges
What to Expect during Construction
For the safety of the public and construction crews, MDT encourages motorists to plan ahead, allow extra travel time, slow down, and use caution when traveling through work zones.
- Traffic will be reduced to one lane in each direction where work is taking place.
- There will be brief delays of up to 30 minutes on I-90 on- and off-ramps as new pavement is placed near the merge points.
- Delays on mainline I-90 will be limited to speed reductions.
- Delays of up to 15 minutes are anticipated on crossroads during paving operations.
- Flaggers or temporary signals may direct traffic on ramps and crossroads.
- Interchange on- and off-ramps within the project area will be temporarily closed for the replacement of cattle guards, paving, and chip sealing work. To minimize inconvenience, MDT will close only one interchange ramp at a time. Detour routes will be provided.
- Width restrictions may be in place throughout construction. Visit 511MT.net for the latest information on width restrictions.
Stay Informed
MDT will notify the public about traffic and construction impacts through the project website, local media, social media, and email and text notifications. See the side panel to sign up for construction updates.
