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 began in August 2025 and is anticipated to 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 completed in 2025 included:

  • Removed and replaced the pavement on the east and westbound lanes of I-90
  • Removed and replaced concrete bridge approaches to provide a smoother transition from the roadway to the bridge
  • Replaced the median concrete barrier rail, guardrail, and rumble strips
  • Removed and replaced the pavement on interstate on- and off-ramps, as well as adjacent crossroads
  • Installed weather-activated flashing lights at four overpass bridges

Remaining work in 2026 includes:

  • Finishing guardrail work
  • Applying a new seal and cover (chip seal) to the new pavement
  • Adding new paint markings and signage

Remaining work is anticipated to take approximately 6 weeks to complete.

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 where work is taking place.
  • Delays on mainline I-90 will be limited to speed reductions.
  • 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 chip sealing work. 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.
