TAFT, Mont. - The Montana Department of Transportation (MDT), along with construction partner Knife River, Inc. – Mountain Division, will be reconstructing about 3.5 miles of Interstate 90 (I-90), beginning at the Montana/Idaho border heading east. The I-90 Lookout Pass to Taft project is expected to take 2 construction seasons to complete, with work this year occurring in the eastbound lanes.
This project will replace deteriorating pavement with new and more durable concrete, as well as provide:
- Safety enhancements at the Lookout Pass Interchange.
- Surface drainage upgrades and culvert replacements.
- Concrete barrier replacement.
- Roadway lighting and signage updates.
The purpose of the I-90 Lookout Pass to Taft project is to extend the interstate’s service life and enhance roadway safety features.
When traveling through the project area, motorists should expect reduced speeds, single lane traffic, and lane shifts with crossovers, so all traffic travels in the westbound lanes through the project area. Traffic may be routed onto the interstate shoulder when work is occurring.
Wide loads of 12 feet or more must be staged and will be allowed to travel through the project area between 7 a.m. to 9 a.m. Mountain Standard Time Monday through Friday. Wide loads may contact Poteet Construction at 406-360-8187 to schedule passage.

This project is anticipated to begin the week of April 13. Updates for this project can be found on the MDT website mdt.mt.gov/pubinvolve/i90lookout/.
