Road, bridge work resumes in Northwest Montana

The Montana Department of Transportation, along with partner Sletten Construction Companies, are resuming work rehabilitating 11 bridges on Highway 37 next week. 

Construction activities on this multi-year project are anticipated to be completed this fall.

Work will resume at the bridge located at mile marker 37.9, that crosses over Sheep Creek. Crews are scheduled to begin working the week of Monday, April 13, from 6 a.m. to 9 p.m.

Travelers should expect 10- to 15-minute delays, reduced speeds and single-lane traffic when traveling through the project area. There is a 10-foot width restriction through the project area. Wide loads will need to find an alternate route. For the most up-to-date width restrictions and road conditions, visit 511mt.net.

MT 200 bridge preservation activities to begin

MDT, along with partner Hamilton Construction Company, will begin to rehabilitate the bridge that spans the Clark Fork River on Highway 200, one mile west of Thompson Falls.

Work is scheduled to begin the week of April 13. Crews will be working from 7 a.m. to 8 p.m. Monday through Saturday.

Automated traffic signals directing alternating single lane traffic will be in place. Wide loads, over 10 feet in width, must find an alternate route. 

Work to replace I-90 bridge over Clark Fork River

As part of the Clark Fork River/Old Highway 10 Bridges project, MDT, along with construction partner Sletten Construction Companies, will begin work to replace the westbound bridge that carries Interstate 90 (I-90) over the Clark Fork River, approximately 9.5 miles west of Alberton, this spring. 

Completion is anticipated in fall 2027. 

During construction, Old Highway 10 West will be closed to the public between the Tarkio East Fishing Access and the Triple Bridges – Alberton Gorge Recreational Access point, restricting access to the east bank of the Clark Fork River. 

This section of the Clark Fork River will remain open for recreational use during the 2026 construction season. The public is not permitted to enter the recreational area closure at any point to access the Clark Fork River. At this time, Tarkio East Fishing Access Road will remain open to the public.

Updates on this project can be found on the MDT website mdt.mt.gov/pubinvolve/i90alberton/.

Crews to begin I-90 reconstruction project near Taft

MDT, along with construction partner Knife River, Inc. – Mountain Division, will be reconstructing about 3.5 miles of Interstate 90, beginning at the Montana/Idaho border heading east. The I-90 Lookout Pass to Taft project is expected to take two 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.

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.
