The Montana Department of Transportation (MDT) construction project along I 90 between East Laurel and West Billings has begun!

Knife River will improve I 90 from the west bridge ends of the Mossmain Interchange to the east bridge ends of the West Billings Interchange bridges over King Avenue West. The project will include resurfacing the deteriorated roadway, the addition of roadway safety enhancements, widening the decks of the interstate bridges over South 56th Street West, resurfacing the remaining interstate bridges, and ADA compliance upgrades to the West Billings Interchange. The roadway safety enhancements for this project will include new rumble strips, guard rail, concrete median barrier, signage, and pavement markings striping throughout the project area.
