KALISPELL, Mont. – The Montana Department of Transportation (MDT), in partnership with Stillwater Electric Inc. and Knife River, announces construction at the intersections of U.S. Highway 93 (US 93) with Treeline Road (Project #1) and Wyoming Street (Project #2) beginning this summer. These intersection improvement projects will enhance safety and accessibility.

Nighttime construction is scheduled for the following dates, weather and other unforeseen factors permitting:

  • US 93 with Wyoming Street (Project #2): starting the week of July 28
  • US 93 with Treeline Road (Project #1): starting the week of August 11

Construction will take place during nighttime hours, from 7 p.m. to 7 a.m., to minimize disruptions and traveler impacts. Approaches to both Treeline Road and Wyoming Street will be closed from 8:30 p.m. to 7 a.m. US 93 will be reduced to one lane in each direction with traffic control in place, and flaggers will be on-site to assist trucks entering and exiting the work zone. Drivers should stay alert, follow posted signage, and use caution near construction areas. Pedestrians, cyclists, and motorcyclists are encouraged to consider alternate routes.

“These intersection projects are set to enhance accessibility and operations for drivers and pedestrians,” said Bob Vosen, MDT District Administrator. “MDT recognizes the vital need for enhanced safety and access for all users.”

Intersection improvements include aligning dedicated left turn lanes, adding permanent pavement markings, and upgrading sidewalks and ramps to enhance safety features and meet Americans with Disabilities Act (ADA) requirements.

“MDT and Knife River are pleased to be collaborating on these intersection projects that will greatly benefit our community,” states Kurtis Paulson, Project Manager for Knife River. “We look forward to being a part of a project that will improve the local infrastructure and enhance roadway safety.”
