The Montana Department of Transportation (MDT) and its partner M.A. DeAtley Construction, Inc., has begun initial site preparation, including dirt work and staging. This work is expected to continue until April.

Minimal traffic disruption is anticipated until April and much of the work will be off-site and not seen from the road.

While traveling through the project site, please be mindful of the speed limit as well as the large trucks and other equipment in the area.

Following site preparation in April, full construction activities are anticipated to begin and continue through the 2025 construction season.
