Lincoln - Applegate Intersection logo

May 29, 2026

The Montana Department of Transportation (MDT) and Hoffman’s R&M Services LLC have completed work building a detour for the Lincoln Road and Applegate Drive intersection. Crews will begin excavation of the center of the intersection and work on the southern leg of the roundabout the week of June 1. Traffic on the southern leg of Applegate Drive will be in a single-lane configuration during working hours, 7 a.m. to 6 p.m. Monday through Friday.

Starting the week of June 1, the intersection will enter a "no left turn" state. Additionally, north/south traffic on Applegate Drive will no longer be able to go straight through the intersection and will need to keep right when entering the intersection. If you commute through the intersection via Applegate Drive and typically turn left or go straight through the intersection, you should plan an alternate route accordingly.

East/west traffic on Lincoln Road will continue to use the intersection detour.

During construction, motorists should expect:

  • Reduced speed limits
  • Single-lane traffic
  • Traffic controlled by flaggers or temporary signals
  • Width restrictions at times
  • Possible short-term closures

Work on this project is anticipated to be completed in a single construction season.
