LEWISTOWN, Mont.: The Montana Department of Transportation (MDT) and its partner, Kiewit, are resuming construction on the MT 200 Bridges Lewistown Area project. Crews have begun final work on the bridges over Parr Creek (5990 on map) and North Fork McDonald Creek (5994 on map).
Once work on the bridges is complete, paving operations will begin, followed by the application of a seal and cover (chip seal) and reflective epoxy striping at each site.
Motorists traveling through the project area should expect reduced speeds, single-lane traffic, temporary traffic lights, and possible delays.
In 2025, crews completed most bridge and culvert construction, setting the stage for final work and paving this season.
This project includes reconstructing ten bridges along US 87/MT 200 in the Lewistown area and replacing the aging structures with new bridges or culverts. Construction began in April 2025 and is expected to continue through summer 2026.
