6th Street NW/SW Roadway Resurfacing - Project Updates

July 7, 2025

The Montana Department of Transportation (MDT) and Ti-Zack Concrete continue construction to rehabilitate the 6th Street NW/SW corridor. Traffic remains shifted to the newly paved northbound lanes, and this configuration will remain in place for the time being, with no changes to traffic control currently planned.

Crews are continuing to repair the roadway and beginning median work and joint sealing. Median work will take place only in the reconstructed section of the project. Joint sealing will occur across the entire project area and require single-lane closures in both directions.

Repair work on Fox Farm Road is anticipated to begin the week of July 14.

On 6th Street NW, between American Avenue and the NW Bypass, single-lane closures and reduced speed limits remain in effect. The location of active work zones will continue to shift throughout the week.

As always, work is dependent on weather and unforeseen circumstances. Thank you for staying cautious and watching for signage and crews in the work zone.
