6th Street NW/SW Roadway Resurfacing - Project Updates

May 12, 2025

On the 6th Street NW/SW Roadway Resurfacing project in Great Falls, northbound traffic remains shifted to the southbound lanes just past the Sun River Bridge. This crossover traffic pattern will stay in place while work continues. Please watch for cones, yield signs, and crews as you travel through the crossover.

Gas line replacement is now underway and will require temporary detours.

• While crews work near 9th Avenue SW, traffic will be detoured to 10th Avenue SW.
• As crews move to 10th Avenue SW, traffic will be detoured to 9th Avenue SW.

The south intersection of 6th Street SW and Crescent Circle is now closed for storm drain installation. Please use alternate routes and watch for updates.

Crews have also started repair work in the northern section of the corridor, on 6th Street NW. Expect single-lane closures with crews and equipment present. Only one lane will be closed at a time to maintain traffic flow.

May 5, 2025

Construction continues on the 6th Street NW/SW Roadway Resurfacing project between 10th Avenue South and American Avenue. This is the only active work zone in the project area at this time.

Crews have started removing the concrete pavement, and northbound traffic has shifted onto the southbound lanes just past the Sun River Bridge. This crossover will remain in place for the foreseeable future while work continues on the northbound side. Please follow all posted signage and use caution in the work zone.

Over the next several days:

• Concrete removal will continue heading south.
• Gas line replacement is expected to begin.
• The south intersection of 6th Street SW and Crescent Circle may temporarily close for storm drain work. Watch for signage and crews in the area.

Surveying may continue along other parts of the corridor to prepare for future repairs.

Looking ahead to the week of May 12, resurfacing work may begin in the other sections of the corridor. We will provide more details as work progresses.

April 28, 2025

This week, work will continue on the 6th Street NW/SW Roadway Resurfacing project, with crews focused on the section between 10th Avenue South and American Avenue. This is the only area currently under construction.

Crews will begin breaking pavement and removing medians in this section of the project. Northbound and southbound traffic patterns will initially be unchanged, but single-lane restrictions will be in place and may change daily. Please watch for cones and signage.

You may also see crews surveying in other parts of the corridor to prepare for upcoming repairs. Please drive carefully and watch for workers and vehicles.

A traffic crossover may happen as early as this Friday or Saturday. When it begins, northbound traffic will shift to the southbound lanes just after the bridge. This will become the long-term traffic pattern while crews work on the northbound side.

Thank you for your continued patience and safe driving as this project moves forward.

6th Street Traffic Control Starting April 22

Traffic-controlled work on 6th Street SW in Great Falls will start Monday afternoon, April 22. Crews will first close the right northbound lane and the east shoulder, starting at the Sun River Bridge and heading north toward American Avenue.

The old concrete will be saw-cut and then cracked for removal. During this work, the speed limit will be reduced to 30 miles per hour. Please watch for lane closures, signage, workers, and large equipment.

Later in the week, crews will saw-cut and crack the curbs on the southbound side and the center of the road to prepare for further work.

National Work Zone Awareness Week

April 21-25, 2025 | nwzaw.org [nwzaw.org]

Respect the zone, so we all get home.

In 2023, 282 work zone crashes occurred in Montana. This construction season, MDT urges Montana drivers and visitors to use extra caution while traveling through work zones by paying attention and following posted signage.

Our families thank you.
