The Montana Department of Transportation and its construction partner, Ti-Zack Concrete, are continuing work on the 6th Street Northwest/Southwest roadway resurfacing project.
Beginning Aug. 4, 6th Street Southwest will be closed to southbound traffic between 10th Avenue South and 10th Avenue Southwest to allow crews to rebuild a section of the roadway.
This follows the completion of northbound work, which required a similar, temporary closure.
6th Street Northwest/Southwest closures planned for resurfacing project
“To safely and efficiently complete construction, MDT is using directional closures to limit traffic exposure in active work zones,” according to MDT.
During the southbound closure:
- all southbound traffic will be detoured. Drivers should use Central Avenue West to connect to Interstate 15 or seek alternate routes for traveling south across the Sun River.
- northbound traffic will reopen and local access will be maintained for residents, businesses, and emergency responders.
- nearby businesses remain open and accessible via detours, and 6th Street SW southbound is accessible until the intersection with 10th Avenue Southwest.
This closure is expected to last approximately two weeks, weather and other unforeseen factors permitting. Crews may work seven days a week to stay on schedule. Drivers should expect delays and plan ahead.

“Safety remains our top priority,” Jim Wingerter, MDT Great Falls district administrator, said in a release. “Maintaining one lane in each direction through this stretch would put both crews and drivers too close to active work zones. A full directional closure not only helps avoid confusion, particularly at night, but also enables us to complete this phase efficiently and with fewer disruptions.”
