MARINETTE COUNTY

 

WIS 180, Culvert Replacements

Location/Limits: WIS 180 from WIS 64 to USH 141.

Length: 29 miles

Schedule: Project starts July 20, 2026, and is expected to finish in late October of 2026.

Cost: $3.74 million

Description of work: This culvert replacement project includes removal of 42 deteriorating culverts and installation of new culverts, removal and replacement of associated beam guard and pavement at pipe culvert locations, minor grading at pipe culvert endwalls.

August 31 to September 4: Expect multiple construction crews working throughout the WIS 180 corridor between County X and Wausaukee this week. A long-term, full closure is anticipated for the large box culvert being replaced roughly 1.5 miles east of County XX. Smaller pipe culverts will also be replaced during this time starting just south of County JJ and working towards the intersection of Forest Road. These pipes may also require periods of full closure, but the contractor is aware that access needs to be always maintained to local traffic from at least one direction. If there are no alternative routes around, they may be required to do some of these pipes in halves, letting local traffic around. On Wednesday of this week the contractor anticipates moving up to the pipe located roughly 1/3 of a mile west of Kujawa Road which will require full closure. It’s anticipated that this pipe will take all day to complete. Once this pipe is completed, they will pick back up from where they left off and continue replacing pipes while working westward. Various other crews will be found working between County X and Wausaukee throughout the week so expect other potential delays outside of what’s listed above.

September 8 to September 11: Much like the week prior expect multiple construction crews working throughout the WIS 180 corridor between County X and Wausaukee. A long-term, full closure will still be in effect for the large box culvert being replaced roughly 1.5 miles east of County XX. It’s anticipated that this box culvert could take upwards of three more weeks to complete. Smaller pipe culverts will be replaced during this time starting around Kujawa Road and working towards the intersection of Mud Lake Road. These pipes may also require periods of full closure, but the contractor is aware that access needs to be always maintained to local traffic from at least one direction. If there are no alternative routes around, they may be required to do some of these pipes in halves, letting local traffic around. It’s anticipated that earthwork crews will be busy prepping for paving during this time as well between County JJ and roughly 1.5 miles east of County XX. It’s also anticipated that paving crews will be on site paving back culvert patches between County X and County JJ on Tuesday and Wednesday of this week.

Traffic Impacts:

WIS 180 will be closed to thru traffic and detoured in two separate stages during culvert replacement beginning July 20, 2026.

• Local access will be maintained for businesses, properties, and emergency services within the project work zone.
• Brief temporary interruptions in driveway access (typically one to two hours) may occur, and the contractor will notify affected homeowners and businesses in advance.

Stage 1 Detour (starting July 20, 2026):

• For culverts south of County X, traffic will be detoured via US 141 and WIS 64.

Stage 2 Detour (starting mid-August 2026):

• For culverts north of County X, traffic will be detoured via US 141 and County X.
