Schedule: October 2025 to October 2026
Description of work: To build the new, I-41 overpass required for the Brown County South Bridge Connector, local frontage road realignment was completed as an initial phase of the project in 2025. Now that the realignments of the frontage roads are complete, the early filling material will sit in place to settle over the winter of 2025/2026. The contractor has made progress on temporary widening and the median bridge pier over the winter and continues until summer 2026. Other work on this contract includes 11 sign structures, box culvert extension, common excavation, roadway embankment, base aggregate, select crushed, concrete pavement, hot mix asphalt pavement, storm sewer, erosion control, signing, pavement marking, and all other incidental items necessary to complete the work.
September 21 to September 24: Lane shifts are in place along northbound and southbound I-41 to accommodate the construction of the additional auxiliary lane which will connect County EB-GV (Southbridge) to County F (Scheuring Road) and will be in place for until the end of October. The contractor has completed a significant amount of the grading with crews backfilling placing aggregate. The two south ramp tie-in work will begin and take several weeks to finalize with grading, aggregates and HMA paving. The bridge contractor will work on site cleanup, stripping form work, railing, fencing, staining and continue work on punch list items including stripping the form work under the bridge deck. Hand formed ancillary concrete items and pavement will be poured to finalize most of the interchange except for the southbound auxiliary lane. The remaining auxiliary lane work will take us through the end of the project. Fencing will be installed along the right of way along the entire project. Sign structures will be assembled for Type I signing and some electrical/ITS installations will be completed. On going traffic control maintenance, staking, restoration, and erosion control device management will be monitored. New installations of devices will occur as the impact footprint is expanded.
Sept 28 to Oct 2: Grading operations will be going for several weeks to complete the southbound auxiliary lane and both ramp tie-ins to mainline on the south half of the interchange. Scheuring Road southbound on ramp will close for 30 days to perform removals, grading, aggregates, paving, barrier wall and incidentals. The bridge contractor will work on site cleanup, stripping form work, railing, fencing, staining and continue work on punch list items including stripping the form work under the bridge deck. Electrical and ITS items will be installed throughout the project in various locations. Sign structures will be erected at several locations throughout the project. Overnight the contractor will set full closures for deck striping and to complete bridge punchlist items and median grading work as well. On going traffic control maintenance, staking, restoration, and erosion control device management will be monitored. New installations of devices will occur as the impact footprint is expanded.

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.
September 21 to September 25: 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 one and a half to two more weeks to complete. The large pipe replacement at McCall Lake intends to have completed enough of the roadway to allow traffic through but expect delay at this location for a week or more given other work that still needs to take place at this location. There are several pipe trenches between County XX and Wausaukee that still require work so expect some delay while this work takes place as well. At times this work may 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 this work in halves, letting local traffic around. Paving crews be on site Thursday and Friday focusing mostly on finishing the pavement between County X and the full closure located roughly 1.5 miles east of County XX.
September 28 to October 2: Once again 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 one and a half more week to complete. The large pipe replaced at McCall Lake will likely have multiple crews working in this area throughout the week as well, which may require times of full closure so expect delays or the need to find alternative routes around. There are several pipe patches between County XX and Wausaukee that will still require additional work this week so expect some delay while this work is taking place. Paving crews will be on site finishing the pavement between the full closure 1.5 miles east of County XX and Wausaukee.
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.
