MENOMONIE, Wis. — The Dunn County Highway Department is undertaking several roadway and bridge improvement projects during the 2026 construction season, focusing on pavement rehabilitation, drainage improvements and long‑term roadway durability. 
“The Dunn County Board of Supervisors has made a major investment to improve the county’s roadways,” said County Highway Commissioner Dustin Binder. “This work represents a continued investment in maintaining safe and reliable transportation routes for residents, businesses and visitors.” 
 Projects scheduled for this summer include: 

  •  Highway E (I‑94 to Highway 40): Crews will replace several deteriorated culverts, pulverize the existing roadway and repave the 6.69‑mile segment with new pavement. Work is expected to begin in April or May. 
  •  Highway I (Sand Creek to the Barron County line): This 3.56‑mile project will replace all culverts, widen shoulders, complete ditching, add base materials, pulverize the existing roadway and repave. Construction is scheduled to start in May. 
  •  Highway C (Highway Z to Highway D): Work on this 2.41‑mile segment will include replacing all culverts, ditching, adding base materials, pulverizing the existing roadway and repaving. The project is scheduled to begin in June. 
  •  Highway N (Highway M to Highway A): Crews will replace all culverts, widen the roadway, complete ditching, add base materials, pulverize the existing roadway and repave the 3.27‑mile segment. Work is expected to start in July. 
  •  Highway Q/Wilson Creek Bridge (Project P17‑936): The contractor will remove and replace the existing bridge structure. Work is currently scheduled to begin in June. 
  •  Highway D/Red Cedar River Bridge (Project B17‑078): Rehabilitation work will include a concrete deck overlay, abutment repairs, replacement of approach guardrail and installation of scour countermeasures around bridge piers. The project is scheduled for this summer. 

Binder noted that several state highway projects will also take place in Dunn County this year, including work on Highway 40 from Elk Mound to Colfax; Highway 25 from I‑94 to Highway D; and Highway 85 from Highway O to the Eau Claire County line. Those projects are managed by the Wisconsin Department of Transportation, and detailed schedules are not yet available. 
 “We appreciate the public’s patience as these improvements move forward,” Binder said. “Construction work is necessary to keep our transportation network in good condition, and motorists should expect occasional delays and plan extra travel time.” 
All schedules are subject to change based on weather and contractor availability. Motorists are encouraged to use caution in work zones and follow posted detours and traffic control. 
The county worked on 8.18 miles in 2021; 10.68 miles in 2022; 13.49 miles in 2023; 12.28 miles in 2024; and 16.07 miles of road work in 2025. The 2026 schedule calls for 17 miles of road work. 
County officials say it costs approximately $150,000 to resurface a mile of roadway, while pavement replacement costs $250,000-$300,000 a mile.  Reconditioning costs $400,000 to $500,000 a mile, and total reconstruction costs $1 million or more a mile. Roads have a lifespan of 20 to 25 years.
