2024 Proposed Road Projects  


Pioneer Road Closure

Effective April 18, 2024, Pioneer Road will be closed for reconstruction from CTH II to Larsen Road.     


CTH II Mill and Pave Project  - May 28 through June 7, 2024

Beginning Tuesday, May 28th, the Winnebago County Highway Department will be milling and paving CTH II from Clayton Avenue to CTH CB. During this time, traffic will be restricted to a one-way eastbound direction only.  Weather dependent, milling will occur during the week of May 28th.  Traffic will be returned to a two-way pattern though the weekend. Monday, June 3rd, the one one-way pattern will resume with paving. The project is expected to be completed by Friday, June 7th. 



I-41 Improvements in Winnebago & Outagamie County starting April 1, 2024

The WisDOT announced that they have hired a contractor for a maintenance project along I-41 between Breezewood Lane and WIS 96 for numerous pavement and structure related items.  Construction will include concrete pavement repair and diamond grinding of mainline I-41 and service interchange ramps, replacement of bridge approaches, existing beam guard, deteriorated metal culvert pipes and median inlets. The project begins Monday, April 1, 2024 and is expected to finish in early November of this year. The benefit of this project is to extend the life of I-41 bridges and pavement.  Drivers can expect significant traffic impacts through the entire project and motorists are advised to use alternate routes whenever possible.  Note: this project is separate from the I-41 major project between Appleton and De Pere.  For more information you may call the WisDOT at 920-492-5743.

Construction is scheduled from May 28, 2024 to October 1, 2024. 

TRAFFIC IMPACTS: Both directions of I-41 will be reduced from three lanes to two lanes across the bridge. The southbound I-41 on-ramp from US 45 will be closed for the majority of the project.

2024 National Work Zone Awareness Week was April 15-19, 2024

Please watch this video to learn about Work Zone Safety:


Work Zone Safety

Each year in Wisconsin, both highway workers and motorists are killed and injured in crashes that happen in highway construction zones. Motorists should slow down, be patient and pay attention to their surroundings in all work zones.

For more information regarding work zone rules for motorists, the law restricting hand-held devices, and general work zone safety information, please see WisDOT's work zone safety website.  To help safeguard law enforcement officers, emergency responders, road maintenance workers, and others who work on the side of the highways, Wisconsin has a "Move Over Law" (Wis. Stat. s. 346.072) stating that drivers must provide a safety zone for stopped law enforcement, emergency and maintenance vehicles.

The law requires drivers to shift lanes or slow down in order to provide a "safety zone" for a squad car, ambulance, fire truck, tow truck, utility vehicle, or highway maintenance vehicle that is stopped on the side of a road with its warning lights flashing.

Drivers have two options for creating a safety zone:

  • If the road has more than one directional lane, like the Interstate, and you can switch lanes safely, you must move over to vacate the lane closest to the law enforcement or other vehicle with its lights flashing.

  • If the road has a single directional lane or you can't safely move over, you must reduce your speed.

Failure of motorists to move over is one of the reasons that motor vehicle crashes kill more law enforcement officers on duty than any other cause.

WisDOT Announces Project on WIS 116 in Winnebago County

The Department of Transportation is planning a resurfacing project along WIS 116 from the east village limits of Winneconne to US 45.  The project will extend for roughly 6-7 weeks sometime between July 2024 and October 2024.  While WIS 116 will remain open to traffic, you can expect some delays. There will be daytime single lane closures and flaggers directing traffic around the work zone.  For more information on this project you may visit the WisDOT website at: https://projects.511wi.gov/weeklyupdates-ne/2024-annual-construction-advisory/



Winnebago County held a public involvement meeting on Tuesday, August 29, 2023. The purpose of the meeting was to discuss the proposed reconstruction project along CTH "P" from Wis 47 to Midway Road.  Discussion was focused on the preliminary design concepts for the reconstruction of the roadway and to gather public comments about the proposed project.  The project is currently planned for construction in the summer of 2025.  If you would like information, please contact design consultant Andy Dana at 920-498-1200. Written comments regarding the project may be mailed to Andy Dana, Ayres Associates, 3376 Packerland Drive, Ashwaubenon, WI 54115 or email to danaa@AyresAssociates.com.



The Winnebago County Highway Department is proposing a reconstruction project along CTH "I" (Oregon Street) from south of Ripple Avenue to Waukau Avenue. The project is proposing to improve 1.2 miles of CTH I, including modernizing it to an urban two-lane roadway with a center turn lane, bike lanes, and new concrete pavement. Storm sewer will also be added and upgraded within the project limits to improve drainage and address flooding issues. The project is scheduled for 2024.

 Any questions or comments on this project can be addressed to Rowland Hoslet, PE, EXP U.S. Services, Inc. at 920-857-6304 or Rowland.hoslet@exp.com.   



The Wisconsin Department of Transportation announced proposed updates to the Main Street (US 45) Bridge in the City of Oshkosh. The purpose of the project is to preserve the operation of the structural, mechanical, and electrical components of the bridge.   Construction is anticipated to begin in the fall of 2025.  The structure is currently safe for vehicle and pedestrian crossing.   For more information on this topic: Main Street Bridge Proposed Improvements. 



The Wisconsin Department of Transportation has a project planned for the WIS 44, Wisconsin Street bridge.  Work will include removing the deteriorating paint system and repainting the structural steel members of the bridge, as well as replacing the gate arms.  Construction is currently scheduled for 2026. For more information on this project, you may visit the WisDOT website at:  https://wisconsindot.gov/Pages/projects/by-region/ne/44oshkosh/default.aspx.



The existing bridge was constructed in 1956 and is nearing its service life.  The Wisconsin Department of Transportation (WisDOT) determined in April of 2021, based on a bridge inspection, that several issues need to be addressed.  Construction is scheduled for summer of 2028.
