Read News Release: I-41 Construction Begins
Project Location
Improvements will take place on 14.2 miles of I-41 between County D in Fond du Lac County and WIS 26 in Winnebago County.
Project need
The existing pavement and cable guard system (in the median) are both beginning to deteriorate and reach the end of their service life by the time of construction. The guardrail (bridges and ramps) will also be replaced to meet current safety standards. Drainage measures are needed to prevent water overtopping I-41 north of County Z to Black Wolf Avenue in the town of Nekimi, southern Winnebago County. A box culvert replacement will improve drainage.
Construction Scope
- Mill and overlay two (2) inches of asphalt in both lanes of I-41 in the project limits
- Replace cable barrier and guardrail along I-41 mainline and ramps
- Cable barrier protects motorists who cross into the median.
- Guardrail protects vehicles that run off the roadway at ramps, bridges and other locations with steep embankments.
- Miscellaneous structure maintenance work
- Miscellaneous culvert extension and slope flattening work
- Replace existing box culvert to address flooding issue north of County Z
