The reasons why I-41 Near Kaukauna is seeing more closures in 2026
The rise in traffic disruptions is directly tied to the continuing I-41 Expansion Project, one of Wisconsin’s biggest transportation projects.
Temporary lane shifts, width reductions, limited maneuvering space, and counter-directional traffic have been created due to construction between Appleton and De Pere. These conditions can cause accidents to be more disorienting and can also take longer to clean up.
Significant construction related effects are:
- Counter-direction traffic from County J to County S (April-November 2026)
- Narrow shoulders (Ongoing)
- County U closure near ramps (April 27-Early July 2026)
- WIS 96 NB ramp closure (through Fall 2026)
- Richmond Street overpass closure (through Fall 2026)
- Nightly lane closures (8:00 PM – 5:00 AM)
Construction sites are tight spaces that do not allow for emergency vehicles or tow trucks to move around, even minor accidents and collisions can cause serious delays.
