The project will reconstruct and expand 23 miles of I-41 from four to six lanes between WIS 96 (Wisconsin Avenue) in Appleton to County F (Scheuring Road) in De Pere.
The project will reconstruct one system interchange between the Interstate and WIS 441, and 10 service interchanges including ramp work at the I-41 interchanges with WIS 96 and WIS 441/OO. WisDOT will also build a new service interchange at I-41 and Southbridge Road.
The project also includes replacing the Wrightstown Safety and Weight Enforcement Facility with a new building, which will also function as headquarters for the Northeast Region of the Wisconsin State Patrol.
Before the I-41 Project was approved for construction, WisDOT developed and studied multiple alternatives to reduce congestion, and update the roadway and bridges to meet current design standards.
WisDOT factored feedback from the public, tribes, businesses, agencies and local governments during the evaluation, which assessed each alternative’s ability to address the project’s purpose and need, and its potential environmental impacts, required right of way, and estimated cost.

Diverging Diamond Interchange
A diverging diamond interchange configuration best addresses traffic operations and improves safety with minimal impacts.
55 mph Flyover Ramp
The 55 mph flyover ramp alternative requires less land, has fewer impacts and costs less than a 60 mph flyover alternative while offering similar operational and safety benefits.
Diamond Interchange with Roundabouts
A diamond interchange with roundabouts will best handle future traffic volumes and produce fewer impacts than relocating the frontage road.
Diamond Interchange with Roundabouts
The I-41 project will construct a new diamond interchange with roundabouts, which has the best operational performance and meets safety and design standards, at I-41 and Southbridge Road/Orange Lane.

Auxiliary Lanes
An auxiliary lane is an extra lane added between interchange on- and off-ramps. It is used to ease speed changes, balance the traffic load, and provide an efficient way to weave into and out of traffic while lessening congestion in the through lanes.
Locations (5):
From WIS 96 to WIS 15
From WIS 47 to County E
WIS 441 from I-41 to County OO
From WIS 55 to County J
From Southbridge Road Interchange to County F
Auxiliary lanes will be built between these closely spaced interchanges in addition to a third travel lane that will be built as part of the I-41 Mainline improvements.
Collector-Distributor Road
Location (1):
From County E to WIS 441
A collector-distributor or C-D road will improve safety, requires less land and is less expensive than the alternatively considered braided ramp option, while providing a safe connection with acceptable traffic operations.
