I-41 Project

What’s happening NOW on I-41?

Construction on I-41 is well underway. The next phase involves the closure of the County N interchange and the bridge over I-41, starting June 20, 2024. This reconstruction project is scheduled to be completed by the fall. Check out the construction page for more details.

The existing County N interchange configuration will remain, with some modifications to turn lanes to accommodate additional traffic.

Work zones are a sign to slow down. Keep an eye out for orange signs, construction barrels, flags, workers or flashing lights during construction to keep everyone safe.

Road construction will begin in early 2024 and will impact multiple interchanges and overpasses. Click here to view more I-41 Project construction information.

WisDOT and Wisconsin Department of Natural Resources (WDNR) staff coordinate regularly during transportation project development.

The I-41 Project team hosts public involvement meetings to share updates and interact with the public, businesses, and local and elected officials.

Professional surveyors take measurements along the corridor, which will provide topographical data used for project planning, design and construction.

Professional surveyors use maps and magnetic locator tools to identify underground survey markers and property pins.

Soil investigations reveal the types of soil, bedrock depth and groundwater conditions upon which roadway structures will be built.

To obtain samples, licensed operators drill to various depths depending on the type of structure expected in a given location.

Engineers analyze the results of the soil samples when designing the roadways, bridges and other structures for the project.

Design/Traffic Management

Tasks in the design phase include finalizing plans and specifications; appraising and acquiring real estate; relocating utilities; finalizing engineering cost estimates; planning and coordinating traffic management and incident response with local municipalities, law enforcement, and emergency responders; and engaging and informing the public about work in the corridor.

Real Estate

Strengthening our highway system requires that WisDOT carefully manage and sometimes acquire the real estate – or right of way – that surrounds it. This property can include land, homes and businesses. Tasks related to real estate work can include property appraisals, negotiations and relocations, and topographic surveys or layouts of proposed impacts to right of way.

Utilities

Almost every highway construction project must address utilities, which are often located within or adjacent to the highway right of way. Tasks related to utilities work can include the relocation, replacement or adjustment of utility facilities that use the path of the highway.

Construction

In addition to the obvious – constructing the project – other tasks during this phase include advertising and evaluating bids from contractors; awarding various work contracts; and continuing coordination and communication with local officials, residents, businesses, utility owners and other state agencies.
