I-41 FROM APPLETON TO DE PERE

What’s happening NOW on I-41?

With the environmental study phase complete, the I-41 Project kicked off its design phase.

Crews are conducting land surveys and geotechnical/soil investigations along the corridor at all interchanges and along WIS 441 from I-41 to County OO (Northland Avenue). This work will be underway for the rest of 2022.

Please use extra caution as you travel through the corridor, as heavy equipment will be present on the roadway shoulders.
Professional surveyors take measurements along the corridor, which will provide topographical data used for project planning, design and construction.

Soil investigations provide information about the types of soil, bedrock depth and groundwater conditions upon which roadway structures will be built.
Geotechnical engineers extract soil samples that are analyzed and then factored when WisDOT designs the roadways, bridges and other structures.
To obtain samples, licensed operators use an auger to drill to various depths depending on the type of structure (such as a bridge or retaining wall) expected in a given location.

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.
