I-41 Project

What’s happening NOW on I-41?

Throughout 2023, WisDOT will continue developing the final design plans and construction staging plans for the anticipated 2024 start of construction.

Crews will continue topographic and archaeological surveys as well as geotechnical/soil investigations for the rest of 2023. Real estate negotiations and utility relocations will also begin this year.

Keep an eye out for the next round of public involvement meetings this summer, at which time we plan to share the updated designs and the construction schedule information.

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

In-ground surveying points are used as a datum for the measurements that engineers use for roadway design.

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

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.

Wisconsin Department of Natural Resources (WDNR) staff perform a field review of culverts and stream crossings around the I-41 Project area. WisDOT and WDNR staff coordinate regularly during transportation project development.

The I-41 Project team hosts public involvement meetings to share information and interact with the public, community and stakeholder groups, businesses, and local and elected officials in the project area.

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.
