I-41 Project

What’s happening NOW on I-41?

Starting Tuesday, May 6, 2025, the County J bridge over I-41 will close for construction. The on- and off-ramps at County J will also close in late June, with the interchange anticipated to reopen to traffic by late summer.

This project will include reconstructing the on- and off-ramps, replacing pavement, adding new bicycle and pedestrian accommodations, and improving the roundabouts to better accommodate oversize and overweight vehicles.

The project team thanks you for your patience and cooperation throughout this project!

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.

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.
