Project location

I-90/94 and WIS 82 Interchange, Mauston, Juneau County

Project overview

This project will reconstruct the entire I-90/94 and WIS 82 interchange. Major work items will include the replacement of the bridges over WIS 82 and the adjacent I-90/94 bridges over the Lemonweir River and County G. The interchange ramps and ramp terminals will be reconstructed, along with a portion of WIS 82 in the vicinity of the interchange.

Schedule

  • Construction is currently scheduled for portions of 2021-2023. 

Traffic impacts/detours

The first stage, scheduled to begin in 2021, will occur entirely on I-90/94, and will temporarily widen the existing westbound bridges and roadway and construct median crossovers in anticipation of replacing the eastbound bridges the following spring.

The second stage, scheduled for 2022, will move eastbound I-90/94 traffic over to the westbound side, running four lanes of counter-directional traffic. This will allow construction on the eastbound side of the Interstate including the eastbound bridges, eastbound ramps, and the eastbound lanes. The ramps will be staged to allow them to remain open at all times. WIS 82 will be reduced to one lane in each direction while the opposite side is being reconstructed. Access to driveway entrances and intersections will be maintained during construction operations. Pedestrian access will be limited to one side at a time. WIS 82 traffic will switch sides mid-way through the summer to reconstruct the other side. The majority of work on WIS 82 is anticipated to be completed in the 2022 construction year. County G (Sherman St.) will be closed temporarily under the Interstate bridges using a detour while the bridge foundations are constructed. The second stage work is anticipated to use most of the 2022 construction season. As winter arrives, the work will be suspended and eastbound traffic reverted to its normal side on the Interstate.
 
The third stage is anticipated to begin in the late winter or early spring of 2023. The third stage will move westbound I-90/94 traffic over to the eastbound side, running four lanes counter-directional traffic. This will allow construction on the westbound side including the westbound bridges, westbound ramps, and the westbound lanes. The ramps will be staged to allow them to remain open at all times. Traffic control on WIS 82 should be limited to short-term lane closures during bridge foundation work. County G (Sherman St) will be closed temporarily under the Interstate bridges using a detour while the bridge foundations are constructed. Construction on I-90/94 will most likely take the entire 2023 construction season.
