Public Involvement
WisDOT hosted a public involvement meeting on November 21, 2024 at the East Troy Village Hall to discuss the proposed improvements. Materials and exhibits shared at the meeting are posted below.
As the project continues to move forward, your input is welcomed and appreciated throughout the design process.
Traffic Impacts
I-43 will remain open with staged construction. Crossovers will be used to maintain flow of traffic along I-43. Temporary ramp closures will be needed to accommodate ramp construction. Any ramp closures will include posted detours.
Schedule
Construction is tentatively scheduled to begin in fall 2026.
