  • The roadway is open to business, properties and emergency services in the work zone.
  • The roadway is closed to through traffic only… if you do not have a destination in the work zone, please use the detour route to help keep workers safe.

Project purpose and need

The WIS 42 existing pavement is showing signs of deterioration. The existing beamguard has reached the end of its useful life and the metal culvert pipes under the highway are deteriorating. The bridge deck on the West Twin River bridge is nearing the end of its service life.

Project improvements

This is a resurface-level project with bridge deck and culvert work. Construction includes:

• Mill 2.5 inches of the existing surface and pave 2.5 inches of hot mix asphalt
• Concrete bridge deck overlay (West Twin River Bridge)
• Culvert replacement and cleaning
  • View culvert locations on a map (pdf)
• Concrete base patching
• New curb ramps built to ADA standards
• Beamguard replacement
• Mirro Drive intersection realignment (closer to 90 degrees. Photo on right)
• Pavement marking

Construction benefits

Resurfacing will provide a smoother ride for motorists, extend the life of the pavement, and decrease future maintenance costs. Culvert repairs/replacements will help ensure proper drainage and lessen the likelihood of collapse. Mirro Drive realignment will provide a safer turning and crossing movement. Bridge overlay will extend the life of the bridge. Beamguard upgrades will provide a greater level of safety should impact occur.

Traffic impacts

WIS 42 will be CLOSED AND DETOURED to through traffic from April 1, 2025, through May 23, 2025, for bridge deck work and culvert replacements.

• Detour: Motorists will be directed to use US 10, County B, and WIS 310.
  • View WIS 42 detour on a map (pdf)
• Access to businesses and properties in the closed portion of the highway will always be maintained.
• Some closures will require approaching from the north or south on WIS 42 depending on location of culvert work.

During highway resurfacing operations following bridge and culvert work at the end of May, WIS 42 will remain open to traffic using lane closures and flagging operations to complete construction.

Schedule

Construction begins April 1, 2025, and is expected to finish in July 2025.

Temporary business signing

If business access is impacted by a closure or detour, temporary business signing may be placed by filling out a WisDOT business signing permit. All temporary business signing needs approval via the permit before placement to ensure it is in a safe location and does not pose a visual distraction or traffic hazard. The temporary business signing permit is free. Costs associated with creating the temporary sign are the responsibility of the business.
