Project overview

  • Extends approximately 3.5 miles.
  • Identify the preferred alternative for converting US 12/18 from a 4-lane expressway to a 4-lane freeway.
    • An expressway is a high-speed divided highway with partial access control. At-grade intersections, median crossovers, and some driveways are allowed.
    • A freeway is also a high-speed divided highway, but direct access is allowed only at interchanges.
  • Overpasses and frontage roads are used to provide connections for local traffic and to direct vehicles to the interchanges.
  • Possible alternatives include:
    • Addition of interchanges
    • Grade-separated overpasses
    • Frontage roads to connect local roadways
  • Alternatives will be evaluated to determine the level of safety improvement, costs, right of way needs, land use, and environmental and local impacts.
  • Evaluate the impacts of converting US 12/18 to a freeway and prepare an Environmental Assessment to document the impacts.
  • Identify right of way needs for the recommended alternative and preserve and map the corridor under Wisconsin State Statute 84.295.​
