Project overview

  • Expand 11 miles of WIS 15 to a 4-lane divided highway bypassing village of Hortonville. This project will increase safety, enhance economic development and lower transportation costs in the region.
  • Roundabouts are planned at the two locations, one on each side of Hortonville, where proposed bypass meets existing WIS 15.
  • WIS 15 is a busy commuter route between New London and Fox Cities area. WisDOT studied WIS 15 to determine the best way to provide additional roadway capacity and improve operational efficiency and traffic safety.
    • Insufficiencies in roadway structure, as well as geometric and intersection design, are creating an increased number of safety issues.
    • Capacity must be added to serve existing and forecasted traffic volumes. Heavy congestion is expected by 2025 if WIS 15 is not expanded.
    • WIS 15 to be expanded to 4-lane divided highway.
    • At-grade intersections to be constructed at the two points where the proposed bypass meets existing WIS 15.
