I-94 Interchanges Study - Hudson, St. Croix County


I-94, from State Line to east of US 12 including I-94/Carmichael Rd. and I-94/US 12/WIS 35 interchanges, in Hudson, St. Croix County.


A study is being conducted to improve portions of I-94 to accommodate for an increase of traffic in future years. Significant system improvements are needed to produce efficient traffic flow.

Traffic growth in the study area and surrounding communities will result in traffic volume increases of 40-80% by year 2035 on I-94, Carmichael Road, and US 12. This additional traffic will generate traffic operational problems at the Carmichael Road and US 12 interchange areas.

Improvements are needed to accommodate:

  • The 70/30 split of directional traffic volume on I-94
  • Closely spaced intersections of 400 to 700 feet on Carmichael Road
  • Heavy truck volumes of 10-20% of total traffic on US 12
