I-94 (WIS 35-US 12) - Hudson, St. Croix County


I-94, WIS 35 North to 0.85 miles east of the US 12/County U Interchange, WIS 35 South from Hanley Road to I-94 in St. Croix County.


We are currently planning to upgrade operations and safety of I-94 in Hudson. The proposed project would construct additional lanes between WIS 35 North and US 12/County U interchanges and build additional lanes on the ramps at the WIS 35 South interchange.

The proposed project would also replace the bridge decks of the I-94 structures over WIS 35 North and Front Street and construct an emergency crossover near the St. Croix River on I-94.

noise analysis was performed during preliminary design to determine the feasibility of noise abatement. Two noise barriers will be built with this project. More information about the analysis and location of noise barriers can be found here.

Why is the project needed?

The proposed project is intended to reduce congestion and provide efficient and safe access to I-94 for the ever increasing commuter traffic to and from the Twin Cities metro area.


Construction is planned to begin in the spring of 2017 and end in late fall of 2017.

Traffic Impacts

At this time we anticipate I-94 single lane closures during off-peak hours. Ramp closures will be needed at the WIS 35 North interchange to facilitate bridge construction. Detour routes will be provided.
