Project overview

WIS 65 is an arterial highway route serving St. Croix County and serves a high number of residents that commute to and from employment in the Twin Cities Metropolitan area.

Beginning in spring of 2012, WisDOT is planning several improvement projects on WIS 65 and I-94 in St. Croix County, which has been divided into two projects:

Project one

Reconstruction of WIS 65/I-94 interchange and two mile segment of I-94 addressing the deteriorating structural condition of WIS 65 bridge over I-94.

• Bridge is at the end of its lifespan and is in need of replacement
• Due to the large increase in vehicle traffic using the WIS 65 interchange, the ramps will also be reconstructed along with the new structure to better handle the increased traffic volumes
• I-94 to also be reconstructed in the area of the interchange to expand the median to meet the new standard of 60 feet
• Grading to also occur to construct the subgrade to support a 3rd lane in each direction to handle traffic in the future when volumes warrant adding a lane
• Lastly, the hill on I-94, just west of WIS 65 interchange, to be lowered to meet current standards and help provide a safer roadway

Project two

Series of four smaller project intersections that have experienced an elevated crash rate. Each was analyzed for safety improvements:

• WIS 65/County G
• WIS 65/US 12/120th Street
• WIS 65/US 12/130th Street
• WIS 65/County TT

Conclusion of the safety study was to reconstruct each intersection as a modern roundabout. Construction of modern roundabouts at each location will improve safety and improve capacity of the intersection to handle future traffic volume increases and decrease travel time and travel delay at each intersection.

Project cost estimated at $8 million.

Status/phase

Construction started spring 2012. Roundabouts anticipated to be completed Nov. 2012 and interchange reconstruction anticipated to be complete early summer 2013.
