Project overview

This segment extends 13 miles along I-39/90, and is one of three segments of the I-39/90 Project.

Central segment to reconstruct and expand the Interstate to eight lanes, County O to WIS 26 interchange and six lanes, WIS 26 to Dane/Rock County line.

Interchanges within this segment (WIS 11, US 14, WIS 26 and WIS 59) to be reconstructed to address deficiencies. Grade separated crossings along the segment are also included in the reconstruction.

In 2010, an average of 50,000 vehicles per day used I-39/90 between County O and the Dane/Rock County line.
