As part of the I-39/90 Expansion Project, the I-39/90 and County N interchange (Exit 147), north of Stoughton, will be reconstructed this year. Work on the new interchange will begin in late April. When completed this fall, the interchange will feature three roundabouts to improve safety and mobility in the area.

A public meeting was held on April 18, 2017 at the Stoughton High School cafeteria. View the exhibits and the presentation.

The Wisconsin Department of Transportation (WisDOT) recognizes that businesses located in work zones are faced with unique challenges. It’s critical that customers, employees and delivery vehicles have access to businesses, regardless of any roadwork inconvenience.
