The 2019 Construction Guide for the I-39/90 Expansion Project is now available on the project website.

Learn the locations of this year’s I-39/90 construction work and download the 2019 Construction Guide. It will also be available in print at the Wisconsin DOT Project Field Office in Edgerton, visitor centers, rest areas, Division of Motor Vehicle (DMV) locations, area libraries, local government buildings, gas stations, and hotels adjacent to the Interstate.

The Guide highlights this year’s construction projects, and identifies alternate routes used during and after the Interstate expansion for congestion and incident management. There are also useful tips for driving in work zones, as well as an overview of the entire project.
