I-90/39 Construction Information

Project Overview
Construction on the Rock River bridge and along I-90/I39 near Edgerton has begun and will continue until Summer 2018 according to WI DOT’s schedule.  We’ve prepared this page to make it easy for you to find all the resources about the construction in one place.

Boater Awareness

During construction, the northbound and southbound bridges crossing the Rock River will be replaced. Please be alert for construction crews and work taking place in the river. Navigational buoys have been placed in the river to guide boaters through the construction zone. This area is no wake and boaters are asked to take extra caution when navigating this area. Periodically, the buoys will be relocated in the river as construction progresses.
