USH 41 Freeway Modernization
Client: Wisconsin Department of Transportation
Location: Washington County, Wisconsin
This project consisted of reconstructing the US 41 / WIS 144 interchange. The project included updating a former plan to meet current design standards, including changing the entrance and exit ramp geometrics to parallel ramp design standards.
Donohue also provided the design to reconstruct one mile of WIS 144 as an urban roadway. Intersections were redesigned to provide an exclusive left turn lane to Overlook Drive. As Wisconsin DOT designed the US 41 bridge, Donohue incorporated their efforts into the updated environmental report and project construction documents.
The redesigned the storm sewer and guardrails associated with this roadway section were included in the plan. Existing shoulders between the ramp gores were removed and replaced according to current design standards.
The construction cost for the entire project was $8.5 million.
