The Lake Butte des Morts Crossing project consisted of 9 bridge structures, 4 MSE retaining walls, extensive grading and mainline paving including 4 round-a-bouts.
USH 41 is a major transportation artery serving northern Wisconsin which required phased demolition and construction of the bridge structures over the Lake Butte des Morts Causeway to keep traffic flowing. The signature structures on the project were two 6 span pre-stressed girder bridges, which replaced two 9 span steel girder bridges. There was large focus on the aesthetic details stemming from the community outreach done during the design phase which included having each of the 5 piers represented by a different meaningful symbol. Overall, the three sets of bridges over the causeway each represented a specific natural element; earth, water, fire.
