Lunda’s scope of work includes constructing the interchange's two signature flyover structures: a 21-span, 3,182-foot-long bridge and a 9-span, 1,072-foot-long bridge. Both structures will pair prestressed concrete girders in the approach spans with 72-inch steel plate girders over the I-41 mainline and ramp crossings — work that aligns squarely within Lunda's core structural competency. The package also includes associated interchange retaining walls, the widening and deck replacement of Wisconsin State Highway 441 over County Highway OO, and the removal of the existing interchange structures over Highway I-41.
