 Grading for the old alignment is still visible to the southwest of the current WIS 23/I-43 interchange, and the rest of the old alignment is still in use today as Greenfield Drive.Proposals were considered that would have rerouted WIS 23 around Lake Delton by following CTH H from Reedsburg directly to Wisconsin Dells, but the village of Lake Delton did not support the plan due to pressure from local businesses.WisDOT had made Wisconsin 23 between Fond du Lac and Sheboygan a priority state corridor in its highway planning, studying the expansion of WIS 23 from Fond du Lac to Plymouth to a four-lane expressway, as the rural two-lane portion between Mount Calvary and Greenbush towards the county line, along with the two-lane narrowing just outside of Fond du Lac, has been the site of a number of various accidents with casualties.
