US 41 is under heavy construction during the summer of 1999 between CTH J and CTH F (Scheuering Rd), just south of DePere. WisDOT is constructing two new interchanges at CTH U and CTH S, replacing congested and dangerous intersections. This is part of a 2-year project that will convert US 41 from an expressway to a freeway between Appleton and Green Bay.
