a strategic effort was made along US 41 to convert the remaining expressway segments between Richfield and Abrams to freeway. The freeway conversion, which was completed by 2001, cleared the way for Interstate 41 to be designated along the corridor from the Illinois state line to Green Bay. Additionally, in the 2000s, the highway was upgraded to an expressway from Abrams to just west of Marinette, and included freeway bypasses around the cities of Oconto and Peshtigo.
