STH 141 (WI)

US Highway 141 (US 141) is a north–south United States Numbered Highway in the US states of Wisconsin and Michigan. The highway runs from an interchange with Interstate 43 (I-43) in Bellevue, Wisconsin, near Green Bay to a junction with US 41/M-28 near Covington, Michigan. In between, it follows city streets in Green Bay and has a concurrent section with US 41 in Wisconsin. North of Green Bay, sections are either freeway or expressway into rural northern Wisconsin. In Michigan, US 141 is an undivided highway that runs through rural woodlands. The highway has two segments in each state; after running through Wisconsin for about 102 miles (164 km), it crosses into Michigan for another eight miles (13 km). After that, it crosses back into Wisconsin for about 14.5 miles (23.3 km) before crossing the state line one last time. The last Michigan section is about 44 miles (71 km), making the overall length 168.82 miles (271.69 km).

When the US Highway System was formed on November 11, 1926, US 141 ran from Milwaukee to Green Bay, and one segment of the modern highway in Michigan was originally designated US 102. This other designation was decommissioned in 1928 when US 141 was extended north from Green Bay into Michigan. Michigan has rebuilt the highway in stages over the years to smooth out sharp curves in the routing. Since the 1960s, the section south of Green Bay was converted into a freeway in segments. This freeway is now I-43, and since the 1980s, US 141 has ended southeast of Green Bay in Bellevue. The section north of Abrams, Wisconsin, was converted to a freeway in the opening years of the 21st century with an additional divided-highway section opening a few years later.
