US Highway 141 (US 141) is a north–south United States Numbered Highway in the states of Wisconsin and Michigan. The highway runs north-northwesterly 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, US 141 is either a freeway or an expressway into rural northern Wisconsin before downgrading to an undivided highway. 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 103 miles (166 km), it crosses into Michigan for approximately another eight miles (13 km). After that, it crosses back into Wisconsin for about 14+1⁄2 miles (23 km) before crossing the state line one last time. The northernmost Michigan section is about 43+1⁄2 miles (70 km), making the overall length about 169 miles (272 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 Highway 102 (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 has been converted into a freeway in segments. US 141 has ended southeast of Green Bay in Bellevue since the 1980s—the southern freeway segment was redesignated as I-43. 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.
