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 , it crosses into Michigan for approximately another . After that, it crosses back into Wisconsin for about before crossing the state line one last time. The northernmost Michigan section is about , making the overall length about . 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 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. ==Route description== As a bi-state highway, US 141 is a state trunk highway in Wisconsin and a state trunkline highway in Michigan. In Wisconsin, the segment through the Green Bay area is not on the National Highway System (NHS), except for about four blocks along Broadway Avenue that is part of an intermodal connector with the Port of Green Bay. The NHS is a network of roads important to the country's economy, defense, and mobility. From the Green Bay suburb of Howard northward, including the entire length through Michigan, US 141 is a part of the NHS. From the I-43 interchange in Howard north to the split at Abrams, US 141 is also a part of the Lake Michigan Circle Tour (LMCT), a tourist route that surrounds Lake Michigan.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「U.S. Route 141」の詳細全文を読む スポンサード リンク
