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).
U.S. Highway 8 (US 8) is a United States Numbered Highway that runs primarily east–west for 280 miles (451 km), mostly within the state of Wisconsin. It connects Interstate 35 (I-35) in Forest Lake, Minnesota, to US 2 at Norway in the Upper Peninsula of Michigan near the border with Wisconsin. Except for the short freeway segment near Forest Lake, a section near the St. Croix River bridge, the interchange with US 51, and a three-mile (4.8 km) stretch west of Rhinelander, Wisconsin, it is mostly an undivided surface road. As a state highway in the three states, US 8 is maintained by the Minnesota, Wisconsin and Michigan departments of transportation.
State Trunk Highway 157 is a short state highway in the US state of Wisconsin. It runs east on Main Street from WIS 35 in downtown Onalaska to the US Highway 53 (US 53) freeway. There it turns south, running concurrently with US 53 to the Interstate 90 (I-90) interchange. US 53 leaves WIS 157 to head west on I-90, but WIS 157 continues southeast to WIS 16 at the Valley View Mall.
State Trunk Highway 39 is a state highway in the U.S. state of Wisconsin. It runs in east–west across south central Wisconsin from Edmund to New Glarus.
State Trunk Highway 62 was a state highway in the U.S. state of Wisconsin. Its latest routing ran north–south on South Packard and Kinnickinnic avenues within the cities of Cudahy, St. Francis, and Milwaukee. Maintenance was turned back to the cities in 1999, and signs were removed, after the completion of the Lake Parkway (WIS 794).
State Trunk Highway 86 is a state highway in the U.S. state of Wisconsin. It runs east–west in north central Wisconsin from Ogema to Tomahawk.
State Trunk Highway 89 is a 72-mile (116 km) state highway in the southeastern part of the U.S. state of Wisconsin. It travels south to north from near Delavan to Columbus.
State Trunk Highway 91 is a state highway in the U.S. state of Wisconsin. It runs east–west in east-central Wisconsin from near Berlin to Oshkosh.
State Trunk Highway 138 is a state highway in the U.S. state of Wisconsin. It runs west–east between Oregon and Stoughton and north–south between Stoughton and Cooksville.
State Trunk Highway 140 is an 11.50-mile (18.51 km) state highway in Rock County, Wisconsin, United States, that runs in north–south from the Illinois border, near Bergen, through Clinton to east of Emerald Grove. The highway was designated in 1923/1924 and paved in the early 1930s.
State Trunk Highway 150 was a state highway in the U.S. state of Wisconsin. It ran east–west between Winchester and Neenah. In 2003, the road was turned over to Winnebago County, which now maintains it as County Trunk Highway II (CTH-II).
State Trunk Highway 168 was a state highway in the U.S. state of Wisconsin. It ran east–west for 5.93 miles (9.54 km) between Nichols and Seymour. Because it paralleled WIS 54 and WIS 156, the road was turned over to Outagamie County control in 2003, and is now designated as County Trunk Highway VV (CTH-VV).
State Trunk Highway 178 is a 23.3-mile (37.5 km) state highway in Chippewa County, Wisconsin, United States, that runs north–south roughly along the Chippewa River from Chippewa Falls to Cornell.
M-41 was the designation of a former state trunkline highway in the Lower Peninsula of the US state of Michigan that began near Holton and ran north- and northwest-ward, ending at Hart. The highway was created by 1919 and lasted until 1926. The designation has not been reused since.
At least 14 special routes of U.S. Route 14 (US 14) have existed.
A total of three business routes of U.S. Highway 12 (US 12) currently exist in Wisconsin. Business routes typically run through cities, after a highway was realigned. None are official state highways according to the Wisconsin Department of Transportation (WisDOT) and are thus locally maintained.
A total of three business routes of U.S. Route 41 exist in Wisconsin. Additionally, there were four business routes that have since been disestablished. Business routes typically run through cities, after a highway was realigned. None are official state highways according to the Wisconsin Department of Transportation (WisDOT) and are thus locally maintained, with the exception of the route through De Pere and Ashwaubenon.
State Trunk Highway 135 (WIS 135) was a state highway in the U.S. state of Wisconsin. At its latest routing, it traveled from WIS 59 in Palmyra to WIS 106 near Hebron.
State Trunk Highway 148 was a state highway in Manitowoc County, Wisconsin. It ran from US Highway 151 (US 151) and County Trunk Highway J (CTH-J) in Valders to US 10 in Cato.
Several special routes exist for U.S. Route 51.
