The Upper Peninsulaof Michigan – also known as Upper Michigan or colloquially the U.P. – is the northern and more elevated of the two major landmasses that make up the U.S. state of Michigan; it is separated from the Lower Peninsula by the Straits of Mackinac. It is bounded primarily by Lake Superior to the north, separated from the Canadian province of Ontario at the east end by the St. Marys River, and flanked by Lake Huron and Lake Michigan along much of its south. Although the peninsula extends as a geographic feature into the state of Wisconsin, the state boundary follows the Montreal and Menominee rivers and a line connecting them.
U.S. Route 2 or U.S. Highway 2 (US 2) is an east–west U.S. Highway spanning 2,571 miles (4,138 km) across the northern continental United States. US 2 consists of two segments connected by various roadways in southern Canada. Unlike some routes, which are disconnected into segments because of encroaching Interstate Highways, the two portions of US 2 were designed to be separate in the original 1926 highway plan.
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).
M-25 is a state trunkline highway in the US state of Michigan. The route follows an arc-like shape closely along the Lake Huron shore of the Thumb in the eastern Lower Peninsula between Port Huron and Bay City. It serves the lakeshore resorts along Lake Huron and Saginaw Bay and generally lies within sight of the lake and the bay. All is surface road and generally scenic, except for the freeway segment near the junction with Interstate 75 (I-75) and connection into the US Highway 10 (US 10) freeway.
M-28 is an east–west state trunkline highway that traverses nearly all of the Upper Peninsula of the U.S. state of Michigan, from Wakefield to near Sault Ste. Marie in Bruce Township. Along with US Highway 2 (US 2), M-28 forms a pair of primary highways linking the Upper Peninsula from end to end, providing a major access route for traffic from Michigan and Canada along the southern shore of Lake Superior. M-28 is the longest state trunkline in Michigan numbered with the "M-" prefix at 290.373 miles (467.310 km). The entire highway is listed on the National Highway System, while three sections of M-28 are part of the Lake Superior Circle Tour. M-28 also carries two memorial highway designations along its route.
H-63 is a county-designated highway (CDH) in the Upper Peninsula of the US state of Michigan. The highway parallels the Interstate 75 (I-75) corridor between St. Ignace and Sault Ste. Marie. The road is called Mackinac Trail after the Upper Peninsula branch of an Indian trail used before European settlers reached the area. Originally, the roadway was built as a section of US Highway 2 (US 2) before being added to the CDH system in the 1970s.
The Sault Ste. Marie Tribe of Chippewa Indians, commonly shortened to Sault Tribe of Chippewa Indians or the more colloquial Soo Tribe, is a federally recognized Native American tribe in what is now known as Michigan's Upper Peninsula. The tribal headquarters is located within Sault Ste. Marie, the major city in the region, which is located on the St. Marys River.
M-129 is a state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It runs from Cedarville to Sault Ste. Marie. South of Nine Mile Road in Chippewa County, M-129 overlays the Michigan Meridian. The section of M-129 that overlays the meridian is named Meridian Road. The highway between M-48 and the northern terminus is a part of the larger Lake Huron Circle Tour.
M-45 is a state trunkline highway in the US state of Michigan that is also called Lake Michigan Drive. The highway runs from Agnew near Lake Michigan to the west side of Grand Rapids in the western Lower Peninsula. Lake Michigan Drive continues in each direction from M-45's termini, extending west of US Highway 31 (US 31) and east of Interstate 196 (I-196). In between, the road runs through rural and suburban areas of Ottawa and Kent counties, including the main campus of Grand Valley State University in Allendale. Lake Michigan Drive was originally part of M-50 until the mid-1960s. Previously in the 1920s and 1930s, the M-45 number was designated along a highway in the Upper Peninsula (UP).
US Highway 27 (US 27) is a part of the US Highway System that now runs from Miami, Florida, to Fort Wayne, Indiana. In the US state of Michigan, it was a north–south state trunkline highway that entered the state south of Kinderhook and ended south of Grayling. Its route consisted of a freeway concurrency with Interstate 69 (I-69) from the state line north to the Lansing area before it followed its own freeway facility northward to St. Johns. From there north to Ithaca, US 27 was an expressway before continuing as a freeway to a terminus south of Grayling.
M-134 is an east–west state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It connects Interstate 75 (I-75) north of St. Ignace with the communities of Hessel, Cedarville and De Tour Village along Lake Huron. East of De Tour, the highway crosses the De Tour Passage on a ferry to run south of the community of Drummond on Drummond Island. It is one of only three state trunklines in Michigan on islands; the others are M-154 on Harsens Island and M-185 on Mackinac Island. M-134 is also one of only two highways to utilize a ferry in Michigan; the other is US Highway 10 (US 10) which crosses Lake Michigan from Manitowoc, Wisconsin, to Ludington. Most of the mainland portion of M-134 is also part of the Lake Huron Circle Tour, and since 2015, it has been a Pure Michigan Byway under the name M-134 North Huron Byway.
M-123 is a state trunkline highway in the eastern Upper Peninsula of the U.S. state of Michigan. It is one of only a few highways in Michigan that curve around and form a U-shape. In fact, M-123 has three intersections with only two state trunklines; it meets M-28 twice as a result of its U-shaped routing. M-123 also has a rare signed concurrency with a County-Designated Highway in Michigan; in Trout Lake, there is a concurrency with H-40. All of M-123 north of M-28 is a Scenic Heritage Route within the Michigan Heritage Route system.
Interstate 75 (I-75) is a part of the Interstate Highway System that runs north–south from Miami, Florida, to Sault Ste. Marie in the Upper Peninsula of the US state of Michigan. I-75 enters the state from Ohio in the south, north of Toledo, and runs generally northward through Detroit, Pontiac and Bay City, crosses the Mackinac Bridge, and ends at the Canadian border in Sault Ste. Marie. The freeway runs for approximately 396 miles (637 km) on both of Michigan's major peninsulas. The landscapes traversed by I-75 include Southern Michigan farmland, northern forests, suburban bedroom communities, and the urban core of Detroit. The freeway also uses three of the state's monumental bridges to cross major bodies of water. There are four auxiliary Interstates in the state related to I-75, as well as nine current or former business routes, with either Business Loop I-75 or Business Spur I-75 designations.
M-95, designated the Leif Erickson Memorial Highway, is a state trunkline highway in the Upper Peninsula of the US state of Michigan. Running from Kingsford to near Champion in Humboldt Township, it is the main connection between Iron Mountain and Marquette along with US 41.
M-69 is an east–west state trunkline highway in the Upper Peninsula (UP) of the U.S. state of Michigan. It connects with US Highway 2 (US 2) on both ends in Crystal Falls and near Bark River. In between, the highway runs for 65.26 miles (105.03 km) in rural UP forest lands.
M-83 is a north–south state trunkline highway in the Lower Peninsula of the US state of Michigan primarily serving as a link between Interstate 75/US Highway 23 (I-75/US 23) in Birch Run, including a short east–west section with M-54, and the Bavarian-themed town of Frankenmuth. M-83 is primarily a north–south trunkline that passes by such landmarks as Bronner's Christmas Wonderland, Zehnder's and the Bavarian Inn before leaving town. The landscape in the remainder of the area is composed of farm fields between Frankenmuth and the northern terminus at M-15 near Richville.
There have been nine business routes for Interstate 75 in the US state of Michigan. Numbered either Business Loop Interstate 75 or Business Spur Interstate 75 depending if they are a full business loop or a business spur, these highways are former routings of I-75's predecessor highways in the state. They were designated as I-75 was completed through the various areas of Michigan. The business loop in Pontiac runs through that city's downtown along a section of Woodward Avenue and a segment of roadway formerly used by M-24. The former Saginaw business loop was once a part of US Highway 23 (US 23), as was most of the original Bay City business loop. The roadways that make up the business loops in West Branch and Roscommon were previously part of M-76, I-75's predecessor through that part of the state. In Northern Michigan, the Grayling and Gaylord BL I-75s were part of US 27, and the two business routes in St. Ignace and Sault Ste. Marie in the Upper Peninsula of Michigan were part of US 2. A tenth business route, a loop through Indian River has been proposed. Each of the business loops connects to I-75 on both ends and runs through their respective cities' downtown areas. The two business spurs only connect to I-75 on one end and run into the appropriate downtown.
Business M-28 was a state trunkline highway in the Upper Peninsula of Michigan. It served as a business route running for 9.010 miles (14.500 km) through the Newberry area. The business loop followed a U-shaped routing to connect downtown Newberry with M-28 south of town. It ran west of the city of Newberry, passing through the community of Dollarville before entering downtown, turning south and ending near the county airport.
US Highway 2 (US 2) is a component of the United States Numbered Highway System that connects Everett, Washington, to the Upper Peninsula (UP) of the US state of Michigan, with a separate segment that runs from Rouses Point, New York, to Houlton, Maine. In Michigan, the highway runs through the UP in two segments as a part of the state trunkline highway system, entering the state at Ironwood and ending at St. Ignace; in between, US 2 briefly traverses the state of Wisconsin. As one of the major transportation arteries in the UP, US 2 is a major conduit for traffic through the state and neighboring northern Midwest states. Two sections of the roadway are included as part of the Great Lakes Circle Tours, and other segments are listed as state-designated Pure Michigan Byways. There are several memorial highway designations and historic bridges along US 2 that date to the 1910s and 1920s. The highway runs through rural sections of the UP, passing through two national and two state forests in the process.
The Great Lakes Circle Tour is a designated scenic road system connecting all of the Great Lakes and the St. Lawrence River. It consists of routes for circumnavigating the lakes, either individually or collectively.
