The County-Designated Highways in Michigan comprise a 1,241.6 mi system of primary county roads across the US state of Michigan.
 Unlike the State Trunkline Highway System, these highways have alphanumeric designations with letters that correspond to one of six lettered zones in the state.
 The CDH system was created in 1970 in response to the business concerns of a woman from Saugatuck.
 Her one-woman crusade in the 1960s started after the highway in front of her motel was turned over to local control as a county road and removed from state highway maps when the nearby freeway opened.
 After nearly a decade of efforts, the first two test highways were designated, one each in the Lower and Upper peninsulas of the state and included on the 1970 state highway map.
 The CDH system was created and expanded in scope  October 5, 1970 , after it was approved by the County Road Association of Michigan and the State Highway Commission.
The Peninsulas of Michigan are a pair of fresh water peninsulas defined by several components of the Great Lakes and their connecting waterways which together compose the U.S. state of Michigan.
 The Upper Peninsula to the north has a more rural and jagged landscape than the more urban and level Lower Peninsula to the south.
 Separating the two parts are the Straits of Mackinac which joins Lake Michigan to Lake Huron at an even flow.
 Persons crossing between the two landmasses had to use ferries in sometimes ice-prone conditions until the construction of the Mackinac Bridge.
 Long tracts of shore along both peninsulas with several Great Lakes give Michigan the largest territorial waters of any state except Alaska (which has thousands of miles of coast).
 The Lower Peninsula has a population that is well over an order of magnitude larger than that of the Upper Peninsula due to the presence of big cities including Detroit and Grand Rapids with histories of substantial manufacturing and technology employment.
 The cultural differences between the Michigan peninsulas tend to have greater meaning to residents of the Upper Peninsula than to those of the Lower Peninsula due to their reliance on forestry and mining which puts them at variance both economically and politically with the rest of the state.
M-185 is a state trunkline highway in the U.S. state of Michigan that circles Mackinac Island, a popular tourist destination on the Lake Huron side of the Straits of Mackinac, along the island's shoreline.
 A narrow paved road of 8.004 mi , it offers scenic views of the straits that divide the Upper and the Lower peninsulas of Michigan and Lakes Huron and Michigan.
 It has no connection to any other Michigan state trunkline highways—as it is on an island—and is accessible only by passenger ferry.
 The City of Mackinac Island, which shares jurisdiction over the island with the Mackinac Island State Park Commission (MISPC), calls the highway Main Street within the built-up area on the island's southeast quadrant, and Lake Shore Road elsewhere.
 M-185 passes by several important sites within Mackinac Island State Park, including Fort Mackinac, Arch Rock, British Landing, and Devil's Kitchen.
 Lake Shore Road carries the highway next to the Lake Huron shoreline, running between the water's edge and woodlands outside the downtown area.
The following is a list comprising the fifty tallest skyscrapers in the U.S. state of Michigan.
 Skyscrapers are listed in descending order, from first to fiftieth.
 This tallest fifty includes completed, existing, free-standing skyscrapers.
 Height does not take into account subterranean floors, antennas, or other non-structural additions.
 There is also a timeline of the tallest buildings in Michigan and a timeline of the tallest skyscrapers.
 The Renaissance Center in Detroit, Michigan contains the tallest all-hotel skyscraper in the Western Hemisphere.
Interstate 75 (I-75) is a part of the Interstate Highway System that runs from Miami, Florida, to Sault Ste. Marie in the Upper Peninsula of Michigan.
 I-75 enters Michigan 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 mi on both of Michigan's 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 (BL I-75) or Business Spur I-75 (BS I-75) designations.
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 65.260 mi in rural UP forest lands.
The State Trunkline Highway System consists of all the state highways in Michigan, including those designated as Interstate, United States Numbered (US Highways), or State Trunkline highways.
 In their abbreviated format, these classifications are applied to highway numbers with an "I"-, "US", or "M"- prefix, respectively.
 The system is maintained by the Michigan Department of Transportation (MDOT) and comprises 9,669 mi of trunklines in all 83 counties of the state on both the Upper and Lower peninsulas (UP, LP), which are linked by the Mackinac Bridge.
 Components of the system range in scale from 10-lane urban freeways with local-express lanes to two-lane rural undivided highways to a non-motorized highway on Mackinac Island where cars are forbidden.
 The longest highway is nearly 400 mi long, while the shortest is about three-quarters of a mile (about 1.2 km).
 Some roads are unsigned highways, lacking signage to indicate their maintenance by MDOT; these may be remnants of highways that are still under state control whose designations were decommissioned or roadway segments left over from realignment projects.
The Upper Peninsula is the northern of the two major peninsulas that make up the U.S. state of Michigan.
 It may also be referred to as the UP or Upper Michigan.
 The peninsula is bounded on the north by Lake Superior, on the east by the St. Marys River, on the southeast by Lake Michigan and Lake Huron, and on the southwest by Wisconsin.
A Pure Michigan Byway is the designation for a segment of the State Trunkline Highway System in the US state of Michigan that is a "scenic, recreational, or historic route that is representative of Michigan's natural and cultural heritage."
 The designation was created with the name Michigan Heritage Route by the state legislature on June 22, 1993, and since then five historic, seven recreational and six scenic byways have been designated by the Michigan Department of Transportation (MDOT), and another two have been proposed.
 These byways have been designated in both the Upper and Lower peninsulas (UP, LP) of the state.
 The current name was adopted on December 30, 2014, and it references the Pure Michigan tourism marketing campaign.
Due to its unique geography, being made of two peninsulas surrounded by the Great Lakes, Michigan has depended on many ferries for connections to transport people, vehicles and trade.
 The most famous modern ferries are those which carry people and goods across the Straits of Mackinac to the car-free Mackinac Island but before the Mackinac Bridge was built, large numbers of ferries carried people and cars between the two peninsulas.
 Other ferries continue to provide transportation to small islands and across the Detroit River to Canada.
 Ferries once provided transport to island parks for city dwellers.
 The state's only national park, Isle Royale cannot be reached by road and is normally accessed by ferry.
 The largest ferries in Michigan are the car ferries which cross Lake Michigan to Wisconsin.
 One of these, the SS "Badger" is one of the last remaining coal steamers on the Great Lakes and serves as a section of US Highway 10 (US 10).
 The "Badger" is also the largest ferry in Michigan, capable of carrying 600 passengers and 180 autos.

Question: Which of the two major peninsulas that make up the state of Michigan contains the M-69 Highway?
Answer: The Upper Peninsula
