Until the bridge was completed in 1957, travel between the two peninsulas was difficult and slow (and sometimes even impossible during winter). In 1881, the Mackinac Transportation Company was established by three railroads, the Michigan Central Railroad, the Grand Rapids and Indiana Railroad, and the Detroit, Mackinac and Marquette Railroad, to operate a railroad car ferry across the Straits. Beginning in 1923, the State of Michigan operated automobile ferries between the two peninsulas. At the busiest times of year the wait was several hours long, much longer at holidays. In winter, travel was possible over the ice only after the straits had solidly frozen. Highways There are one Interstate Highway, five US Highways and 24 other state highways in the Upper Peninsula. Interstate 75 is the only freeway in the region and runs from the Mackinac Bridge at St. Ignace to the International Bridge at Sault Ste. Marie. Two highways run the east–west length of the peninsula, US Highway 2 along the south and M-28 to the north. US 41 runs north–south through the central and western UP, connecting Menominee, Escanaba, Marquette and Houghton before terminating near the tip of the Keweenaw at Copper Harbor. M-185 encircles Mackinac Island as the only state highway in the country without motor vehicles. The United States Forest Service and Federal Highway Administration have designated certain roads within the several National Forests in the UP as Federal Forest Highways. State-maintained highways closest to the Upper Peninsula's Great Lakes shorelines are marked by the Michigan Department of Transportation (MDOT) with signs indicating that they are part of the Great Lakes Circle Tour, a designated scenic road system connecting all of the Great Lakes and the St. Lawrence River. MDOT has also designated five UP highways as Pure Michigan Byways for their historic, recreational or scenic qualities. They are: US
