Мичиган М-11 тас жолының тарихы мен сипаттамасы

State highway in Ottawa and Kent counties in Michigan, United States
M 11 is maintained by the Michigan Department of Transportation (MDOT) like other state highways in Michigan. As a part of these maintenance responsibilities, the department tracks the volume of traffic that uses the roadways under its jurisdiction. These volumes are expressed using a metric called annual average daily traffic, which is a statistical calculation of the average daily number of vehicles on a segment of roadway. MDOT's surveys in 2010 showed that the highest traffic levels along M 11 were the 41,214 vehicles daily between Kalamazoo and Breton avenues in Grand Rapids; the lowest counts were the 8,153 vehicles per day in Ottawa County. All of M 11 has been listed on the National Highway System, a network of roads important to the country's economy, defense, and mobility.

The first M 11 originally ran along Lake Michigan between the Indiana state line near New Buffalo and Mackinaw City on July 1, 1919. On November 11, 1926, the New Buffalo–Benton Harbor segment was used for US 12 and the Watervliet–Mackinaw City section was used for US 31; between Benton Harbor and Watervliet, M 11 was used for a concurrent US 12/US 31. Streets are still designated as Old M 11 in places such as Chikaming Township. Immediately after the debut of the U. S. Highway System in 1926, M 11 was designated from M 50 at Napoleon to US 112 in Saline. The last section of this highway was fully paved between Bridgewater and Saline in late 1948 or early 1949. In the middle of 1954, M 92 was extended southward from Chelsea to Manchester. From there, that highway replaced M 11 west to Bridgewater before turning south to Clinton; at the same time, the remainder of M 11 was removed from the state highway system and the designation was decommissioned.

The current M 11 was known as Beales Road in the early 1900s and was a sandy road placed over hills where it ended just west of Byron Center Avenue at gravel pits. The modern highway was added to the state highway system as a component of M 114 c. 1930. By 1942, the trunkline was completed and reassigned a Bypass US 16 designation, until the mainline US 16 was rerouted over the bypass in 1953. In the latter half of 1961, the M 11 designation was first assigned in the Grand Rapids area along the current routing when US 16 was moved to the newly opened I 96 freeway. The routing has remained unchanged since.
