M-18 is a north–south
When the highway was first designated in the late 1910s, it extended farther south than it does today and ended well short of its current northern terminus. The southern end was added to another state highway, truncating M-18's length to roughly its current southern terminus in 1926. The northern end was also simultaneously extended for the first time with these revisions to the highway's routing. In the 1940s, the northern extension was reversed and then reinstated. M-18's course was last changed with the opening of three different freeways in the area in the 1960s and 1970s. The last extension in 1973 supplanted the M-144 designation from Roscommon north to Luzerne.
Route description
M-18 begins about 20 miles (32 km) northeast of
The highway turns westward along Wirtz Road and past the southern terminus of county road
North of this freeway interchange, M-18 is also the route of
M-18 is maintained by the Michigan Department of Transportation (MDOT) like all other state trunkline highways. As a part of these maintenance responsibilities, the department tracks the traffic volumes along the roads under its jurisdiction using a measurement called annual average daily traffic (AADT). This is a metric for the level of traffic along a roadway segment for any average day of the year. In 2009, MDOT calculated that 14,017 vehicles used the section of M-18 along the M-61 concurrency, the highest traffic levels along M-18. The lowest AADT was found along the highway in Crawford County in the 2009 surveys. Commercial traffic varied between the 50 trucks daily in Crawford County and the 214 trucks a day north of Gladwin.[8] No section of M-18 has been listed on the National Highway System,[9] a network of roads important to the country's economy, defense, and mobility.[10]
History
By July 1, 1919, M-18 was first designated on a routing that ran between M-46 west of Merrill through Edenville to M-14 (later US 27) in Prudenville.[2] The highway south of Beaverton was realigned to run due south a new terminus at North Bradley along the new US 10 in late 1926. The former routing between Beaverton and M-30 north of Edenville was redesignated M-80, and the highway from the M-30 junction south to M-46 became an extended M-30. At the same time, the north end was extended along US 27 to end at M-76 in Roscommon.[11] The northern extension was scaled back in 1941 to Prudenville.[12][13]
