M-72 was first designated as a state highway by 1919 along a segment of its current route. It was extended southward in the mid 1920s and westward in the 1940s. One section of the modern highway added to M-72 in 1940 previously existed as M-208 in the 1930s east of Grayling. Another section of highway near Empire was disconnected from the rest of M-72 until the gap was eliminated later in the decade. All of M-72 was completely paved by the early 1960s. The highway was rerouted in a few places in the 1950s, and the last new segment shifted in 1973 near Kalkaska

As a part of its maintenance duties, the department tracks the traffic volumes along its roads using a metric called average annual daily traffic (AADT).

In 2009, the MDOT surveys found that the highest traffic levels along M-72 were the 33,720 vehicles per day in Traverse City. The lowest AADT was 807 vehicles near Hubbard Lake Road in Alcona County near Lincoln. Commercial traffic varied between the 555 trucks a day in Graylling and the 72 trucks daily west of Harrisville.

 in 1940. From there M-72 was extended further to just south of Kalkaska along a section of highway previously designated M-76
M-76 (Michigan highway)
M-76 is a former state trunkline highway designation in the Lower Peninsula of the US state of Michigan. The highway's designation was decommissioned when the last section of it was converted to freeway as a part of the present-day Interstate 75 . At that time, M-76 extended from US Highway 23 ...

. A seven-mile (11 km) long discontinuous segment of highway some 45 miles (72.4 km) west of Kalkaska near Empire was also redesignated as part of M-72. The section of highway south to Roscommon became M-144. By 1945, the western segment was extended east into Traverse City. The two segments were joined when M-72 was routed along US 31 through Traverse City to Acme by early 1948. From there, M-72 was routed along existing roads through Williamsburg to US 131/M-66 north of Kalkaska where it followed the latter highways through downtown to bridge the gap. With this addition to the routing, the road extended "shore to shore" from Lake Huron to Lake Michigan.

The Michigan State Highway Department rerouted M-33/M-72 near Fairview in late 1951 or early 1952, turning the former route back to local control. In the middle of 1953, the section of M-65/M-72 in Alcona County was straightened and paved. All but the western three miles (4.8 km) of the earthen highway section opened in 1940 were paved in 1957. By the middle of 1961, the highway would be paved in its entirety. A new section of highway was opened in 1973, rerouting M-66 and M-72 due west from their junction to US 131, bypassing a former routing north into Kalkaska.

 in the 1930s. The highway was designated by 1936, and it was removed from the highway system in 1939. By the end of 1940, the roadway was redesignated as a part of the state highway system when M-72 was extended to the bridge from the east and then over the former M-208 to Grayling. The roadway has remained a state highway since.
