Michigan highway system

Encyclopedia : M : MI : MIC : Michigan highway system

This is a map of highways in the state of Michigan, however not all highways are in the map, nor are they all totally accurate.

This lists all roads designated as Interstates, U.S. Highways and State Highways in Michigan.

State Highways

Note that in Michigan, all state highways (not Interstates and U.S. highways) are identified as "M-nn" as opposed to "Route nn" or "Highway nn." This usage dates from 1918, when Michigan's state trunklines were first signed in the field. The state highway route marker is a diamond with a block letter "M" at the top.

Although "M-nn" outside of Michigan could refer to other state, provincial, local, or national highways, local usage in those areas does not mimic the Michigan usage in most cases. In the United Kingdom, "M" refers to motorways, analogous to freeways in the United States. The "M" in the "M-nn" route designation never refers to "superhighway" or "freeway" status in Michigan, however. "M-routes" (Michigan state trunklines) are designated along eight-lane freeways in urban aras, four-lane rural freeways and expressways, principal arterial highways, lonely two-lane highways in far-flung rural areas, and even a pedestrian trial restricted to bicycle and non-motorized transportation with the exception of emergency vehicles.

No discernible pattern is to be inferred in Michigan's numbering system.

History

While Michigan was the second jurisdiction to post route designations along its state trunkline highway system in 1919—neighboring Wisconsin was the first a year earlier in 1918—it actually began assigning internal trunkline route designations for internal inventory purposes as early as 1913. From 1918 to 1926, only the "M-numbered" route designations existed on state highways throughout Michigan, while the coming of the U.S. Highway System in 1926 caused several existing designations to be either reassigned or retired altogether. All single-digit state trunkline designations (e.g. M-9) were removed from the system in the late-1930s, purportedly reserved for a proposed "Superhighway" system in early planning stages at the time, never built due to the coming of World War II. (The Michigan Department of Transportation began reassigning single-digit route designations in the 1970s on mostly urban trunklines.) While Michigan has long allowed route designation duplication between the traditional state routes and U.S. Highways, the coming of the Interstate Highway System in the late-1950s further illustrated this with each mainline Interstate designation having a similar (but unrelated) "M-numbered" state route designation elswhere in the state. However, many U.S. Highways in Michigan have left an M-numbered highway with the same route number as a relic of their existance (e.g. M-27 runs along a portion of former US-27). In addition, two occurrences of an original "M-numbered" state route which became U.S. Highways with the same route designation existed: all of M-16 became US-16 (originally planned to be designated US-18) and most of M-10 from Detroit to Saginaw was assumed into the route of US-10 in 1926 (each iteration of M-10 has existed along a former or future alignment of US-10, at least in part).
