The US Highways in Michigan are the segments of the national

United States Numbered Highway System[4] that are owned and maintained by the state of Michigan,[5] totaling 2,300 miles (3,701 km).[3] The longest of these is US Highway 23 (US 23) at around 362 miles (583 km). On a national level, the standards and numbering for the system are handled by the American Association of State Highway and Transportation Officials (AASHTO), while the highways in Michigan are maintained by the Michigan Department of Transportation
(MDOT).

The original highways were approved on November 11, 1926, by AASHTO including 14 mainline highways. A handful of these original highway designations no longer run within Michigan, and a few numbers have been added since the 1930s. Since 1999, there have been 13 mainline highways, and with the creation of a

Interstate Highways
and no longer part of the US Highway System. These freeway conversions started in the 1940s and 1950s and continued through to the turn of the 21st century.

Description

MDOT is the agency responsible for the day-to-day maintenance and operations of the State Trunkline Highway System, which includes the U.S. Highways in Michigan. The numbering for these highways is coordinated through AASHTO,[6] an organization composed of the various state departments of transportation in the United States.[7] Under the scheme finalized in 1926, two-digit US Highways are numbered in a grid; east–west highways have even numbers while north–south routes have odd numbers. The lowest numbers are in the east and the north. The east–west highways in Michigan number in the single digits up to the low 20s. The north–south highways range from the low 20s into the 40s. There are also three three-digit highways numbered in the 100s and one in the 200s as branches of related two-digit highways.[8]

In Michigan, the US Highway System covers about 2,300 miles (3,701 km) of mainline highways and another 160 miles (257 km) of

History

Map
US Highway number assignments on November 11, 1926, in Michigan

The US Highway System was approved on November 11, 1926.

US 112S was a suffixed, directional branch
of the US 112 mainline; it was removed a few years[12] after being designated in 1931.[13] Around the same time period, the first alternate routes were designated, numbered with an "A" suffix.[a]

During World War II, the

US 24A in the southeastern corner of the state, which became part of Interstate 75 (I-75) in 1959.[21]

Major numbering changes started in the 1960s as Michigan retired or rerouted its US Highways with the completion of Interstates. US 12 replaced US 112 in 1962 when the I-94 designation supplanted most of the original US 12.[22] Later that year, US 16 was decommissioned in favor of I-96.[23] This trend continued into the 1970s when US 25 was decommissioned as redundant to sections of I-75 and I-94.[24]

Not all freeway conversions of existing US Highways resulted in the removal of US Highway numbers. In 1968, the state submitted a request for additional Interstate Highway mileage to the federal government, including a proposal to convert US 131.[25] This specific project was not approved although the state continued its own efforts to convert the highway, including various segments opened in the 1970s[26] and 1980s.[27] Other highways converted to freeways included US 10, US 23, US 27, US 31 and US 127.[8]

At the end of the 1970s, MDOT took part in a Federal Highway Administration-backed initiative called the Positive Guidance Demonstration Project, and the two agencies audited signage practices in the vicinity of the I-96/M-37 and I-296/US 131 interchange in Walker, north of Grand Rapids. MDOT determined that usage of the I-296 designation was "a potential source of confusion for motorists".[28] Following this program, the Reflective Systems Unit at MDOT reviewed the state of two- and three-way concurrencies along the highway system in Michigan. They approached the department's Trunkline Numbering Committee and the district traffic and safety engineers on October 19, 1982, for proposals to reduce or eliminate the various overlapping designations to "avoid driver confusion and save funds".[29] The initial discussion report included the various remaining overlaps between Interstate and US Highways.[29] When the unit released its final recommendations on March 17, 1983, various changes were proposed.[30] In 1983, US 2 was truncated, removing the overlap with I-75,[31] and in 1986, US 10 was similarly shortened to remove an overlap with I-75.[32] US 33 was all but eliminated in the state in 1986 as well, eliminating its overlap with US 31.[33] Over a decade later, two highway designations were completely removed from the state in 1990s when US 33 and US 27 were truncated to end in Indiana in 1997[34] and 1999,[35] respectively. The latter also removed an overlap with I-69.[36]

Additional freeway sections opened around the turn of the 21st century. The

right-of-way acquisition without any commitments for actual construction.[43] Plans are also still in place to complete the rest of the US 31 freeway near Benton Harbor,[44] but funding has not been available.[45]
