Business loops and spurs of the Interstate Highway System use a special green version of the standard Interstate marker which places the word "Business" at the top where "Interstate" would otherwise appears. These business loops and spurs connect downtown districts to main highways after realignments and bypasses have routed the main highway out of the downtown area. Another category, connector routes, serve to connect two highways as their names suggest; most of these connectors are unsigned. The highways names for special routes are formulated by prefacing the parent highway with the type of special route. The full names are commonly abbreviated like other highways: Business Loop Interstate 196 (BL I-196), Business M-60 (Bus. M-60) or Connector M-44 (Conn. M-44). As of 2010 there are 9,669 miles (15,561 km) of state trunklines in Michigan, making up about eight percent of the state's roadways. Of that mileage, some 4,415 miles (7,105 km) of state-maintained highways are included in the

For fiscal year 2013, MDOT has budgeted approximately $ 1.2 billion on the highway system, including $ 273.4 million in routine maintenance. The remainder financed major projects in terms of planning, right-of-way acquisition or construction. In terms of winter maintenance, MDOT classifies all state highways into two priority levels for snow removal, authorizing overtime to clear some highways in the state.

Seizing the opportunity brought by a 1957 state law, the department sold $ 700 million in bonds (equivalent to $ 5.81 billion in 2023) in the late 1950s and early 1960s to finance land purchases and construction of the new freeways. The first Interstate Highway in the state was signposted in October 1959 when I-75 signs were first installed along the Detroit–Toledo Expressway. These signs replaced US 24A signage in the Monroe area, after the state received final approval for the numbering system to be used in the state.

Legislation in the 1930s consolidated control of the state trunklines in the state highway department. During the 1940s, the first freeways were built in Michigan. With the introduction of the Interstate Highway system in the 1950s, the state aborted an effort to build the

Other county systems are designated and maintained in each of the 83 counties, and signage and numbering practices vary.

September 2020. US 31 was rerouted to follow its new freeway section for 1.8 miles (2.9 km) from the previous end of the freeway at Napier Avenue that opened in 2003 to I-94 at BL I-94, where US 31 then followed I-94 to the I-196 interchange as before. This new routing opened on November 9, 2022.

legislation redefined the exact distribution, but Act 51 set up a system to distribute road funding from gas taxes from a single funding source, currently the
Michigan Transportation Fund. Funding was increased during the 1950s as the fuel taxes were increased. Whereas those revenues during the war dropped to levels barely sufficient to keep existing highways in usable condition, they were increased during the following decade to deal with increasing traffic. The state highway department was also authorized to sell bonds to provide funding for the proposed road improvements.
