M-143, also known as Michigan Avenue, is an unsigned spur state trunkline route in the south central region of the U.S. state of Michigan. The M-143 portion of Michigan Avenue runs from the East Lansing city limit to a junction with M-43 at Grand River Avenue.

[edit] Route description

Michigan Avenue travels through the Greater Lansing area on an east-west axis which runs through the Capitol Building in downtown Lansing. While discontinuous from Martin Luther King Jr. Blvd. and Capitol Avenue in the downtown area, the eastern portion of Michigan Avenue begins at the Capitol and runs easterly, ending in downtown East Lansing. For much of its length in the City of Lansing, Michigan Avenue is a five-lane thoroughfare maintained by the city. Just west of US 127, the street transitions into a six-lane boulevard and proceeds easterly to the East Lansing city limit. From that point easterly for one mile (1.6 km) to M-43 at Grand River Avenue in downtown East Lansing, Michigan Avenue is state-maintained as a four- to six-lane boulevard designated M-143.

[edit] History

[edit] Previous designation

From 1931 to 1960, M-143 was designated from US 27 (now M-27) south of Cheboygan eastward for about a mile to the original Cheboygan State Park.

[edit] Current designation

M-143 has been unsigned in the field since the portion of Michigan Avenue within the City of Lansing was transferred to the city, as the Michigan Department of Transportation plans to initiate a similar transfer of jurisdiction for the East Lansing portion in the future. In addition, if signed, the remaining segment of M-143 would terminate at a corporate boundary on its western end, a confusing situation the transportation department has a policy of avoiding.
