There are six current and former highways related to M-21 in the US state of Michigan. All of these roads have been part of the M-21 at some point. Of these, two are no longer part of the state trunkline highway system, M-21A and M-210. M-56 is part of M-21 currently, and half of Business M-21 (BUS M-21) is now Business Spur Interstate 196 (BS I-196). Bypass M-21 (BYP M-21) was replaced by M-21, and it is now part of M-11 and M-37/M-44. M-121 was previously an unsigned state highway that was called OLD M-21, but since 2007, it has been signed once again.

M-56 was a state highway from 1971 to the mid 1980s that replaced the M-21 designation from M-13 to Flint when the M-21 (now I-69) freeway was built.

When the M-21 designation was replaced with the I-69 designation, the M-56 designation was retired and M-21 was restored in its place. In the 1950s, M-56 was originally numbered on a road from US 25 in Flat Rock to US 112, today US 12, in Canton. Today, this road is known as Huron River Drive and Belleville Road.

Length: 12.763 mi[7] (20.540 km)
Existed: 2007–present

M-121 is a state trunkline highway in the US state of Michigan. A portion of former M-21 in Ottawa County was designated in 2007 as M-121, which was formerly designated as state-maintained "Old M-21". The highway follows Chicago Drive running parallel to I-196. Portions of the four lane divided surface access highway will become four lane undivided as the westbound lanes are shifted south away from unstable soil and parallel train tracks.

Location: Pewamo
Length: 1.928 mi[7] (3.103 km)
Existed: 1933[10][11]–1939[8][9]

M-210 served as a loop route through Pewamo starting in 1933. Motorists traveling on M-21 could get on M-210 to go through Pewamo and return to M-21 on the other side of the town, or stay on M-21 and go around the town.[12] Previous to being M-210, the roadway was a part of M-21; it was assigned M-210 when M-21 was shifted to bypass Pewamo.[10][11] The routing was turned over to local control in 1939.[8][9]
