Interstate • US • StateBelow is a list of many County-Designated Highways in Michigan. Unlike State Highways (M-nn), there is a zone system to the numbering of these highways.
“ The basic plan provides for dividing the state into eight zones, lettered from A to H. These zones are determined by major state and federal trunklines which form dividers.
Within each zone, two-digit numbers will designate continuous routes, although each may cross several counties. In some cases, the route number may extend through one or more zones although the letter designation may change.
The numbering system will employ even numbers for East-West roads and odd numbers for North-South routes. Lower numbers, such as 01 and 02, etc., will start at the East or South boundaries and progressively increase to the 90 and 91 levels toward the West and North within each zone.
Thus, a traveler seeking to find A-28 could quicky determine that his destination is in the Southwestern Michigan area and that his route is an East-West road in the central part of that zone.[1]” Contents
Zone system
Lower Peninsula
The Lower Peninsula is divided into 6 zones, A-F:
- The "A" Zone is bordered by I-96 on the north and US 127 on the east.
- The "B" Zone is bordered by I-96 on the south, US 10 on the north and US 127 on the east.
- The "C" Zone is bordered by US 10 on the south and both I-75 and US 127 on the east. Since C-64 and C-66 keep their designations across I-75, it is likely that M-27 forms part of the boundary as well.
- The "D" Zone is bordered by US 127 on the west and I-96 on the north.
- The "E" Zone is bordered by US 127 on the west, I-96 on the south and US 10 on the north. As of 2007[update], no routes have been designated in the E Zone.
- The "F" Zone is bordered by both I-75 and US 127 on the west and US 10 on the south. Since C-64 and C-66 keep their designations across I-75, it is likely that M-27 forms part of the boundary as well.[2]
Upper Peninsula
The Upper Peninsula is divided into the "G" and "H" zones. The dividing line between the two zones is US 41, between lakes Michigan and Superior with Zone G lying west of US 41 and Zone H lying east of it.[2]

A-2
Location: Lake Michigan Beach – Holland A-2 is located in the southwestern part of the Lower Peninsula and runs along near the shoreline of Lake Michigan. It was originally part of US 31 before the I-196/US 31 freeway was built. It was the first county designated highway in the Lower Peninsula.[2] The route's southern terminus is at M-63 in the community of Lake Michigan Beach and its northern terminus is at US 31 south of Holland. The highway remains a two-lane undivided highway for most of its length, with a few divided portions. The highway is about 50 miles long. It has long been referred to by local residents as the Blue Star Memorial Highway in honor of "Blue Star" veterans who served the United States military during World War II.
A-37

A-42
Location: Dunningville–Bradley A-42 runs for 16.4 miles (26.4 km) in Allegan County. The original segments of the highway were designated in 1982.[3] The western terminus of A-42 is at M-40 just north of Dunningville, having been extended westerly from A-37 in 1993. Its eastern terminus is at a junction of US 131 and M-179 near Bradley.
A-42 begins at an intersection with M-40 north of Dunningville. It follows 128th Avenue eastward to 13th Street. A-42 follows 13th Street northward for .75 miles (1.21 km) to a junction with 129th Avenue. From there, it turns eastward again along 129th Avenue to the US 131/M-179 interchange.
A-42 originally continued from US 131 another 6.146 miles (9.891 km) to M-43 west of Hastings.[4] This routing followed Metz, Bowen's Mill and Gun Lake roads. This portion of A-42 was transferred to the state as M-179 on October 31, 1999 as a part of then-governor John Engler's Rationalization plan. This portion was considered for a western extension of M-79, but the Michigan Department of Transportation ultimately decided to use a new designation instead.[3]

This segment of highway is also a relic of former US 2 between those cities. As I-75 was constructed between St. Ignace and Sault Ste. Marie, the US 2 designation was transferred to the freeway with the former route being turned back to local control. In the early 1970s, the former route of US 2 along Mackinac Trail was designated as H-63. H-63 is known as Mackinac Trail for its entire length.
