Route Map of A-2

Notes:

A-2 was one of the first two County-Designated Highways in Michigan in 1971, at a time when all such highways in the Lower Peninsula were to have an "A-" suffix and those in the Upper Peninsula were to have a "B-" suffix. While a multi-lettered system was adopted (A-F in the Lower Peninsula, G and H in the U.P), A-2 kept its original designation as it fell into the new "A-" territory.

A-2, which runs along the route of Old US-31, is also known as Blue Star Memorial Hwy for its entire length.

History:

1970 - As one of the first two county-designated routes in the state, A-2 is signed via the former route of US-31 (the Blue Star Hwy) from BL I-196 at North Shore Dr north of South Haven to jct US-31 & BUS US-31 on the south side of Holland.

1971 - A-2 is extended southerly via the former route of US-31 from jct M-140 & BL I-196 south of South Haven to US-33 in northern Berrien Co.

1972 (Dec 15) - Phoenix St from Broadway in downtown South Haven easterly to I-196/US-31 at Exit 20 is transferred to state control as part of a rerouting of BL I-196 in the city. Instead of turning northeasterly via Blue Star Hwy on the south side of town, BL I-196 now continues northerly via La Grange St, northwesterly via Phillips St, and northerly along Broadway to Phoenix downtown. BL I-196 now turns easterly via Phoenix St to a new terminus at Exit 20. The former route of BL I-196 via Blue Star Hwy (M-140 to North Shore Dr) and North Shore Dr from Blue Star easterly to I-196/US-31 at Exit 22 remains as an unsigned state trunkline for the time being, but is signed as part of A-2.

1990s? - While a precise transfer date is not yet known, the former pre-1972 route of BL I-196 via A-2/Blue Star Hwy and North Shore Dr is turned back to local control and remains signed as A-2.

2004 - In conjunction with a runway extension project at Holland's Tulip City Airport, the route of A-2 past the western end of the airport is realigned and depressed underneath the new runway in a cut-and-cover tunner project. While highway tunnels under airport runways are not unheard of, one for such a secondary route in a small city such as Holland is quite rare!

Route Map of A-37

Notes:

Contrary to many Ottawa County road maps, including the Ottawa Co Road Commission's own official highway map, A-37 does not continue northerly via 24th Ave from Byron Rd into Jamestown, then westerly via Riley St to 32nd Ave before turning northerly to Hudsonville. In reality (and as signed in the field), A-37 turns westerly from 24th Ave via Byron Rd for one mile before heading northerly again via 32nd Ave.

History:

1977 - The route from Allegan through Burnips to Hudsonville (30th St in Allegan Co and 24th Ave, Byron Rd & 32nd Ave in Ottawa Co) debuts as A-37.

Route Map of A-42

Notes:

On October 1, 1998, the portion of A-42 from US-131 near Bradley easterly to M-43 west of Hastings was transferred from county to state control as a part of the Rationalization process. On April 7-8, 1999, MDOT erected M-179 markers along that portion of the highway, numbered to reflect its proximity to nearby M-79 east of Hastings. In fact, evidence shows MDOT originally planned to designate this route as a westerly extension of M-79 itself, but was reluctant to post a triple-concurrency (M-37/M-43/M-79) through the City of Hastings.

History:

1982 - The east-west route from A-37 south of Monterey in Allegan Co easterly through Hopkins and Bradley to M-43 west of Hastings in Barry Co (via 128th Ave, 12th St & 129th Ave in Allegan Co and Chief Noonday & Gun Lake Rds in Barry Co) is designated as A-42.

c.1993-94 - A-42 is extended westerly from its former terminus at A-37 north of Allegan to M-40 northwest of Allegan.

1998 (Oct 31) - As one of the relatively few jurisdictional transfers as part of the short-lived Rationalization process, all of county-maintained A-42 between US-131 at Bradley and M-43 west of Hastings is transferred to the state and designated as M-179. A-42 remains in tact between M-40 northwest of Allegan and US-131 near Bradley.

Route Map of A-45

Notes:

A-45 runs along the former route of US-131 between the Kalamazoo and Grand Rapids metropolitan areas.

While rather well-signed in Allegan Co, A-45 signage in Kalamazoo and Kent Counties is less well-signed. In fact, no A-45 signage is to be found along S Division Ave north of 60th St in the Wyoming/Kentwood area. Limited funding and lack of overall coordination of these types of routes is mostly to blame.

History:

1972 - The former route of US-131 from BUS US-131 north of Kalamazoo northerly through Plainwell, Martin, Bradley, Wayland and Cutlerville into the Greater Grand Rapids area to M-11/28th St is designated as A-45. This new route runs via Douglas Ave in Kalamazoo Co; 10th, 11th & 12th Sts in Allegan Co; and S Division Ave in Kent Co.

Route Map of B-15

Notes:

B-15 runs much closer to Lake Michigan than any state trunkline in the Oceana County area, and is often used as a scenic alternative.

It is unclear why B-15 was given such a high route designation -- "15" -- in that over much of its route, the highway is the closest primary county road to Lake Michigan. In the "B-region," the lowest odd-numbered routes run along the Lake Michigan shore, increasing as you head inland toward US-127. Indeed, B-15 could have easily been designated B-01, B-03 or B-05.

History:

1971 - A new route, running closer to the Lake Michigan shore than US-31, is designated from US-31 north of Montague westerly and northerly into Oceana Co, past Silver Lake and terminating at BUS US-31 near Pentwater. The route runs via Fruitvale, Whitbeck, Meinert & Indian Bay Rds in Muskegon Co; and 56th Ave, Webster Rd, 48th Ave, Clay Rd, 38th Ave, 36th Ave, Stony Lake Rd, Scenic Dr, 16th Ave, Buchanan Rd, 18th Ave, Scenic Dr, Hazel Rd, 34th Ave, Ridge Rd & Long Branch Rd in Oceana Co.

1975 - The central portion of B-15 is rerouted to an alignment closer to the lakeshore in Oceana Co south of Stony Lake. The route is removed from 48th Ave, Clay Rd, 38th Ave, 36th Ave and Stony Lake Rd and moved onto Webster Rd and Scenic Dr.

Notes:

B-31 between M-46 and M-120 was formerly a state trukline highway designated M-213, from the mid-1930s until 1960.

In its northernmost portion, B-31 travels along the Muskegon/Newaygo Co line and is, therefore, listed as being in both counties below.

History:

1971 - One in a slew of Muskegon Co-based county-designated routes from the program's first full year, B-31 is designated northerly from I-96 at Nunica via 112th Ave in Ottawa Co and Maple Island Rd in Muskegon Co and, farther to the north, straddling the Muskegon/Newaygo Co line.

In Muskegon Co, B-35 continues northerly via Ravenna Rd (William, Main & Mortimer Sts within Ravenna itself), easterly via Bailey Rd and northerly along Squires Rd. In Newaygo Co, B-35 runs via Alger Ave, 128th St, Luce Ave, 118th St and Warner Ave via Bridgeton, terminating at M-82 three miles south of downtown Fremont.

Map:

Route Map of B-72

Notes:

In essence, B-72 picks up where M-57 leaves off, serving as a connection with Sparta and Ravenna, and as an alternate route into Muskegon.

During its trip through Ottawa and Muskegon Counties, the route of B-72 is very well signed and easy for motorists to follow, while signage in Kent Co is present to a lesser extent.

History:

1971 - B-72 debuts between Muskegon and the "Cedar-Rock" area in northern Kent Co via Ravenna and Sparta. Beginning at US-31 on the southeast side of Muskegon, B-72 runs easterly via Sherman Blvd, Black Creek Rd and Heights-Ravenna Rd into Ravenna, where the route follows Muskegon, Main & William Sts. Continuing southerly from Ravenna concurrently with B-35 along Ravenna Rd, B-72 then turns easterly again via Ellis Rd (Muskegon Co), Gooding St (Ottawa Co) and 13 Mile Rd (Kent Co) and into Sparta. Within Sparta, the route runs via Division St then continues easterly via 13 Mile Rd, northerly via Edgerton Ave and eastelry again via 14 Mile Rd, terminating at the new northern end of the US-131 freeway extending northerly from Grand Rapids.

In a sense, B-86 serves as a westerly extension of M-82, as the route picks up where M-82 leaves off and continues westerly to US-31.

In its easternmost portion, B-86 travels along the Muskegon/Oceana Co line and is, therefore, listed as being in both counties below.

Route Map of B-96

Notes:

With the redesignation of B-88 as a relocation of M-20, B-96 remains Newaygo and Mecosta Counties only east-west County-Desigated Highway. If the Newaygo and Mecosta County Road Commissions get together, a new county designation, such as B-90 or B-92 could very well be assigned to the former M-20 between M-37 and US-131. However, seeing as no extra funding exists for such a project and inter-county cooperation can be hard to come by, don't expect any such designation soon...

Notes:

While county routes C-38 and F-38 are essentially one through highway, they have different letter prefixes for a good reason: Old US-27 is the dividing line between the "C" and "F" designations in Northern Michigan.

C-38 is known as Mancelona Rd for its entire length, named as such in both Antrim and Otsego Counties.

Route Map of C-42

Notes:

In the late-1980s, C-42 and F-42 route markers were added to M-32 and BL I-75 marker assemblies through the City of Gaylord attempting to signify a connection between C-42 west of Gaylord and F-42 southeast of Gaylord via M-32 and BL I-75. Many of these signs existed into the late-1990s, but have been removed in subsequent re-signing projects.

C-42 is becoming an ever more-popular "shortcut" route between US-131 and I-75 for motorists heading "Up North" from the Grand Rapids and Cadillac areas bound for the Mackinac Bridge and the Upper Peninsula. Traffic volumes on this highway have been increasing over the years.

Map:

Route Map of C-48

Notes:

Depending on how one looks at it, there may be a very short gap in C-48 between M-75 just west of Boyne Falls and US-131 on the north side of town. However, MDOT has erected numerous signs along M-75 and US-131 directing C-48 traffic along those highways through Boyne Falls.

There is some question as to the precise eastern terminus for this highway. While the most trusted maps indicate C-48 turning southerly via Old 27 to end at I-75 at Vanderbilt, acutal signage in the area proves inconclusive (although, that seems to be the case more than not). Even MDOT fails to include C-48 route markers on its Exit 290 signage along I-75.

A story in the September 18, 2005 edition of the Traverse City Record-Eagle notes local officials from municipalities in southwest Charlevoix and northwest Antrim counties are interested in petitioning MDOT to extend M-32 westerly from East Jordan through the Ellsworth area to US-31 near Atwood, once again restoring the route as a true "cross-peninsular" highway. Some of the officials are considering asking MDOT to assume control of what is now designated C-48, however the route is currently not up to state trunkline standards throughout, so additional upgrades would be necessary before it could receive the M-32 designation. The article also noted: "Five local governments in Antrim and Charlevoix counties passed resolutions in favor of M-32's extension, with another three expected to take up the issue soon."

Map:

Route Map of C-56

Notes:

This route follows the northern shore of Lake Charlevoix between Charlevoix and Boyne City.

Contrary to some maps and other publications, it is C-56 which occupies Charlevoix-Boyne City Rd between Charlevoix and Horton Bay. A few sources incorrectly claim the C-71 designation bends west at Hortons Bay instead of ending there.

Oddly enough, MDOT has chosen to concurrently sign C-56 along two blocks of M-75 in downtown Boyne City. C-56 enters the downtown area via Lake St, then turns easterly via State St for two blocks to meet M-75 at the cnr of State & East Sts. Instead of terminating here, MDOT signs both M-75 & C-56 southerly via East St for two additional blocks to Water St, where C-56 terminates and M-75 turns southeasterly toward Boyne Falls.

Route Map of C-58

Notes:

Known at Mitchell Rd (Emmet Co) and Wolverine Rd (Cheboygan Co) for its entire length, except within the Village of Wolverine.

As with other county highways, there has been some question as to the precise western terminus for this highway. Although C-58 should logically continue west on Mitchell Rd/St to end at US-31 in downtown Petoskey, the city has not erected any C-58 markers, nor has MDOT along US-31 at the Mitchell St intersection. West of the C-81 jct east of Petoskey, all C-58 route markers taper off, suggesting C-81 is the de facto western terminus for this route. Once again, poor signage is a hallmark of the County-Designated Highway system, so a lack of signage doesn't necessarily indicate a lack of a designation, but for the purposes of this site, C-81 has been chosen as the western terminus.
