Talk:List of county-designated highways in Michigan/Archive 1

Zone Boundaries
It's likely the zone boundaries were established with reference to the U.S. Highway system that existed before the Interstates came along. U.S. Route 16 was replaced by I-96, while U.S. Route 27 has been replaced by M-27, I-75, and US 127. Caerwine Caer’s whines 17:54, 14 August 2007 (UTC)
 * US 16 was already long gone in Michigan by the time the CDH system was developed. US 27 still existed though. Imzadi1979 01:32, 15 August 2007 (UTC)

Consolidation
Consolidation of the numerous stub articles (individual highways) into fewer, larger articles, one per zone, has been proposed at Wikipedia talk:WikiProject Michigan. If you wnat to comment on this proposal, please post something there. -- John Broughton (♫♫) 22:18, 24 February 2007 (UTC)
 * In the process of implementing this. —Scott5114↗ 01:40, 12 October 2007 (UTC)
 * I've proposed at WP:USRD/SUB the creation of a taskforce under WP:MISH dealing with the county-designated highways and any other notable county roads in MIchigan. Some of these articles currrently merged into the list can be recreated as stand-alone articles and expanded. Imzadi1979 (talk) 19:20, 5 April 2008 (UTC)

Recent edits
I reverted a recent pair of edits that added an "M-zone" to the article. My reason is that such a thing is patent nonsense. First off, the original system was just two zones, A in the Lower Peninsula and B in the Upper Peninsula. It was expanded to A-H zones. I-X in Michigan is the abbreviation for Interstates, so for there to even be close to an "M-zone" MDOT would have needed to skip I and set up J-L zones, which they didn't do.

A2 is misnumbered?
CR A2 seems to break the numbering convention; it is a north-south highway and yet carries an even number. If anyone can determine why, I'd like to see this information added to the article. Lord Geznikor (talk) 20:28, 5 January 2012 (UTC)
 * What is now H-40 in the UP was B-1 on the 1970 map, and A-2 was A-2. That map was labeled with boxes pointing to each route. The boxes read: "Experimental program for identifying key county roads—if found to be beneficial to the motorist, additional routes will be added to future maps". As we know from two articles in the Holland Evening Sentinel that year, the numbering scheme was expanded to the current six-zone system. The genesis of the program was a woman who owned a motel on Blue Star Highway (previously US 31, now A-2) who found that her potential customers couldn't find her business once the freeway was built and the US 31 markings were shifted on the maps and signs. The educated guess is that A-2 was grandfathered in as an exception rather than convert it to the post-1970 zone system. I'm working on the history to expand the lead of this article further.

New table coming
I've been working on converting this list to a table in a sandbox using the templates developed for WP:USRD/STDS/L. In doing so, I've gone through all of the official state maps since 1970 to confirm the various years. There are several entries on here that have never appeared on a state map, so they'll be removed in the transition. They are:


 * Both F-07s
 * F-09
 * F-17
 * F-24
 * H-09
 * H-60

In addition, F-18 and F-28 were removed and then re-assigned in shorter form, so they will each have two rows to reflect the two versions of each. If anyone has actual maps showing the years the listed highways debuted and were removed, I'd be open to restoring them to the list, but as of right now, there's no sources for their existence. I just need to pull up the lengths for the rest of the Cs, and the Fs before I copy the table over.  Imzadi 1979  →   09:56, 11 August 2015 (UTC)


 * I just switched over to Harvard-style referencing for the various MDSH/MDSHT/MDOT maps being cited. All that is left should be to compute the lengths off MDOT's Physical Reference Finder Application, and in the process, determine the exact townships or other municipalities at the termini for the rest of the Cs and the Fs. I should be able to get to that later today or tomorrow.  Imzadi 1979  →   10:08, 12 August 2015 (UTC)

Total length calculation
To compute the total length of the system, I added up the lengths of all current (as of 2015) CDHs. This gave me 1,246.225 mi. From that figure, I subtracted the length of the four concurrencies on the system:

"The Ogemaw County Routes"
So... how does anyone want to handle what I've termed "The Ogemaw County Routes" in this listing of Intercounty Highways? The "usual" method of dating the existence of highway routes using official state highway maps—which in and of itself has shortcomings—falls pretty flat here. I do feel for anyone trying to put together articles on Wikipedia with so little in the way of primary or secondary sources on these routes, but if anyone wants to give https://www.michiganhighways.org/county/ogemaw_routes.html a read, it's clear these routes are still alive and... er, maybe not "well," but definitely still signed in the field. The page even has photos of extant route markers, so it's a real thing. In one example, F-18, the route markers were never removed in the 1980s and are still there to this day, so to list it as two separate routes—one ceasing to exist in 1984 and a new one "recommissioned" in 2003—is definitely not true or accurate. Could my page be considered an appropriate source? I know a Wikipedia editor is barred from "original research" but I've done the research and posted the findings on my site... No newspapers or other "citable" sources are necessary... just saying... CBessert (talk) 03:03, 4 September 2023 (UTC)
