Talk:List of state highways in Maryland

Naming conventions
According to it's the State Highway System, but everything is a State Route or numbered route. Routes are apparently referred to as MD X. (Google search for MD 140 vs. Route 140) I propose "MD X" as the name for articles. --SPUI (talk - don't use sorted stub templates! ) 06:16, 7 March 2006 (UTC)
 * Page 2 of that document refers to them as "state highways", however. Also, I've always understood them to be officially known as state highways.  As for the individual names, "MD X" is an abbreviation.  Expanded they are "Maryland X" (as indicated on the route markers).  The SHA likes to abbreviate apparently.  I'd support renaming the articles to "Maryland X", but I guess we'd have to see how the NC debate turns out.-Jeff (talk) 04:02, 9 March 2006 (UTC)

"State Road No. 1"
It appears there was such a thing before any of the other numbered routes existed. I cannot find evidence of any other state roads from that era.

From 1908 ch. 304 sec. 1:
 * A public highway to be known as State Road No. 1 shall be constructed between the cities of Washington and Baltimore, the course of which, as near as practicable, shall be along the route of the old Baltimore and Washington Road; provided, however, that said State Road No. 1 shall be constructed upon the present roadbed of the Baltimore and Washington Road from Waterloo, in Howard County, to the Village of Halethorpe, Baltimore County, and entering the City of Baltimore at Columbia Avenue, the bed of which, so far as the same is vested in the State or the several counties through which it passes, hereby dedicated by way of easement or fee simple, as the case may be, to the public use.

Obviously this is now mainly US 1 between Baltimore and Washington. Columbia Avenue is now Washington Boulevard. --NE2 12:46, 12 August 2006 (UTC)

More info on MD 1, according to that it was probably never signed, I would mention the route in the U.S. Route 1 in Maryland article (with Maryland Route 1 being a redirect to it), but that article doesn't exist yet (nor have I gotten around to creating it).-Jeff (talk) 01:58, 17 September 2006 (UTC)


 * I mentioned it in U.S. Route 1; that can be moved when U.S. Route 1 in Maryland is created. --NE2 06:40, 17 September 2006 (UTC)

When did numbering begin?
Routes were numbered by July 1930:   And apparently by June 1929, though that article only seems to describe 2, 3, 5, 13, 113, and 213. --NE2 01:17, 20 June 2007 (UTC)

Here's a 1929 map that includes 2, 3, 5, 6, 12, 16, 17, 18, 19, 20, 22, 23, 24, 25, 26, 29, 31, 32, 35, 36, 37, 313, and 413: --NE2 08:17, 20 June 2007 (UTC)


 * MDroads says "Maryland began numbering in the early 30s", that's probably an estimate, so it makes sense that numbers would appear on a 1929 map. Then there's also MD 1 which appeared over 20 years prior.  MDroads also mentions that it was not until 1942 that route numbers were required to be signed.  As for the exact year numbers first appeared, looking at those old maps it would seem to have happened between 1923 and 1929, most likely towards the end of the decade considering MDroads' estimate was "Early 1930s".-Jeff (talk) 15:23, 9 July 2007 (UTC)

Where is MD 496?
MD 496, which runs between roughly between Westminster and Manchester doesn't appear in Wikipedia. Is there a reason for this? Leebert 00:37, 3 August 2007 (UTC)
 * Because no one added it yet, I went ahead and added it myself. This list isn't exactly complete so if anyone sees something missing please go ahead and add it.-Jeff (talk) 03:12, 17 August 2007 (UTC)
 * Ahh, thanks, Jeff. I thought perhaps there was a reason it was excluded.  Leebert 02:46, 19 August 2007 (UTC)

Need map graphics for MD Roads in Charles County
Hi! I'm a resident in Charles County, and noticed a lot of the state highways in my county were missing, so I've started the process of adding them (Including a Template:Roads in Charles County, Maryland section I've added to all the state highways currently in the county (all or partly). However, the only thing I'm missing is the maps that User:Algorerhythms has put up.  If I knew how he was making them, I'd add them myself, as they look relatively simple.  But It looked like he's got the process down pretty good, so I thought I'd post here and see if anyone can get those hooked up.  I'll be adding more state highway entries as I get the time, but if anyone's bored, please check out what I currently have added for accuracy and any other oddities I may have missed.  I'm also a bit new to Wiki editing, so pointing out any mistakes will help me learn! (and excuse my use of the 'Minor Edit' flag on a few entries, I didn't realize what that was for initially).

If I get the time to do the research, I'll probably also setup a Template:Roads in St. Mary's County, Maryland and a Template:Roads in Calvert County, Maryland since some of the roads in Charles cross over.

 * I was going to make those maps tonight, actually. What I've seen of what you've added so far looks pretty good. - Algorerhythms (talk) 17:20, 25 June 2008 (UTC)
 * Neat! Out of curiosity, what do you use to make those?  I figure you're at least getting the raw map itself from somewhere that not covered by some kind of license (like Google or Yahoo). Kumba42 (talk) 02:05, 26 June 2008 (UTC)
 * I use a program called QuantumGIS, which generates maps from data that I get from various sources (some of which are listed on my userpage). Incidentally, the way I got started with Wikipedia was that I noticed that most of the state highway articles for Allegany County were missing, so I started adding them. - Algorerhythms (talk) 02:21, 26 June 2008 (UTC)
 * Ahh, neat. I assume that lets you control just how many roads are visible when you generate the images.  I've done a few edits here and there, but I guess boredom shows itself in strange, yet useful ways.  Plus this lets me lock down in my head the local roads a lot better. Kumba42 (talk) 03:50, 26 June 2008 (UTC)
 * It does let me control how many roads are visible, though the data file I usually use (the National Highway Planning Network data) contains only Interstates, U.S. Highways, and a few select state highways. - Algorerhythms (talk) 03:53, 26 June 2008 (UTC)
 * Added two more full articles numbered routes tonight, MD 234 and MD 425, so when you get free time, they can use maps as well. I'll add some more routes tomorrow (3am for me).  Thanks! Kumba42 (talk) 07:06, 26 June 2008 (UTC)
 * MD 254, MD 257, and MD 488 added. Thanks! Kumba42 (talk) 21:25, 27 June 2008 (UTC)

MD 925's true length?
This one's got me confused. Locally, the entire portion of Old Washington Road in Waldorf, from Billingsley Road north to US301 (about ~5 miles) is regarded as MD 925. According to the HLR, though, Route 925 itself stops at MD 5 BUS (Leonardtown Road), while Old Washington Road itself continues onwards to the US 301 junction (and there's even a little dead-end stub beyond that). This is new to me, as I always thought the whole route was 925, but I'm deferring to the HLR on this and updated the Infobox and article to reflect the terminuses (terminii?). However, all the major mapping services (Google, Yahoo, Microsoft, and Mapquest) sign the entire route as MD 925.

So if we defer to the HLR, then the map on the page needs to be updated to stop at MD 5 BUS, but I wasn't sure whether this was necessary here. Which takes true precedence? the HLR, or local knowledge that's probably unaware of some minor curiosity? Kumba42 (talk) 18:06, 29 June 2008 (UTC)

Reformatting
I've noticed that the list takes a ridiculous amount of time to load, and the page size is massive, so I have reformatted the list using the jct templates. There are some exceptions, though, like with US 40 ALT, which is did not change because they would break. Hope this helps. --Onore Baka Sama (talk) 20:09, 19 December 2009 (UTC)

List of unused highway numbers
Is there an article which lists those numbers not used for Maryland state routes and the reason why the number isn't used? I understand primarily it's because of a U.S. route with that number, or a highway has been decommissioned, but it would be useful (I think) to have them all in a list. 216.81.94.70 (talk) 16:44, 15 July 2014 (UTC)
 * There is no such list because (1) there remains much research to be done to claim our coverage of state routes is near complete and (2) it is very difficult to prove a negative. From a proof standpoint, it is easier to list all of the numbers that have been used, which will be implied by this list once it is complete or close to complete with former routes.

Missing

 * MD 43 #1- probably MD 38 Altamont to Swanton
 * MD 44 #1
 * MD 46 #1- probably Westernport to Virginia
 * MD 54 #1- probably Cumberland to West Virginia (became part of US 220 in 1930)

MD 956 was MD 9?
according to [], MD 956 was originally MD 9. Can someone please confirm whether this was MD 9 or not?Alexlatham96 (talk) 02:26, 15 August 2019 (UTC)
