Talk:APD-40

needs-jctint
I just converted the table to use TNint, yet the banner said it didn't need to be converted because no was incorrectly set.

In any case, the junction list needs location information, mileposts and some copy editing to make sure that the formating in jct is correct. I trust that someone familiar with the area can handle that. I can assist with the technical side of things though.  Imzadi 1979  →   19:23, 27 March 2014 (UTC)
 * I'm familiar with the area, but the problem is, this made up of different numbered highways, and is rarely referred to by them. The entire loop is simply referred to as "APD-40."Bmag32 (talk) 02:09, 4 May 2014 (UTC)
 * that may be, but the table needs the locations added. For example, is the I-75 interchange within the boundaries of a city or village? If so, that city or village should appear in the location column. If this roadway passes through multiple counties, a County column is needed. M-553 (Michigan highway) shows a high-quality, single-county junction list, and M-6 shows another high-quality junction list for a highway in multiple counties. (Just ignore the exit column for M-6.) Mileposts should be given showing the distances along the highway as well.  Imzadi 1979  →   03:34, 4 May 2014 (UTC)
 * I've added some map references, if that helps.75.138.44.170 (talk) 16:19, 7 July 2014 (UTC)
 * The one allowed me to insert the missing locations, however we still need to add the missing mileposts.  Imzadi 1979  →   19:11, 7 July 2014 (UTC)
 * And citations for the history. What I wrote came from old copies of newspapers I own, and I have displaced them since and have not yet been able to find them on Google News. But I am still looking. The mileposts will be difficult to find, but they might could be found by measurements on the Google Maps source.Bmag32 (talk) 05:55, 8 July 2014 (UTC)

OK, but what's the 40?
Appalachian corridors are lettered, not numbered. What's the 40 supposed to represent? If it's named after State Route 40, why doesn't it follow that route to the North Carolina line? --NE2 18:17, 28 March 2014 (UTC)
 * This is the name of a highway that is part of corridor K, not the entire corridor. In fact the TN-60 section of the road isn't even part of the Appalachian Highway system at all; it just takes that name because it was built about the same time. There's not much out there about the history of this road. The "40" may have something to do with SR-40, but it seems I read somewhere that it stands for "Appalachian Development #40." This article needs additional citations, maybe some newspaper articles from Google News.Bmag32 (talk) 02:09, 4 May 2014 (UTC)

 * Where does http://www.tdot.state.tn.us/projectplanning/studies/APD40IJSBRADLEYCOReportwithAppendix.pdf support the facts being cited (I-75 to South Lee Highway was built in 1968, and the original plan ending at US 64, with SR 60 moving)? --NE2 23:13, 16 November 2014 (UTC)
 * Also, the link you added ("Appalachian Highway Finally Completed, After Six Long Years") is broken. --NE2 23:17, 16 November 2014 (UTC)


 * Figured it out: according to the US Geological Survey, the first section was originally signed as part of State Route 40 and remained that way for at least a few years. 146.229.240.200 (talk) 09:34, 13 November 2017 (UTC)

Does the secondary part of SR 311 still exist?
http://www.tdot.state.tn.us/maps/city/Cleveland.PDF shows SR 311 leaving the bypass onto Dalton Pike to end as SR 74. It doesn't appear to be signed, but that doesn't mean it no longer exists. --NE2 16:26, 8 November 2014 (UTC)

Dates
According to USGS maps, the first section of APD-40, located between I-75 and US 11/64, may have been in existence as early as 1965. However, that's not consistent with the dates engraved on the rails of the bridge over South Lee Highway, even though that may not have been built with that section. I wish I had seen the date on the old bridge over I-75 before it was demolished. All of the dates in the article are consistent with the dates on the bridges. The 1965 date also seems unlikely because I seem to remember a Cleveland map I own from 1968-69 that seems to show it being under construction then, and its unlikely it would have taken 3-4 years to build that short section. However, the USGS I think is sometimes known to include routes that are proposed or under construction as complete. It certainly appears to have done that in its relief map from 1970, saying I-75 was complete through all of Tennessee, when that's totally inconsistent with other maps I own.146.229.240.200 (talk) 07:57, 13 November 2017 (UTC)


 * Update: 1965 is around the time I-75 was built between Chattanooga and exit 25 (SR 60 interchange) - that's what the dates engraved on the bridges say. Also, the Humphrey Bridge road bridge over APD-40 between I-75 and S. Lee Hwy. appears to have been built in 1965, even though it may have existed before or been built in preparation for APD-40. I don't think it would have been built by the state. 146.229.240.200 (talk) 08:03, 13 November 2017 (UTC)

Designations
An IP user keeps removing and replacing the SR 60 designation with SR 311 in the infobox. It should be noted that SR 311 is a state designation for part of the signed US 64 Bypass segment (see Tennessee State Route System), is unsigned, and is therefore insignificant. The SR 60 designation is more important, as a segment of the route known as APD-40 is signed entirely as SR-60, nothing else. This article is about the route containing both designations, not just the US 64 Byp/SR-311 segment. The fact that "every other article on Wikipedia" has it is irrelevant, and, in this case, a straw man.Bneu2013 (talk) 02:42, 20 November 2018 (UTC)

Map
Could someone who is more experienced with maps find a way to replace the bad image that is currently in the infobox with the KML file? It would also be nice if we could color code the US 64 Bypass and SR 60 segments, similar to what is done for the Pellissippi Parkway map. Bneu2013 (talk) 09:20, 27 July 2023 (UTC)
