Wikipedia talk:Manual of Style/Road junction lists

How firm are the destination guidelines?
I'm having a disagreement with another editor over the destinations that should be shown in road junction lists, with the edits occurring primarily in southern New England. I want to make sure that I'm interpreting the "Destinations" bullet in WP:RJL correctly. In my reading, we use the destinations that are shown on the signs in the field, and I interpret that to include what we can see on a Streetview-type application. It appears that the other editor wants to put in the ultimate destinations that the numbered highways lead to, often at the expense of what are actually signed. I've been attempting to engage with the editor about the guidelines, but with little success, and I haven't seen anyone else jump in. So, could someone take a look at the histories of some of the highway articles in question and offer some input? Examples abound; my most recent exchange with the editor is on Massachusetts Route 2A. I've invited the editor to join this discussion. --Ken Gallager (talk) 12:49, 6 May 2020 (UTC)
 * This discussion is better suited to WT:USRD, as it deals with application of the guidelines, not developing them, so I have reposted it there. --Ken Gallager (talk) 13:08, 6 May 2020 (UTC)

Keep 'British style' junction lists!
I disagree with the insertion of standard format road junction lists on articles for motorways in the UK, because I believe they would be more difficult to read compared to what was there previously (eg: compare the list on the M53 motorway with the recently changed one on the M56 motorway).

The benefit of British style lists is that they can work with sequential and distance-based junction numbers, and visualize destinations signed from the junctions along different classes of road, it is only relaying what drivers would see on the ground to keep it straightforward.

 * On the other hand, the MOS-compliant version gives the reader some geographic context to where the road is located in addition to your reasons for keeping the British style. –Fredddie™ 23:00, 3 November 2022 (UTC)
 * There are also accessibility concerns with the older style of tables. --Rschen7754 00:27, 4 November 2022 (UTC)
 * To this Yank's mind, the "British style" wastes a lot of space. The two widest columns in the table impart the same information. I understand that in a dual carriageway, sometimes the exits are not identical between the carriageways. However, IMHO that's spending a lot of space to cover a scenario that is the exception, not the norm. I've always had this opinion, but I've also mostly avoided debating the issue, as I accept there's likely a regional reason many UK Roads editors prefer that format. I strongly suspect that the "British style" originated from the old railroad timetables, common throughout the world when rail was the primary form of travel. The UK style bears both a functional and visual similarity to those timetables. I also suspect that older people might prefer this format, being used to them. However, assuming my origin thoery is correct, if you look at the old railroad timetables, the read up/read down columns were the arrival and departure times, not the destination columns. In that context ordering the data in a read up/read down format on a train table saved space, not wasted it. As such, I prefer the format that imparts more information in less space, which is the "American format" (for lack of a better word). Just my $.02, please take the opinion in the gracious spirit intended. Dave (talk) 00:47, 4 November 2022 (UTC)
 * @Moabdave: there are some older American roadgeek websites that have exit list tables with per-carriageway columns in their tables. They've typically used HTML to replicate the appearance of freeway guide signs complete with colored backgrounds. We're a few layers of translation and abstraction away from that in our presentation and supply much more information, like geographic locations, mileposts, more notes, etc. That content hasn't really caught on with the different websites though, and may of them out there don't include exit lists at all. I agree that the current RJL standard is far superior.  Imzadi 1979  →   23:15, 18 November 2022 (UTC)
 * If the difference between Wikipedia's coverage of a topic verses a fancruft website is "more information, less graphically pleasing formatting", I would argue that's how it should be.Dave (talk) 19:22, 19 November 2022 (UTC)


 * I have converted the UK A14 to the standard format before realising there was a discussion on this. It is currently at sandboxA14 if could someone look and see if I've done it correctly before overwriting the existing junction list? (I have also posted this request to the A14 talk page but not had any response there.) Robertm25 (talk) 22:24, 18 November 2022 (UTC)
 * @Robertm25: looks good to me.  Imzadi 1979  →   23:09, 18 November 2022 (UTC)

Does anyone have a record of which British roads contain standard format road junction lists, which have the "British" style, and which, if any, any other format or none? Robertm25 (talk) 14:10, 19 November 2022 (UTC)
 * I would've cross-referenced the articles using random british road template, but it appears those junction tables are hard coded in some cases, so the answer I can give is "I'unno". It would be difficult to put into numbers. - Floydian τ ¢ 15:31, 19 November 2022 (UTC)

Census designated places in junction lists
and I are in disagreement at Washington State Route 20‎ over the use of Pine Grove, Washington as the location for the junction between SR 20 and SR 21 North. I read the instructions here as to not add a place to a junction that is not in a community at all such a the junction of SR 20 and Old Kettle falls Rd which is outside any incorporated or Census designated place in Ferry County. The 20/21 junction is in the middle of however, and I feel meets the criteria for listing in the table.-- Kev min  § 16:19, 27 July 2023 (UTC)
 * The main discussion is at Talk:Washington State Route 20. As Pine Grove is not listed in the State Highway Log or in other WSDOT resources, it is not verifiable and thus does not belong in the table.  Sounder Bruce  16:21, 27 July 2023 (UTC)
 * Where is that sourcing consensus stated?-- Kev min  §
 * I googled, which in itself is not the arbiter of notability, and realtor.com's definition of Pine Grove is larger than that shown on Google Maps. That and the gas station/truck stop at the intersection of SR 20 and SR 21 is called "Pine Grove Junction", so I think the argument that it's an unverifiable name is weak.  Ultimately, this is a lot of energy wasted on something that just doesn't matter.  I'd leave it in and move on. –Fredddie™ 16:29, 27 July 2023 (UTC)
 * WP:V. I've yet to see a reliable source that outright states that the junction is in Pine Grove; since Google Maps has inaccurate boundaries due to whatever meddling and data they use, I've stopped using them for the locations column.  Sounder Bruce  16:37, 27 July 2023 (UTC)
 * WP:V is not a source for your assertion of consensus that only WASDOT sourcing is acceptable for the table though, which is what I specifically asked for. Is there consensus or is there personal perference?-- Kev  min  § 00:39, 28 July 2023 (UTC)
 * I've yet to see a reliable source for Pine Grove's boundaries. I'm simply using WSDOT's resources because they are of good quality and meet the project's needs. Any unsourced and unverifiable content has to be removed, per site-wide policy.  Sounder Bruce  00:53, 28 July 2023 (UTC)

Missing mile marker template
I remember there being a template for highway junction lists where one or more of the mile markers are missing. I tried to search for it on Google and found nothing. What is the template used? I want to add it to US Route 322.Bubby33 (talk) 19:33, 9 August 2023 (UTC)


 * @Bubby33: mileposts.  Imzadi 1979  →   03:05, 10 August 2023 (UTC)
