Talk:Cantilever bridge

message: I'm somewhat confused about the longest span list. Where did the list come from? Is it just us sticking bridges in as we know or did it come from somewhere? If the latter maybe sourcing more specifically is a good idea?
Also is there any merit to a longest total span list?  Consider Poughkeepsie Bridge. It has several spans that are in the 500 foot range. Some are not cantilever, it uses a pattern of fixed truss, cantilever, truss, cantilever, etc... Should it be listed in such a list, since it has 3 cantilevers. I'm guessing no merit to such a list but wanted to float the idea. ++Lar: t/c 18:34, 16 January 2006 (UTC)

The article says in the table that the descendant of this brigde is "Cantilever spar cable-stayed bridge", but I think that the descendant of this brigde is "Cable-stayed bridge", whith normal spars.--Magnus Colossus 01:02, 21 June 2006 (UTC)

message: I have added a photograph of Vejlefjord Bridge because it is a cantilever brigde, but it isn't the tipical truss cantilever brigde. The footnote is very simple beacuse I can't speak a very complex english, and i can't write more text.
* From the looks of it, I don't think the bridge is a cantilever. Can someone please try to explain why it is a cantilever. Otherwise the photo should be removed.
::This bridge is probably a cantilever - it is similar in appearance to a bridge under construction in Northern California That bridge is being constructed by first placing footings, then erecting columns, and then building in balanced fashion out from the columns using cast-in-place tubular sections, forming a balanced cantelever at each column, which are extended until they meet. - Leonard G. 01:26, 23 July 2006 (UTC)
replies: text:  I've amended the image caption to make it clearer - it's a balanced cantilever bridge, i.e. cantilevered during construction only, although not once completed. I think it would help the article a lot to split out bridges which are cantilevered only during construction into a separate article. I'll see if I can find some time. -- Kvetner 08:43, 12 April 2007 (UTC)

message: It appears that Captain Elisha Huntley Mack was the first person to invent or discover the cantilever bridge, rather than Heinrich Gerber. It was during the time frame he built the 1st dam at Turners Falls in 1793, long before the first patent listed in this article. I read he died while in Washington D.C. planning to apply for a patent and I can't help but wonder what the patent was for. Refrences:

replies: text: The sources are problematic because they are local histories rather than histories of bridges per se.  Local histories tend to ignore things outside their scope, so all the sources are good for is citing instances (and pointedly, using fewer words here than in the source), rather than asserting something was done first. A paragraph in a source like that amounts to a sentence here. TEDickey (talk) 22:37, 22 March 2015 (UTC)

text: By the way, your use of <ref> tags interferes with other editor's comments TEDickey (talk) 22:39, 22 March 2015 (UTC)
replies: text: This is my first contribution and I apologize for my ignorance. I removed the ref tags but I used them because I see below, "cite your sources" with ref tags. I also apologize for not responding earlier. I didn't get notice of a reply. I see your point but I'm wondering how this information could be found within a history of bridges unless the compiler read these local town histories. I've searched and don't find this kind of source. I am not sure what all would be considered a valid source for this. If there were an article published in the local newspaper describing this bridge, would that be considered a valid source? It was certainly newsworthy. AquarianEssence (talk) 20:08, 6 April 2015 (UTC)

text: Local newspapers have the same problem: they are local, written for local interests.  That tends to undermine any discussion of what was first.  A published article or book (by a knowledgeable historian) of the overall topic which discusses the structures would help. TEDickey (talk) 22:46, 8 April 2015 (UTC)

message: An editor made an edit with an edit summary saying: Examples: rm half the gallery. We need better photos, and side-on to show cantilevers. Some of these are nice images, but they're not encyclopedically illustrative.
I disagree. In my opinion, the article need images that show this bridge type from different angles. If the article is only going to show cantilever bridges from one viewpoint, there might as well just be one photo in the entire article. Toddy1 (talk) 19:05, 1 April 2020 (UTC)

message: what exactly does "continuous across multiple supports" mean?   It wouldn't be a bridge if it wasn't continuous would it?
(I'm guessing it refers to the structure supporting bending at the supports and someone has gone too far trying to avoid technical language? )

message: In the article on the Ambassador Bridge, no mention is made of the design life of the bridge. I heard that the bridge has exceeded this age. 2600:1700:6A10:84B0:8584:78A2:AC5A:D477 (talk) 22:32, 9 February 2022 (UTC)
