Image series converted to Gallery
I noticed that someone introduced a series of images of the same bridge in operation. Later, someone added a new picture, not realizing they were interrupting a series. To avoid this, I've converted the series of images into a gallery. Sizes may not be right, the conversion may not be appropriate, and the images themselves may be too much, but I'm not making that call. - Denimadept (talk) 04:45, 3 July 2010 (UTC)

Panama
There are two swing bridges over the Panama Canal, one is located at Miraflores Locks, the other at Gatun Locks. The Miraflores one is actually larger, t is on the Pacific side, and is rarely used, having been supplanted by the Bridge of the Americas and the Centennial Bridge. The Atlantic Side road crossing is a very small bridge that swings from the sides, not the center. Not sure if that qualifies in the same way, both sides swing out and meat in the middle (like a sideways bascule). You can see a picture of the Gatun Bridge here, and here is it closed. Here is a pic of the Miraflores swing bridge, which is more the classic style described in the page. Aapold (talk) 14:29, 28 December 2010 (UTC)

New image needing placement
I'm not a regular at this article, so will leave it to others to place or not place this new image. Anna Frodesiak (talk) 06:45, 25 July 2012 (UTC)

History
What and where is/was the first swing bridge in the world? A quick web search didn't find anything definite. The bridge in Newcastle upon Tyne is listed in several places as the world's first (see, e.g., http://www.solarglide.com/media/blog/the-worlds-first-swing-bridge), but it didn't open until 1876 and several other bridges in the UK and elsewhere predate it by many years. The Guangji Bridge (https://en.wikipedia.org/wiki/Guangji_Bridge_(Chaozhou)) (1170 CE) is also mentioned but as far as I can see the movable section consists of floating pontoons that can be towed out of the channel.

 * Canals (the Kennet and Avon for one) were using lightweight wooden footbridges first, as vertical axis swinging bridges, rather than their earlier drawbridge form. Brunel's Swivel Bridge in Bristol (see balloon flange girder) has some claim to be the earliest (one of the few Bristol bridges he actually designed), for an iron load-carrying bridge. Armstrong's bridge in Newcastle has never been the first swing bridge, it was the first powered swing bridge. Armstrong's trade and innovative developments were in hydraulic power, not in bridges.

 * Thanks for the info. I knew the Newcastle claim was spurious! I suppose it's impossible to determine the first use of a vertical axis swivel as it was probably invented independently and anonymously in several places.PhilUK (talk) 19:26, 29 October 2016 (UTC)
 * I spent a rather marvellous New Year's Eve in its driving cab once. Andy Dingley (talk) 23:33, 29 October 2016 (UTC)

Maintenance template
Is there a reason to keep a maintenance template on this page? was added eight years ago, when the article did not have any sources. That was changed to about five years ago, when the only references were Google Maps links. It now has 28 references of which only 8 are Google Maps links. Waz8:T-C-E 05:04, 5 November 2016 (UTC)
 * Several of the citations are still Google Maps coordinates. - Denimadept (talk) 05:48, 5 November 2016 (UTC)
 * OK, thanks for the reply. If I can find more definitive sources for those, I will substitute them. Waz8:T-C-E 02:09, 6 November 2016 (UTC)

Bobtail swing bridge
Is there evidence for the assertion that the Columbus Drive Bridge in Tampa, Florida, is a bobtail swing bridge? A definition of "bobtail swing bridge" would be useful to add to the page. I've found two bridges that might be called "bobtail" because they are shorter on one side of the pivot than the other. Is that the definition? The two are (definitively) Z6, and (maybe) the Tyle Mill Lock bridge, as I mentioned on its talk page. Inkwzitv (talk) 19:52, 29 June 2019 (UTC)

Separate list article
I am planning to move the Examples section into the current List of swing bridges article, which currently redirects to that section. While the merits of having a separate list article have been discussed in this RfD, the size of that section seems large enough to justify a separate article, which would be consistent with lists of other bridge types, such as List of bascule bridges, List of covered bridges, etc. Not feeling particularly bold, I figured I'd ask for feedback before I proceed.
