Talk:Drawbridge

message: Bascule bridge: a type of bridge with a pivoting section that is raised and lowered using counterweights.  How does a drawbridge differ?
:The term drawbridge is often used for any type of movable bridge. --SPUI (talk | don't use sorted stub templates!) 00:34, 26 December 2005 (UTC)
replies: text: If I had to define it I would say that a drawbridge is lifted by chains or cables. A bascule bridge balances around a pivot, with any counterweights fixed to the bridge deck (eg on beams projecting beyond the pivot). Very few drawbridges don't have counterweights, so the terms are not mutually exclusive: many drawbridges are also bascule bridges. Put the same mecahnism on a castle and you would call it a drawbridge; put it over a river crossing and it would be called a bascule bridge. It's arguable that the parts of the Drawbridge#Road, rail and canal article covering (rather badly) transport drawbridges should be combined with bascule bridge leaving the castle stuff to an article on its own; the two don't have much in common other than some fairly obvious engineering.

message: While reading the book Math and the Mona Lisa: the Art and Science of Leonardo da Vinci by Bulent Atalay I stumbled upon the following text
:Among the designs that fill the notebooks one can see that he prefigured, among other devices, the bicycle, the automobile, ...the collapsble bridge...
I was wondering what is meant by collapsible bridge. At first I thought it was the usual drawbridge, but I guess drawbridge was used well before da Vinci's time (15th century). --Kompik 15:03, 3 February 2007 (UTC)

message: I just removed the following sentence from Road and rail, which was added on 20 May 2008 by Tabletop :
:A vertical lift drawbridge at Mossdale in California was the actual final link in the first transcontinental railway and was opened a few months later than the Golden Spike ceremony at Promentory.
There were several reasons.
# The actual final link in the First Transcontinental Railroad was the bridge between Omaha and Council Bluffs, completed in 1872 (see First Transcontinental Railroad#Railroad developments). The Mossdale Crossing was built sometime in the latter half of 1869 (our article claims November, but  says the first train crossed on 8 September 1869).
# I can find no sources, and none were given, that confirm that this bridge was a drawbridge.
# It seems likely that the original bridge is being confused with a later bridge built at the site in 1942 ( says that nothing remains of the original bridge;  says the current railroad bridge, which is a drawbridge, has a plate bearing the date 1942).
Of course, I could very well be mistaken, in which case the sentence should be readded (with supporting references, of course). —Bkell (talk) 13:49, 19 August 2008 (UTC)

message: Does anyone have a view on the inclusion of the animation in the lead? On the one hand, it works, and clearly illustrates what a drawbridge is. On the other, it seems a bit trivial and inconsistent with the usual style of articles. Cyclopaedic (talk) 12:03, 21 September 2009 (UTC)

message: Re: the discussion above: if in British English drawbridge has this narrow meaning -  I'm an American who spent what adds up to about 2 years of my life in England and was unaware of this - fine, but the article should at least discuss this difference between British and American English, and there should be something much more than a "see also" to connect to other related articles. Somewhere there needs to be a central article on bridges that open. Is there a British English term for that? If so, I'm perfectly glad to see that term as the title of that article. If not, then that article should be at this name. - Jmabel | Talk 23:59, 8 September 2011 (UTC)
replies: text: Do you mean bascule bridges which are already mentioned? Nev1 (talk) 00:24, 9 September 2011 (UTC)
replies: text:  Bascule bridge is also too narrow for what I have in mind. We need an overview article about all bridges that open. It doesn't include bridges that open by rotating horizontally, or by lifting vertically (as against hinging from one end), and probably some other configurations I'm not thinking of offhand. (I've heard of bridges that actually submerge to let a boat through, but I've never seen one. I think there may also be some that withdraw horizontally onto part of their own deck. Etc.) - Jmabel | Talk 16:48, 11 September 2011 (UTC)
replies: text:  Movable bridge is a possibility, see www.movablebridges.org.uk. Paravane (talk) 17:19, 11 September 2011 (UTC)
replies: text: Sounds plausible. I'd agree that a "drawbridge" is a narrower term and that a drawbridge article needs to focus down on that meaning. Hchc2009 (talk) 17:36, 11 September 2011 (UTC)
replies: text:  I see we have Moveable bridge; I've added a hatnote here since, in the US, any movable bridge is a drawbridge. Also, by the way, several [two] of the images illustrating the present drawbridge article appear to be bascule bridges, which is very confusing if the intent is an article based on the narrow meaning of the term. - Jmabel | Talk 01:10, 13 September 2011 (UTC)
