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)

I think there is probably a lot more to be said about:

• drawbridges as found in castles, or about
• the general mechanical mechanism that a drawbridge uses.

Each of these I think would fit on this page, but are certainly different from "bascule bridge" as a type of bridge across a river. I think the problem is that this page just needs expansion. Brusselsshrek 15:07, 17 February 2006 (UTC)

A drawbridge is lifted bij cables, the couterweigt is not in line with the road, as are bascule bridges. There's a big difference. T Houdijk 21:07, 12 April 2006 (UTC)

The problem is that drawbridge is both a specific kind of bridge (as discussed above)... and a general term that is, possibly incorrectly, used to describe other types of "lifting" or "opening" bridges (including bascule bridges) - perhaps a subtlety between English English and American English. The drawbrige article simply needs to be expanded to accomodate this... For instance information about drawbridges built to cross castle moats. 69.140.65.251 15:37, 14 May 2006 (UTC)

As the discussion appears stagnent, I am removing the merge tag, but adding a stub note. - Leonard G. 17:03, 11 July 2006 (UTC)

[edit] Da Vinci

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)
