How would one go about a bridge that looks roughly like a suspension bridge?

Where the Xs are walls or floors, I guess, and the Rs are ramps.

You can build a ramp on a floor created by a wall below.  You can build a wall one additional tile out as you move upwards.  How could you build *more* than one additional tile out?

Can you build a wall next to a floor, over nothing?  Will I need tons of floor scaffolding to get this done, or do I even have to build up-down stairs up from the bottom?

[Sphalerite]

Yes, a floor will support an adjacent wall constructed over empty space.

In short, you need to have a connection with the ground somewhere, even if that path takes an aerial route for many hundreds of tiles before it reaches ground.

You can even stick a wall on the roof of a large chamber without it falling, I believe.

You'll need some scaffolding. A line of floors alongside the walls you need to build should do the trick.

What you're describing is an arched bridge, though; a suspension bridge is "hanging" from supports with massive cable systems, like the Golden Gate bridge.

A suspension bridge would be a good trick - take some work, building scaffolding and then tearing it down. Quite the project.

s - any construction such as yours simply takes planning, to guarantee that your masons have access to whatever needs to be built.  It's too easy to wall off what you wanted to construct next.

See wiki "tower" for some basics on "how to".

^Also see "cave-ins" to learn just how stable DF structures are.

Will posting an epic bridge inspire you or discourage you?

Well, whatever. See Mountainbanners for an excellent example of a bridge fortress.

For scaffolding, it is easier to build bridges than to build floors.  *Much* easier to deconstruct, as well.

The only downside with using bridges instead of floors is that bridges do not provide support, so be careful of this scenario:

Code: [Select]


bbbbbbb
RXXX123
bbbbbbb

R = ramp
X = wall
b = bridge
1, 2, 3 = designated walls to be built

If 2 or 3 is built first, they will collapse, because there is no support.  This becomes less of an issue if you have a level below (or above) done that can provide the necessary support.

<facepalm>

duh, ya'd think, huh?

Am adding that to wiki, thnx.
