Using them to control [[flow|fluids]] can save a ton of mechanisms and time, especially when the fluid in question is free-flowing and not pressurized (by {{L|pump}}, {{L|river}} or hydrostatic anything) and needs a wide tunnel. |

They are first designed by an {{L|architect}}, then require a specialist worker for the material used (e.g. a {{L|mason}} for a stone bridge). The size of the bridge can be altered with {{k|u}}{{k|m}}{{k|k}}{{k|h}} while placing it, up to a maximum size of 10 squares in each direction. The bridge must be anchored to a solid surface on at least one edge. Before placing the bridge ensure that the bridge raises in the direction you want it to using {{k|w}}{{k|a}}{{k|d}}{{k|x}} or retracts using {{k|s}}. |

If a bridge is set to retract when the lever is pulled, the bridge essentially disappears dropping anything (friend, foe, or object) on the bridge onto whatever is underneath.

The resulting wall is always one z-level tall, regardless of the length of the bridge. The wall acts as if it was {{L|construction|constructed}}, rendering it invulnerable to {{L|building destroyer}}s. {{Verify}} The bridge also "moves" to this position very fast, firing anything on the bridge into the air. The key advantage to raising bridges is the creation of a wall when the bridge is raised. This can be used to block fortress entrances/corridors. Using 2 bridges at opposite ends of a corridor creates a very large and simple trap by walling in enemies. Or... Smashing them to tiny bits if placed to raise facing eachother, with no space inbetween. For added effect, place {{L|pressure plates}} on both ends to raise the bridge when stepped on, to fling them, if there is a {{L|floor}} directly above, they will be stunned, (If there is a floor beneath the bridge) and if nobody is on the pressure plate, they have to be lucky to not be smashed on the floor when the bridges come down. (If there is no floor beneath the bridge) they will fall, sometimes into something {{L|water|very,}} {{L|magma|very}} {{L|megabeast|bad.}} |
Walls cannot be built along map edges. Because bridges can be built along map edges and then raised to act as walls, they can be used to control where enemies spawn on the map. | Walls cannot be built along map edges.

Even fluids get destroyed (this is especially useful considering lack of chasms in the new version). However, lowering a drawbridge onto a sufficiently large creature (such as a {{L|forgotten beast}}) simply destroys the bridge. |

This weight limit is not cumulative - a bridge will still retract if a hundred goblins are standing on it, but a single rutherer accompanying those goblins will prevent the bridge from operating. Attempting to lower a drawbridge onto such a creature (in order to {{L|Dwarven atom smasher|atom-smash}} it) will cause the bridge itself to deconstruct. |

The retracting bridge on the higher z-level is used not to permit access across a channel, but instead to block access to a ramp. Thus, a single lever can be attached to both the drawbridge and the retracting bridge, preventing airlock vulnerabilities due to lever timing. With a suitably long distance between the two bridges, the lever can be placed between the two, permitting easy movement of individual dwarves between isolated zones, via lever profiles. | The retracting bridge on the higher z-level is used not to permit access across a channel, but instead to block access to a ramp.
