Aqueduct

For the road vehicle/train version, see Bridges.

Aqueducts are the ship version of bridges. They look like a bridge, but is filled with water. Aqueducts are more expensive than cannal tiles, and should only be built when necessary.

How to Build
Unlike bridges, aqueducts must be built on sloped tiles of the same heights. They also won't be built on tile that need support (e.g. diagonal slopes) To build, open the waterways construction button on the menu bar. click the aqueduct button and go to the start of the bridge. Click and drag to the end of the cactus and release. The aqueduct is now there!

Just note that this button won't appear in any version before 0.7.0.

Strategies
Aqueducts can help ships cross inland valleys and mountains. If the land you want to cross a long area of lower land, it is not worth it to build aqueducts; just use canals and locks to cross it. Try to make little mistakes or changes to aqueduct paths, as they use a lot of money to build and destroy.
