Roads are a very important element of every city in Anno. They connect all buildings, serving a few purposes:
- they allow your population to reach their houses and public services
- they allow for goods transportation
- they allow emergency services to fight city incidents
All residences and warehouses have to be connected to the trading post. Production buildings don't need an access to the trading post, as long as they are connected to the warehouse - however, at least this warehouse has to be connected to the trading post.
There are two types of roads: dirt roads and paved roads.
Connects buildings and allows for transportation of goods
The basic type of road, unlocked at the start of the game. Costs 2,5 coins per tile (even though the construction menu indicates that it costs 3 coins). It connects all buildings but their range will be much smaller than in case of paved streets.
Improves street connections and allows for faster transportation of goods
The more advanced type of road, unlocked after reaching either 1 Workers or 1 Obreros. It enhances all street connections by increasing the street range of all public services, production buildings and power plants. The range is increased by roughly 50% (rounded down to the closest integer) in comparison to the range when dirt roads are used. Eventually all roads should be paved to improve street connections and make goods transportation faster.
It costs 12,5 coins and 0,25 bricks per tile. However, the construction menu indicates that it costs 13 coins and 1 brick per tile. In fact, every single tile costs 12,5 coins but the amount of bricks consumed is always rounded up. Building paved streets tiles individually costs 1 brick per each tile; building 2 or 3 tiles at once also consumes 1 ton of bricks. Therefore it is recommended to build a number of tiles that is a multiple of 4, only then you will efficiently use up every ton of brick.
To place a road select it in the construction menu first (or use a shortcut: S for dirt road and Shift+S for paved street). Then click on a tile where you want the road to start and then click on a tile where the road should end. If the starting and ending tile are not in one line, the road will be built in such a way that the distance between both points is the shortest and corners will be placed were needed. If no objects block the path, the road will form two sides of a rectangle. By clicking , or . you can change on which sides of the rectangle the road will be placed. You can build only one tile of road if you click twice on the same tile when placing roads.
The most efficient way of placing roads is to hold Shift when placing them. While holding shift you can click in multiple places to connect them all with the road. In this mode you can build really long roads in any arrangement you want. It is especially useful in case of paved streets, this mode ensures that you use up every ton of bricks as efficiently as possible.
You can cross rivers with roads by building bridges. To construct a bridge the starting tile of your road should be on one side of the river and the ending tile on the other side of the river. Bridges cost additional resources besides regular costs of the road.
Roads can also cross railway without any impact on trains movement. Roads built across the rails don't cost any additional resources. Since update 4, rails can be crossed not only by single one tile wide roads but also double two tiles wide roads.
