Bridges

Bridges take your roads across obstacles. There are two kinds: the bridge across the canyon and the bridge over another road.

Across the canyon

The canyon with the blue lava river runs right through the north. Drag a road straight across it and it turns into a bridge on its own. It rises at the edge and spans the water in a flat arch. You build it like any other road and pay the normal price per tile.

Over another road

If your new road fully crosses an existing one, you can choose bridge instead of junction. It then crosses over without an exit and both roads keep flowing without traffic lights. If several roads lie close together, one shared deck spans all of them.

• The bridge needs room for its ramps on both sides. If the road is too short, the preview tells you.
• No other road may join at the ramps, there are no junctions on a slope. Behind the ramp it works again.
• It costs as much as a normal road.
• If a junction does not fit at a spot but a bridge does, the preview turns orange and only offers the bridge.

At the highway a cloverleaf interchange normally appears, and its bridge brings the ramps along (Highway Interchange). If you explicitly choose bridge there, your road crosses the highway as an overpass without ramps.

Bridges and traffic jams

A single bridge across the canyon quickly becomes a bottleneck: everyone who wants to get to the other side has to use it. Plan a second bridge or a wide road for the most important crossing early (Traffic and Jams).
