Bridges
Bridges were added in Update 4, and currently come in two variants, Truss bridge and Cable stayed bridge. They provide a means to connect islands over water, or as an elevated route bypassing a valley below.
Lanes
Bridges can have their lanes changed at any time with no cost. There are 4 types of lanes that can be applied: 1. Left-hand drive 2-way small road (Pickups, Trucks, Small Excavators and Excavators) 2. Right-hand drive 2-way small road 3. 1 lane rail 4. 1 lane electrified rail
There is no lane variant that allows Mega Trucks or Mega Excavators to cross a bridge.
