Editing Amazing Deliveries (section)

===Rough Going===

In the past, paved roads and rail lines connected the communities. Today, if two Dome Cities are close enough to each other, they may build an underground tunnel to connect each other. Otherwise, maintaining roads between settlements is not seen as cost effective. Surface conditions would cause constant wear and tear, and need of maintenance, and work crews would risk exposure. What roads exist are mainly trails left by Deliverer rigs. Where traffic is heavy, this results in a packed trail, equivalent of a dirt road. On less used routes, the rigs are practically driving off road.

Deliverer rigs are built for that though, and settlements are not normally built in inaccessible locations – and when they are, they have a depot nearby. The routes may be circuitous to avoid terrain obstacles, but in most cases a way to the destination exists.
