Road

Roads speed land unit movement. Land units moving along a road can move three times faster than normal. Roads also increase mine production in rocky squares.

Background
Most of Planet's ground vehicles were capable of off-road travel, but movement along a paved road was still more efficient. Indeed, the first phase of human development in a region was usually the construction of a road. Road crews were the romantic epitome of the terraformer's lifestyle, working for months or years out in the wilderness, with little support from home.
