Stone x 1 per unit of length
Stone roads can be placed to greatly increase the speed that citizens walk when moving from place to place. Stone roads require builders to use stone to construct each section of the road. Dirt roads can be built with lower expense than stone roads, but they don't come with as high of a speed increase.
After placing roads, builders will work on each section of road, removing rocks, iron ore, and trees that are in the way, and paving the path for citizens to walk on.
Stone roads increase movement speed by 50%.
