Explanation:
The primary function of all the roads the Romans built was to link their military garrisons.Advantages to trade and communications were entirely a by product.
All the roads were built in a straight line,through or over all natural obstacles.This meant the legions would have the shortest distance to march between any 2 given points.Each road was also wide enough for 2 legions to pass each other,in opposite directions, in normal marching order.This meant each road could be used to send troops to different places at the same time.
