This makes a lot of sense actually, motorized vehicles have a lot more trouble with slopes than people (and pack animals) do.
Also, in Roman times road construction had to be done entirely by hand and out of stone. Modern "pouring" of roads with asphalt or concrete was not yet a thing back then, so it makes sense to try and limit the hard work of construction as much as possible.
- astine 6y agoYeah they needed a lot of big paving stones which I'm guessing were a relatively scarce resource, Not to mention that road building was a military practice done by the army to facility the moving of large armies. Travel time took priority.
- kevin_thibedeau 6y agoBuilding roads on the side of a slope requires a lot more excavation to create a level road bed than going up and over.
- ableal 6y agoNow that we have electric vehicles with torque from 0 rpm, and regenerative braking, we can go back to straight roads ... (Just the other day I was observing that zigzag roads up/down mountains were probably a consequence of engines unable to apply power at very low speeds and friction brakes.)
