Why do states basically hire people to dig ditches and then hire people to fill them back in?

They should have the up and downhill different grades

This is really shitty bait.

Explain how OP is wrong. I don't know either why they would do that. Please explain like I am 5.

What is a gradient?

terracing the road rather than going with a straight incline isn't really a drainage-mitigation measure
it was most likely to make the road slope more gradual

you'd get the same flow coming down into the valley in a storm event; terracing only makes the water sit there rather than flow down (i.e why it's useful for agriculture/rice paddies) but not what you want for a road

you'd build dykes besides the roadside ditches if you were that concerned about flooding

in most cases they'd just elevate the road high enough

if you go straight up, you the steep downward hill becomes a massive safety hazard and a death wish if bad conditions arise.

Nice

that guy said it all

>we're going to drive a fully loaded 80,000lbs big rig straight up this here mountain, boys!

sterilize yourself and do humanity a favor

The drainage pipes run under it, leaf.
