The water source from the top of the mountain will try to use the road as its quickest way down, so they build drainage pipes to prevent these roads from flooding! -linda

The drainage pipes are to prevent the road surface cracking by keeping the ground near the road dry. When the ground underneath the road gets wet, the road could sink, kind of like when you walk in a swamp. If only part of the road sinks and the rest stays in the same place, the road could crack where the sunken portion of the road meets the part that hasn't sunk.
You need traffic engineers to design road/highway systems that are effective and safe.
Intended use and design speed of highway
I am not sure I need to know too. Maybe because of a tornado or it is not safe to do construction on it and it is easier to do it on a highway.
when multimedia owners gain information about the worth of their product they need to sell their product so they sell their product online as distributed resources on the data highway(like a road highway toll) where the customer or user needs to pay money in order to use the service or acquire the content. various elements like videos, sound, images an other interactive contents are shared over the highway.
I'm assuming it's because the water source at the top of the mountain will try to use the road as its quickest way down, so they build drainage pipes so stop the road from flooding
