I know that asking you to Google things is maybe a lot, but isn't the answer pretty obvious if you think about it for more than five seconds?
Roads are made out of what would otherwise be a waste product from refining oil, mixed with dirt. If you just leave it alone, it will basically just sit there.
Rails are made out of steel, which is both expensive and rusts. Tolerances have to be tight. And if you fuck about with maintenance in rail, you get a train derailment.
Idk why you got down voted. It makes sense to me!
No, it's because your answer is overly simplistic. We don't build one lane roads, we tend to build 3 or 4 in each direction, at least in cities.
Also, leave a road alone, it does not just sit there. In cold climates you get frost heaves, in hot climates asphalt is never truly "solid" so it gets ruts... water causes damage, plants grow through it...
Add in some of the other responses and we have a more complete picture. I'm not convinced. At best it might be a wash.
*edit* just realized you're not the same person, sorry. My point still stands though.
