Road transport might be cheaper at first, but ongoing construction and maintenance costs do add up in a hurry, and as traffic builds the amount of money that has to be spent scales up pretty quickly.
A lot of the savings roads enjoy versus things like rail is that maintenance is perpetually deferred. A private railway has to ensure the tracks are all maintained to a very high standard, to do anything else is to invite disaster, but a local municipality can let its roads go to hell without much in the way of consequences.
