My G-G-Grandfather built a road in the howling wilderness of what is now West Virginia in the 1820s that has now become a state highway. He didn't have any government help, but he did have help from family members building it.
Almost every major road and highway in the area where I live in the West was once a privately built toll or wagon road, all originally built without any kind of government help.
Almost every road in your area was not only built with private capital, they were operated under licenses that required the owner to cede the road back to the government after a period of time, an open-eyed deal but a total confiscation of the asset. Some of them lost their shirts on the roads but made out on the homesteads they settled along the way.

That's like saying, "The air was plenty clean around these parts before there even was an EPA." You hear several of the standard liberal variants of "Damn your logic."
