I don't think there will be a post oil industry, at least not as long as we have roads and cars.

We don't really need as much oil for walking paths, trains, or bike trails, and potholes are a different problem with different solutions for those.

As long as we have cars as we know them, we'll have oil. Road construction require s oil, all of the plastics in cars require oil, trucks require oil, shipping vessels require oil, it's oil all the way down.

It would require a seismic shift in life as we know it to live in a post oil world. Our stockpiles are pretty low (maybe a month in the US).
