I live in Kansas which has some of the best roads in the country. It's also one of the states with the worst annual temperature swings, which is really bad for roads. You know how we do it? Taxes, and government inspectors, two things which any libertarian finds to be a basic evil. I used to work as one of those state inspectors and now I do the same job in the private sector, if you honestly believe that the private sector is more efficient than the state, then boy do I have some news for you.
