State Route 91, the Riverside Freeway in California, was fully financed by municipal bonds. Munis have caught on with many countries, including countries in transition. Last but not least, private enterprises are allowed to own their own infrastructure. In many countries, construction licences are conditioned on participation in infrastructure costs. Macedonia's infrastructure is decrepit.
Maintenance is bad.
Planning is absent. Corruption is rampant. The only hope is to remove as much as we can from the process of planning and constructing transport infrastructure from the hands of the state. Maybe this will even attract the billion dollars under our mattresses and carpets.
