"How did the Dutch get their cycling infrastructure?
This question keeps coming back because it is of course relevant to people who want what the Dutch have.
Road building traditions go back a long way and they are influenced by many factors. But the way Dutch streets and roads are built today is largely the result of deliberate political decisions in the 1970s to turn away from the car centric policies of the prosperous post war era. Changed ideas about mobility, safer and more livable cities and about the environment led to a new type of streets in the Netherlands."
