The history of bike paths in the USA
With the development of the bike, experiments with cycling facilities started. Money was available because cycling at this time was mailny practiced by the rich.
More cars meant that the development of a cycling infrastructure almost came to a halt until the 80s of the 20th century.
Because of the increased environmental awareness and the focus on health, cycling in the 21st century got a lot of attention in the USA. Relatively large federal and regional funds are available for the construction of bicycle paths.
