This is what bicycle infrastructure could be:

Copenhagen has just opened the first stretch of bicycle “superhighways” (not sure I like defaulting to the language of autodum but whatever) — covered the launch and provides a lovely pictorial of the infrastructure supporst that lead feed into the new route. Note things like the trains and other bike tracks are pre-existing so they do not service the new route specifically, but rather the new route is a rationalization of an existing cycling infrastructure. – Bicycle Culture by Design: Launching Copenhagens Bicycle Superhighways
