If your city is like mine, there have been many initiatives over the years to improve its bike-friendliness, from painted bike lanes to pathways to separated bike lanes. But if you’re city is really like mine then many of those routes remain islands unto themselves, disconnected from each other and untethered to a more comprehensive plan intended to help cyclists really get around the city. So after exploring these disconnections, I have a theory that there are four different types of disconnections that can be easily fixed to make our cities more bike-friendly.
