Before the four "New York City Waterfalls" began gushing along the East River this June, DOT marked a bike route passing by each installation and released a guide to go with it. In this Streetfilm Elizabeth Press shows us a recent bike tour of the falls, led by DOT commish Janette Sadik-Khan. Special bonus feature: commentary from "Waterfalls" artist Olafur Eliasson about his work.
