Nancy Nowacek

From her back window on Columbia Street in Brooklyn, artist Nancy Nowacek could see Governors Island and Buttermilk Channel (the strait connecting Brooklyn to the island), and it seemed incredibly close. In fact, it's the equivalent of only about four city blocks away. So since 2012, Nowacek has been working on her vision of building Citizen Bridge over New York Harbor, a floating modular pedestrian bridge over the 1,400-foot span from Red Hook to Governor's Island. In what is currently planned as a one-day-only event, she sees Citizen Bridge as a completely new way to experience New York City harbor, rather than seeing it from the shore, from a bridge above, or from a boat. As noted by Mental Floss, Nowacek has turned to Kickstarter to raise money for a pilot phase. The project's goal of $25,000 would fund a proof-of-concept, which is the final phase before launching for real.  So far, they've prototyped seven bridge designs in full-scale sections.
