Plans to replace two 115-year-old pedestrian bridges could leave the American Falls dry for up to nine months while water from the Niagara River is diverted over the Canadian Horseshoe Falls. US Army Engineers once before shut off flow to the American side to examine the stability of the area. New York State Parks officials says it won’t happen before 2019 and all funding is in place.
