From North Country Public Radio:
Parks officials in New York are planning a project of historic significance: temporarily shutting off the American Falls. That will dramatically alter a natural wonder that attracts millions of tourists from around the world.
The Niagara Falls State Park project is designed to replace two pedestrian bridges that are over 100 years old. Those bridges connect the main section of the park to Goat Island, which splits the Niagara River into two falls, one in Canada and the other in the U.S.
Shutting off the flow of the river and the falls will give construction workers access to the bridge supports.
