State officials are holding a public hearing this week to discuss plans for replacing 115-year-old bridges linking the mainland to islands near the brink of Niagara Falls. To do so, they might reduce the flow on the American side of the falls by building a temporary structure to redirect Niagara River water to the Canadian side. (AP Photo/David Duprey, File)
