High-wire performer Nik Wallenda will walk a tightrope over Niagara Falls on June 15.


Wallenda, 33, a seventh-generation member of the famed "Flying Wallendas" family of circus performers, is set to walk a 2-inch cable strung 1,800 feet across Niagara Falls gorge. It's the first such tight rope feat between the United States and Canada in more than a century.


The walk is expected to take 30 to 40 minutes and the cable will be 150 feet above the falls that span two countries.


A long-standing ban on such stunts in and around Niagara Falls has meant that no one has attempted a high-wire walk there in more than 100 years. Gaining permission for the June 15 walk required almost two years of lobbying by Wallenda and politicians in upstate New York who hope the spectacle will translate into tourism dollars.
