There's still some fune tuning to be done, but the "Wallenda wire" is now in place.
Crews have completed the task of stringing the line from the American side of Niagara Falls to Table Rock on the Canadian side.
For safety reasons, the tension can't be adjusted until the Maid of the Mist tour boats shut down for the day.
120 thousand spectators are expected to gather on either side of the border on Friday night, to watch daredevil Nik Wallenda perform his 45 minute walk. He's expected to start at about 10:20.
Hundreds will get the opportunity to meet Wallenda in advance , as he takes part in a pair of hour long meet and greets at Table Rock on Wednesday and Thursday afternoon.
