Officials on both sides of the border continue preparing for Nik Wallenda's high wire walk over the Horseshoe Falls this Friday night.
According to Wallenda's estimates, 120,000 people could turn out for the daredevil's walk across the Horeshoe Falls.
Most of the crowd though will be on the Canadian side, which has the most room, and offers the best sight lines of the wire which will be 180-feet above the lower Niagara River.
Parks Police Major David Page says 25,000 to 30,000 people are expected in and around Goat Island and the City of Niagara Falls.
But Page says the only prime viewing on the U.S. side will be from Terrapin Point.
"We will be screening everybody who will be coming into the area," Page said.
"Terrapin Point will be open to the public until about 5 O'clock. Then, it will be closed to the general public."
Page says federal, state and local law enforcement and first responders have been working on a joint incident plan to ensure public safety.
"I'm not going to get into particular numbers, but we've looked at the whole plan. We've put it together welland we've dedicated a lot of resources to the event."
The Wallenda Walk at Niagara Falls is set to begin at 10:20 Friday night.
