It’s the cherry on top of New York’s tallest building.

Final plans for the observation deck atop the new 1 World Trade Center tower are expected to be approved tomorrow – a remarkable milestone for the rebirth of Ground Zero.

Renderings show the three-story deck will give visitors an interactive experience that does everything from trace New York City’s history to provide dining with a window onto New York and New Jersey.

Five elevators will take visitors from the ground to the deck in a speedy 60 seconds once the area opens in 2015. Construction of the deck is going to cost the operator $62 million. Admission rates and hours have not been set yet.
