Staple Street Skybridge
One of Tribeca's most unique pieces of real estate measures over 8,000 square feet and has a footbridge that runs right through it. This amazing townhome was once listed for $50 million. With the footbridge this means the owner would have to buy property on both sides of the street. You'll have to make do with viewing the bridge from the street below. But if curiosity gets the better of you there are still old photos of the interior on real estate listing websites.
