magine having a bridge all to yourself, connecting two apartments in the sky above Manhattan. This rare luxury is now available for $2.75 million at 52 E. 78th St., an Upper East Side penthouse listing that's part of a historic duplex.

    The pièce de résistance is the landmarked steel-and-concrete bridge, which has been updated with a glass ceiling and under-lit glass floor. The bridge connects to three private balconies, a charming rooftop garden with a white picket fence, and a dining area. This unique feature makes for unforgettable dinner party conversation.

    The duplex boasts three bedrooms, 2.5 baths, and a chef's kitchen. Its history dates back to Finch College, an elite liberal arts college for women, where the bridge connected the school to its dormitory. The seller, who requested anonymity, negotiated with the building to transform the bridge roof into a stunning garden.

    The listing has other cool touches, including a statement staircase and mod-looking kitchen. The main bedroom suite features built-in storage space, while the tony exterior of 52 E. 78th St. offers easy access to the outdoors. A floating staircase leads to an upper level with two bedrooms, a bath, and the roof garden.

    The seller purchased the property for $735,000 and invested in a two-year, million-dollar renovation led by the structural engineer of the Metropolitan Museum of Art. The listing brokers are Mike Barit and Justin Rubinstein of Compass.
