Known as Raffles City Chongqing’s crowning glory and the development’s “horizontal skyscraper”, The Crystal is an enclosed sky bridge nestled above four 250-m-tall skyscrapers and links two adjacent towers by cantilevered bridges. Measuring 300 m in length, 32.5 m in width and 26.5 m in height, it is the world’s highest sky bridge linking the most number of towers.
Envisaged as the centre of civic activities where locals and visitors from around the world converge in Chongqing, The Crystal houses a rich array of amenities, including a viewing gallery, lush gardens, an infinity pool and restaurants. When darkness falls, it transforms into a giant light beam, illuminating the night sky with a pulsating light show. To ensure the public’s year-round enjoyment of The Crystal’s facilities, design provisions such as air-conditioning, have also been catered for.
The Crystal is made up of a continuous steel structure weighing 12,000 tons and enclosed with a ring comprising about 3,000 pieces of glass panels and close to 5,000 aluminium panels. To erect efficiently, the steel structure is first divided into nine segments – four segments that are built in-situ above the four towers; three middle segments suspended between the four towers that are prefabricated on ground and hoisted into place by hydraulic strand jacks; and two cantilever segments that are assembled in short sections from the two ends of the rightmost and leftmost towers. Hoisting the three middle steel segments of The Crystal – each weighing up to 1,100 tons – to the designated height of 250 m marks a world first.
Fun facts
1) At 300 m long, The Crystal is longer than Singapore’s tallest building laid on its side. This is also more than three times the height of the Statue of Liberty in the United States, which measures 93 m, laid on its side.
2) The Crystal’s continuous steel structure weighing 12,000 tons is equivalent to the total weight of France’s Eiffel Tower.
3) The Crystal will be home to close to 120 trees, which will measure about 9 m in height when they have matured.
4) The Crystal houses two pools – a 50 m x 8 m main pool and an adjoining 10 m x 8 m children’s pool.
