The Crystal, Chongqing: China's new 'horizontal skyscraper' is nearly complete

Billed as the world's highest sky bridge, China's latest mega-structure - the eighth and final skyscraper of Raffles City Chongqing - has moved a step closer to completion.

Six of the enormous structures are linked by The Crystal - a 250-metre high "horizontal skyscraper".

Measuring 300m in length, 32.5m in width and 26.5 m in height, it is the world's highest sky bridge linking the most number of towers and was designed by world-renowned architect Moshe Safdie.

Lucas Loh, President of CapitaLand Group, said the topping out is a milestone for the $US3.8 billion project.

"After six years of construction using state-of-the-art engineering technologies, we are proud to present in Raffles City Chongqing an iconic architectural form resembling a powerful sail surging forward on the historic Chaotianmen site."

Occupying 9.2 hectares of site area, Raffles City Chongqing brings together a 235,000 square metre shopping mall, 150,000-sqm of office space, and 1400 residential apartments.

Chongqing is at the intersection of the Yangtze and Jialing rivers.
