Aesthetics. Functionality. Price. Those were the key parameters in the design competition for a new major link connecting the cities of Shenzhen and Zhongshan in Guandong province in sourthern China. The link will be 24 kilometre long and consist of two artificial islands, two bridges and the world’s widest immersed tunnel with eight traffic lanes in dual directions and with a capacity of 90.000 cars per day. The fixed link will act as a landmark for the entire region, as well as further the economic development of the region.
The competition was initiated by The Advanced Work Office for the Shen-Zhong Link Project in September 2015. The team consisting of DISSING+WEITLING architecture and engineering consulting group COWI, both firms based in Denmark, have now been announced the winner. Among other projects, DISSING+WEITLING architecture and COWI, are responsible for the design of the famous Danish 18 kilometre long crossing of the Great Belt linking the eastern and western parts of Denmark. Both companies were also deeply involved in the Öresund Bridge linking Copenhagen with Malmoe as well as the Hong Kong – Zhuhai – Macao link currently under construction in China.
While being a functional infrastructure, the ShenZhong Link will also be a beautiful iconic structure. All components in the link relate optimally to one another in terms of purpose, scale and proportions.
The bridges accentuate the qualities of grace and elegance inherent to the carefully articulated suspension bridge. Whereas the cable curvatures of a suspension bridge is a common recognized feature, the towers are the bridge component, which truly provides the bridge with its aesthetic identity and defines the image of the bridge in the eyes and minds of those who experience it either by car, plane or from the seaside. The slenderness of the towers will be exceptional and unique to the world of bridge architecture because of the height and length of the single tower suspension bridges.
The piers of approach spans have triangulated split head with an articulated shape that will gracefully hold the deck and give it an almost floating expression. Defining the characteristic of the bridge’s design, they will contribute to the landmark status of the bridge.
The tunnel will mark a world-record as the widest immersed tunnel with the widest road bores ever built. The proposed concept is a post-tensioned segmental tunnel consisting of 31 elements in total, typical element being 185 metres long and the widest being up to 70 m wide. The width of the road bore varies from 19 m to 38 m.
From around the bay, the Island will be a visible, yet not an intrusive feature. It will become a natural end to the bridge as a “dot” in a sentence, a pause, a transition to something different, something new. When approaching the Island from the West, the “arrow” with its white concrete tactile surface, will give a remarkable visual expression. Its sharp and well-defined profile will be a contrast to the organic shape of the mountains in the background. The Island presents itself as a theatre stage and the strong, balanced structure will give a sense of secureness and ease, as the driver approaches the Island-Tunnel. On the Island, there will be different mitigations, such as windmills, solar power and water treatment plants as well as conference, office and restaurant facilities. It will be platform for China to exhibit their increasing involvement in a cleaner and more sustainable world.
"The design is a synthesis of the requirements and constraints of the Pearl River's estuary where shallow and calm water has been a great inspiration calling for elegance and harmony. The island is designed to minimize blocking effect in the water, the shape similar to a classic Chinese kite and combined with the bridges, the entire link can visualise a kite with tail elegantly landing on the water," says Poul Ove Jensen, Director of Bridges and Architect MAA at DISSING+WEITLING architecture.
In their comments the jury emphasized the harmony expressed in the winning design:
"The design philosophy of the concept is advanced. The overall design of the link is magnificent, elegant and concise. The design of main bridges, the approach bridges and the artificial islands is integrated, the holistic impression and iconic landmark of the link is prominent, the whole link is in harmony with the surrounding environment, the Y shaped pier shaft of approach bridges give a very strong sense of rhythm."
