Hong Kong-Zhuhai-Macau Link

HZM Link - Mantis island

Developed as part of a small team while working at Dissing+Weitling Architecture in Copenhagen, Denmark.

The Hong Kong-Zhuhai-Macau Link, also known as HZM Link, is a 36km connection between Hong Kong, Zhuhai and Macau across the Zhujiang (Pearl river) estuary. It comprises a multi-span bridge with three large spans, a 5km tunnel and two artificial islands.

I worked as part of the team on all aspects, specifically on developing the 2D and 3D design solutions for the bridges.

The link consists of 70m span viaducts, 110m span viaducts with haunches, a 220m multiple span extra-dozed bridge (Jiuzhou Bridge), a 220m span 2 pylon extra-dozed bridge (Jianghai Bridge) and a single pylon 2×350 m cable-stayed span (Qingzhou Bridge). The goal was to create a consistent architectural design, a family of parts. The aim was an optimal solution in regards to economy, structure and constructability. The architectural qualities are based upon clear, simple and refined features.

The cable-stayed bridge has a split deck solution, while the shape of the box girder is in principle maintained. The tall single pylon is related to the extra-dozed piers and pylons with its curved shape. Brackets below deck provide stability and relate to the pier heads. The pylon has vertical reveals above deck, giving it a characteristic appearance of elegance and lightness. The reveals are finished off with glass and lighting fixtures at the top further adding to the dynamic appearance
and enhancing the night time view.

The proposal includes two alternative designs for the islands, either in the form of an oval or of a triangle with inwards-curved sides. The two islands frame the navigational channel in a harmonious and beautiful way worthy of the proximity to the Chek Lap Kok Airport and Hong Kong.

The larger of the two, the East Island, has been designed as an attractive leisure area. A large, green structure rises from the northern, eastern and southern perimeters of the island and culminates in a large, tall, glazed façade facing the wide promenade/boardwalk on the west side. The structure may house activities such as aquarium/delphinarium, restaurants, cafés, shopping, parking, etc. The island is equipped with piers for tour boats, sail and motor boats.

The islands’ tunnel entrances are equipped with louvres above, providing drivers safety in mediating the transition in light intensity from daylight to artificial light. The theme of the louvers, as folded structures, is carried through in the long slits/folds providing daylight to the underneath leisure facilities.
