Hong Kong Stonecutters Bridge open for operation

The world’s second longest spanning cable-stayed bridge, Stonecutters Bridge, opened to operation this week in Hong Kong.

The bridge’s key design features include a 1,018m long steel main span supported by two 290m tall concrete and stainless steel towers and a 53m-wide deck split into two streamlined boxes connected by cross girders. It is one of the two cable-stayed bridges with a span in excess of 1,000m.

Consultant Arup provided civil, structural, M&E, geotechnical traffic, wind, marine and durability detailed engineering design and construction supervision on the project.

The innovative bridge has a vertical clearance of 73.5m over the navigation channel. Great control was required during casting of concrete elements and prefabrication and assembly of large-scale steel elements that make up the deck and have to be fitted together, to ensure accurate dimensional control.

“The most challenging part is the coordination between the various elements of the bridge. All parts have to fit together, which means close co-ordination between on-site and off-site construction.”

The bridge straddles the Rambler Channel at the entrance to the Kwai Chung container terminals, providing a landmark gateway to one of the world’s most vibrant trade centres. It will facilitate the logistics industry development and will play an important role in coping with growing traffic between Northeast New Territories, Kowloon and western part of Hong Kong.

Arup East Asia Chairman LM Lui said: “The most challenging part is the coordination between the various elements of the bridge. All parts have to fit together, which means close co-ordination between the temporary and permanent works and between on-site and off-site construction.”

The 1.6km long crossing will be the centrepiece of the new Route 8 strategic link, a 7.6km long, dual three-lane expressway linking Cheung Sha Wan and Tsing Yi Island. The route will improve access between the International Airport and the urban areas of West Kowloon, as well as providing enhanced links to the container port, one of the busiest in the world.
