| Abstract: |
As part of the strategic road network in Hong Kong, an express link will connect East Kowloon and the new town of Tseung Kwan O. Part of this link includes an elevated interchange over the sea with seven post- tensioned bridges. The series of balanced cantilever bridges within this marine interchange run in a spaghetti junction manner around the main line viaduct, which comprises two parallel bridges connected at each pier with a cast in-situ diaphragm. This paper presents the project’s unprecedented design challenges, along with the methods used to construct the complex viaducts whilst ensuring a safe construction environment. |
