Hyder Consulting has completed the concept and preliminary design for a glass-clad bridge over the Haihe River in the Chinese city of Tianjin. The concept for the 192m-span bridge - which was developed in conjunction with architect Ronald Yee - incorporates steel pylons clad in glass panels. The cable-stayed structure's two main and two secondary pylons are arranged in a radial maner. Bearings at the base of the pylons allow rotation to minimise moments in the foundations, deck and pylons. "The design is unique in geometry and articulation with no resemblance to any other road bridge that we have seen," said Hyder's project director, Francis Kung.
