Tsing Ma Bridge
- Year: 1997
- Location: Hong Kong
With an overall length of 2km and a main suspended span of 1,378m, Tsing Ma Bridge is the world’s longest spanning road and rail bridge; with a duel 3-lane highway on the upper deck and a twin track high speed railway (as well as two emergency roadways) on the lower deck. Kvaerner in joint venture with Mitsui and Costain won the £550m contract in 1992 to build the bridge in just five years with structural completion in only 50 months. This was done to budget and programme despite the project’s massive scale, short timeframe and the exposure to typhoon risk.
Cleveland Bridge were responsible for the construction of the superstructure comprising the saddles (3000t), span cables (28,000t), suspension system, suspended deck and approach spans. This was shared with Mitsui in part (50% of fabrication and offsite assembly in joint venture), but Cleveland were responsible for all the construction engineering, most of the superstructure procurement, and for erection on site with up to 800 men. This required a strong head office team for the engineering and world-wide procurement, as well as a substantial site team to ensure successful completion of the project, prior to its opening date on April 27, 1997.
