This article describes the design and construction of the recently completed duplicate Tsing Yi South Bridge in Hong Kong, which links Tsing Yi island with Kwai Chung on the mainland. Nine 640m twin spans were constructed, together with five approach viaducts and a vehicle underpass. Other works included slope cutting, dredging and reclamation, piling and earthworks, stormwater culverts, sewer outfalls, other drainage, utilities, and landscaping. The design has several innovative features. Each pier was designed as a pair of twin-leaf walls monolithic with the deck. Fully external post-tensioning was installed within the deck, to facilitate monitoring for corrosion, and removing and replacing prestressing cables, without damaging the bridge. Costs were saved by eliminating mechanical bearings and using the cast in-situ balanced cantilever technique for the two main crossing viaducts. 380 bored piles were installed for the pier foWldations. Several measures, including noise barriers along adjoining roads, were used to minimise the bridge's environmental impact from traffic usage. Work on the bridge construction began in January 1996 and was completed in mid-1999. It included the construction of six 122m spans, each consisting of 27 segments of in-situ balanced cantilevered decks.
