The Bai Chay Bridge, spanning a strait within sight of Ha Long Bay, Vietnam’s premier World Heritage site, has the world’s longest center span length of 435 m, as a single plane cable-stayed prestressed concrete bridge, with a bridge length of 903 m.
The foundations for the main piers were constructed by the pneumatic caisson method. Form travelers were used for the cast-in-situ box girder erection by the balanced cantilever method. The main pylons, which extend 91,5 m in height above the deck level and which incorporate 28 stay cables and anchorages each side, were constructed using a climbing formwork system.
The design wind speed for the bridge is 50 m/s over a ten-minute averaging period at 50 m above sea level.
The Bai Chay Bridge was opened for traffic in early December 2006. Completion of the bridge will not only enhance tourism to the World Heritage site of Ha Long Bay located close by, but will also improve trade links between Vietnam and Southern China thus encouraging further development within the region
