PROJECT DESCRIPTION

The Second Penang Bridge is a 24 km sea crossing linking the Penang Island and the Malaysia Peninsula. The Bridge is the longest sea crossing in Southeast Asia and consists of an in situ concrete cable-stayed bridge 475 m long and precast segmental concrete marine viaducts in 55 m span modules, founded on extensive marine piling.  In the shallow water zones, 1.0 m diameter concrete spun piles were used but in deeper water 1.6 m diameter tubular steel pipe piles with discrete pile caps were used, necessitating the most extensive use of cathodic protection in Southeast Asia.

Judge's comment:

The judges were impressed by the response to the engineering challenge presented by the sheer size of the crossing.  In particular, the cable stayed bridge over the main navigation channel is founded on bored piles socketted into bed rock at depths over 100 m below water necessitating bored piles with lengths of up to 127 m.
