Bridge to the Future

The Chao Phraya River Bridge, slated for completion in 2007, will be the longest bridge in Thailand. This article describes the engineering and design of this bridge. The cable-stayed bridge will have a main span of 500 m and two side spans of 220.5 m. Four main design goals were established for the bridge: be long lasting and easily maintained, enhance the city architecturally, be economical and incorporate the maximum amount of local materials, and not disrupt marine traffic during construction. The resulting design is a 36.7 m wide superstructure that will carry four traffic lanes in each direction and provide 50.5 m of vertical clearance for marine traffic. The superstructure is a steel frame composite with a concrete deck. The bridge's two A-shaped towers straddle the 500 m main span and are stylized representations of the traditional Thai greeting of hands steepled together. The bridge was designed for truck loads 30% higher than those set forth by AASHTO Standard Specifications for Highway Bridges. Construction of the bridge began in August 2004.
