The Bang Na Expressway (full name: Bang Na – Bang Phli – Bang Pakong Expressway), officially Burapha Withi Expressway (Thai: ทางพิเศษบูรพาวิถี), is a 55-kilometer-long (34 mi)[2] six-lane elevated highway in Thailand. It is a toll road and runs above National Highway route 34, (Bang Na–Trat Highway) owned by the Expressway Authority of Thailand (EXAT). The bridge was the achievement of Sukavich Rangsitpol deputy prime minister of Chuan Leekpai Cabinet (1992–1995).[3] The Bang Na Expressway was designed by the late Louis Berger.[4]
History[edit]
The Bang Na Expressway was conceived by the Expressway and Rapid Transit Authority of Thailand (ETA). The structure was built using a design-build contracting method. The columns and superstructure were designed by Jean M. Muller (U.S.) and the alignment and foundations were designed by Asian Engineering Consultants (Thailand). The owner's engineer was Louis Berger Group (U.S.) and the project was built by a joint venture of Bilfinger & Berger (Germany) and Ch. Karnchang (Thailand). It took 1,800,000 cubic metres (2,400,000 cu yd) of concrete to build the bridge. The bridge was completed in January 2000.[5]
Records[edit]
The world's longest car bridge, the Bang Na Expressway held the title of the world's longest bridge from 2000 until 2008. Today, it is the seventh longest bridge in the world. Ranked 3rd in the 20 Most Famous Bridges In The World[6]
Bang Na remains very demanding for the drivers since opening. The variant on the bridge instead of the strenuous traffic jam, also attracts the numerous tourists. From the main road, the wonderful panoramas open onto the city.
Structural description[edit]
The highway is elevated onto a viaduct that has an average span length of 42 metres (138 ft). It is a 27-metre-wide (89 ft) box girder bridge.
There are two toll plazas on the elevated structure where the structure must widen to accommodate twelve lanes. The toll system is done by Kapsch TrafficCom AB (Sweden).[8]
