Bang Na Expressway

The Bang Na Expressway (full name: Bang Na – Bang Phli – Bang Pakong Expressway), officially Burapha Withi Expressway (ทางพิเศษบูรพาวิถี, lit. Road to the East), is a 55 km six-lane elevated highway in Thailand. It is a toll road running above National Highway 34 (Debaratna Road, Bang Na–Trat Road) and is owned by the Expressway Authority of Thailand (EXAT).

History
The Bang Na Expressway was conceived by the Expressway and Rapid Transit Authority of Thailand (ETA) and Sukavich Rangsitpol, deputy prime minister of Chuan Leekpai Cabinet (1992–1995). 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 designer and engineer was the late Louis Berger of the Louis Berger Group and the project was built by a joint venture of Bilfinger & Berger (Germany) and Ch. Karnchang (Thailand). It took 1800000 m3 of concrete to build the bridge. The bridge was completed in January 2000

The expressway was opened in its entirety on 7 February 2000.

Structural description
The highway is elevated onto a viaduct that has an average span length of 42 m. It is a 27 m 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).

Records
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

"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."
