The Bang Na Expressway (full name: Bang Na - Bang Phli - Bang Pakong Expressway), officially Burapha Withi Expressway (Thai: ทางพิเศษบูรพาวิถี), is a 55 km[1] long 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 highway is elevated onto a viaduct that has an average span length of 42 meters. It is a 27-meter wide box girder bridge and was completed in January 2000. It took 1,800,000 cubic meters of concrete to build the bridge. 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).[2]

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).[3]

It is one of the longest bridges in the world (until 2010 it was the longest) but it is excluded from some lists since it does not cross a body of water for most of its length. The largest body of water that it crosses is the Bang Pakong River.
