The Bang Na Expressway (full name: Bang Na - Bang Pli - Bang Pakong Expressway), officially Burapha Withi Expressway (Thai: ทางพิเศษบูรพาวิถี), is a 54 km long six-lane elevated highway in Bangkok, Thailand. It is a toll road and runs above National Highway route 34,(Bang Na–Bang Pakong Road).

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 March 2000. It took 1,800,000 cubic meters of concrete to build the bridge. The structure was built using a design-build contracting method and was designed by Jean Muller International.

There are two toll plazas on the elevated structure where the structure must widen to accommodate twelve lanes.

It is sometimes considered to be the longest bridge in the world, but is excluded from some lists since it does not cross a body of water for most of its length.
