4. Lake Pontchartrain Causeway

3. Bang Na Expressway

The Bang Na Expressway is a 55 km long six-lane elevated highway in Thailand. It is often considered to be one of the longest bridges in the world (until 2010 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.
