4. Bang Na Expressway, Thailand

This overpass was completed in January 2000. It is 55km long, and 27metres wide. It was designed by Jean Muller (USA). It does not cross a big water mass in most of its length. It only crosses over the Bang Pakong River, and it is open for road traffic.

5. Beijing Grand Bridge, China

This bridge is 48.15km long, and it’s located in Beijing, connecting Beijing to Shanghai. It serves the High-speed railway transport. It was completed in 2010, and was opened officially in 2011.

6. Manchac Swamp Bridge

The Manchac Swamp Bridge is a twin concrete trestle bridge in the US state of Louisiana. It is located around Lake Pontchartrain, a lake well known for its incredibly long bridges, as you will see in a moment. Although the bridge is totally safe to drive on, Louisiana legend says that the bridge is haunted by a Cajun werewolf known as a “Rougarou” and a voodoo princess. However, despite these spooky tales, the only thing that drivers should be cautious of is not to get too close to the alligators that make a home on the waters under the bridge.

7. Lake Pontchartrain Causeway

The Lake Pontchartrain Causeway, or the Causeway, is considered to be the longest bridge in the United States and the longest bridge in the world over water (continuous). It consists of two parallel bridges crossing Lake Pontchartrain in southern Louisiana, United States. The longer of the two bridges is 23.83 miles (38.35 km) long. There was some controversy with Guinness over the title of the longest bridge over water. For over 10 years, Lake Pontchartrain Causeway was listed in the book for being the longest bridge over water.

However, in 2011, Jiaozhou Bay Bridge in China was given the title of the longest bridge over water. Many Lake Pontchartrain record holders in the U.S. disputed this with Guinness stating that the causeway ran for 23.79 miles over water; therefore, it was the longest. Guinness ended the controversy by creating two categories, one for the longest bridge (continuous), which was given to Lake Pontchartrain, and longest bridge (aggregate), which was given to Jiazhou.
