If you have a fear of heights, please hold on tight. We’re introducing the 20 most dangerous bridge tops in the world that will make your hands and feet tremble.

Lake Pontchartrain Causeway (USA)

The Lake Pontchartrain Causeway in Louisiana, USA, is a toll road spanning Lake Pontchartrain for a total of 38.42 km (about 24 miles). To put that into perspective, the length of this bridge is roughly equivalent to a full marathon! The toll is $3, collected only when traveling southbound from Mandeville. It used to be $1.50 each way, but the change was made to ease congestion.

As for the scenery, many find it less than inspiring during the drive, with some even describing it as “boring.” It was once recognized by Guinness World Records as the longest continuous bridge in the world. However, bridges of greater length have since opened, and the record has been surpassed.
