Lake Pontchartrain Causeway, United States
When it comes to long bridges over water, the U.S. excels. The Lake Pontchartrain Causeway is the longest bridge globally, totaling 23 miles. These bridges pose danger as they sit only 16 feet above water. Storms here are risky.
These bridges connect New Orleans to the North Shore, reducing residents’ lake-crossing travel time. Crossing takes merely 50 minutes one way.
