6 of 20 Lake Pontchartrain Causeway (Louisiana, USA)
This bridge is the longest and among the world’s scariest as it stretches 23.83 miles and sits just 16 feet above Lake Pontchartrain’s choppy waters. Since 1969, the Pontchartrain Causeway has held the record for being the world’s longest bridge that is over water. Its construction greatly helped the economy of the surrounding small communities in North Shore by reducing the time it takes to drive into New Orleans by as much as 50 minutes. Now, the communities can access the Metropolitan city more conveniently.
