Until 1999, tolls were collected from traffic going in each direction. To alleviate congestion on the south shore, toll collections were eliminated on the northbound span. In May 1999, the standard tolls for cars changed from $ 1.50 in each direction to a $ 3 toll collected on

Supporters made this claim based on its own definition, i.e. the length of a bridge physically over water, and concluded that the Lake Pontchartrain Causeway spans 23.79 mi (38.28 km), and was therefore the longest. The Jiaozhou Bay Bridge spans water for only 16.1 mi (25.9 km). However, Guinness World Records , using the criteria of measurement that included aggregate structures, such as land bridges on

The idea of a bridge spanning Lake Pontchartrain dates back to the early 19th century and Bernard de Marigny ,
