The Lake Pontchartrain Causeway holds the title for the longest bridge over water at 23 miles long. It officially opened in 1956, and cut travel time from North Shore communities to the city of New Orleans by 50 minutes. The Causeway operates as a toll road, and offers a majestic view of the lake as you lose sight of land in all directions along the 23 mile drive.
The causeway is a true engineering marvel, and carries travelers across the Lake Pontchartrain, the largest inland body of water in Louisiana. A manufacturing plant was designed specifically for the construction of the bridge, and took a total of 14 months and 30 million dollars to complete.
As you cruise down the 23 mile stretch you get a view of three distinct bodies of water, the Gulf of Mexico the Mississippi Delta and Lake Pontchartrain. Prefabricated concrete sections were pieced together over the lake by large barges.
The bridge took 14 months to complete opened Aug 30th 1956. On May 10th 1969 the second bridge opened in response to high traffic volumes, and the threat of head on collisions that were occurring on the first bridge. There are already talks of constructing a third bridge in the near future.
