Driving across most bridges is a quick journey over water, but the Lake Pontchartrain Causeway in southeastern Louisiana is a unique exception. This structure, consisting of two parallel bridges, spans Lake Pontchartrain, with the longer bridge measuring 23.83 miles, earning it the Guinness World Records title for the longest continuous bridge over water.
Constructed in 1956 at a cost of $46 million (equivalent to about $410 million today), the Lake Pontchartrain Causeway project involved the installation of 9,500 concrete pilings to support the massive structure. Approximately eight miles from the northern end, there is a large twin drawbridge that opens to accommodate marine traffic, requiring boats to give at least a three-hour notice for the bridge to be raised.
The causeway has significantly benefited the connectivity of small communities on the North Shore to New Orleans, reducing commute times to less than an hour for many residents who now have a more direct route. The toll for drivers to cross each way is $6.00, approximately £4.50, with discounted rates available for commuters.
Although the causeway enhances transportation, crossing it can be daunting. Many first-time drivers have reported experiencing panic attacks while crossing the bridge, which takes about 25 to 30 minutes to traverse. An eight-mile stretch without any visible land can be anxiety-inducing for motorists, leading some to share their apprehensions on platforms like Reddit.
Visitors crossing the causeway may also be wary of the presence of alligators in Lake Pontchartrain, although sightings near the causeway are rare. The bridge is equipped with designated bays where distressed drivers can pull over, and a dedicated police force patrols the area, assisting motorists in times of distress.
On the northern end of the bridge lies Mandeville, a vibrant city renowned for its jazz heritage, exemplified by establishments like Ruby’s Roadhouse and Dew Drop Jazz & Social Hall. Travelers can explore the Tammany Trace, a former railway converted into a walking and cycling trail, offering access to Louisiana’s lush wetlands. Fontainebleau State Park nearby provides opportunities for kayaking, hiking, and wildlife observation, adding to the diverse experiences in the region.
