Lake Pontchartrain Louisiana ☎ +1 800-634-9443 Last Updated: 07/11/2025 |
| Lake Pontchartrain is an estuary located in southeastern Louisiana. The first thing visitors notice about Lake Pontchartrain is how big it is. That observation often is made as they cross the Lake Pontchartrain Causeway Bridge, a 24-mile-long parallel pair of spans known as the longest bridge (continuous) over water in the world. | |
| Lake Pontchartrain covers an area of 630 square miles (1,600 km2) with an average depth of 12 to 14 feet (3.7 to 4.3 m). Some shipping channels are kept deeper through dredging. It is roughly oval in shape, about 40 miles (64 km) from west to east and 24 miles (39 km) from south to north. Some folks -- known as fraidy cats -- panic as land disappears behind them in the rear view mirror and the bridge seems to go on and on. Others enjoy the ride, and the view of pelicans, cormorants and occasional sailboats gliding by. Sunsets are gorgeous from the bridge. | |
