The Causeway is a symbol of human achievement, pushing the boundaries of engineering and design.

It’s constructed with precision and care to withstand the challenges posed by the vast lake and its ever-changing conditions.

Construction & Design

The construction of the Lake Pontchartrain Causeway began in the early 1950s.

It was completed in two phases:

  • Phase 1: The first span, the southbound bridge, opened to the public on August 30, 1956.
  • Phase 2: The second span, the northbound bridge, was added later and officially opened on May 10, 1969.

The Causeway boasts a unique design featuring more than 9,000 concrete pilings, creating a stable foundation for the bridge to rest upon.
