Louisiana Coastal Protection and Restoration Authority (CPRA) is supporting the Hwy 1 Terracing Extension in Lafourche Parish through its 2025 Parish Matching Program, a targeted investment that expands ongoing coastal protection efforts and helps safeguard communities and essential transportation corridors.
According to CPRA, this extension will construct approximately 20,000 linear feet of earthen terraces to help reduce wave energy and provide added protection for LA Highway 1 and nearby levees, building on the larger Hwy 1 Terracing and Living Shoreline project currently under construction.
The broader project includes:
In March 2025, CPRA awarded Parish Matching Program funds through the Lafourche Parish Government to advance the Hwy 1 Extension.
Construction began in November 2025, marking another step forward in strengthening coastal infrastructure and reducing risk for coastal communities and critical transportation corridors, CPRA concluded.
