A major drainage upgrade is underway in Metairie, where crews are installing massive storm pipes beneath North Causeway Boulevard. The project is part of a broader effort to reduce frequent street flooding that has long affected the busy corridor.
Major Pipe Installation Underway
Workers have been lowering 72-inch reinforced concrete pipes beneath North Causeway Boulevard, marking a key phase of the nearly $10 million project.
The large-scale operation involves heavy machinery, deep trenching, and backfilling as crews work to improve how stormwater is managed in the area.
Why the Upgrade Matters
The new pipes are designed to significantly increase the system’s capacity to carry water during heavy rainfall.
According to the Louisiana Department of Transportation and Development, larger pipes and deeper installation levels help move water away faster, reducing the risk of street flooding.
Part of a Bigger Project
This drainage work is just one piece of a larger upgrade along North Causeway Boulevard.
Plans include widening the roadway, improving curbs and gutters, and enhancing overall infrastructure between key intersections. The broader project is estimated to cost around $25 million and began construction activity in late 2025.
What Drivers Should Expect
With construction in full swing, drivers can expect lane closures, delays, and possible detours in the area.
Officials recommend planning ahead when traveling through the corridor, as work will continue in phases and may impact traffic patterns.
Regional Flood Prevention Efforts
The project reflects a wider push across the New Orleans metro area to address flooding.
Nearby parishes are also investing in drainage improvements, including new pump stations and stormwater systems, as communities work to better handle heavy rain events.
Looking Ahead
While a firm completion date for this phase has not been announced, the work represents a significant step toward improving drainage in Metairie.
Residents are encouraged to follow updates from local officials for the latest information on progress and traffic impacts as the project continues.
