On Friday, crews in Metairie were busy lowering 72-inch storm pipes beneath North Causeway Boulevard, part of a nearly $10 million drainage upgrade aimed at cutting down the corridor’s all-too-familiar street flooding. Heavy machinery and massive concrete segments crowded the roadway, marking a highly visible phase of what officials describe as a multi-phase effort to boost stormwater capacity along the busy Causeway corridor.
As reported by NOLA.com, photographers captured crews setting the 72-inch reinforced concrete pipe and backfilling trenches along North Causeway Boulevard, with Kim Chatelain credited for the images. NOLA.com’s coverage lists the local drainage contract at $9.85 million and describes the project as focused on easing recurring street flooding in the area.
What Crews Are Installing And Why
Engineers selected 72-inch reinforced concrete pipe to increase how much stormwater the system can carry and to move water off the roadway faster. Design materials from the Louisiana Department of Transportation and Development for Causeway Boulevard show pipe sizes ranging from 15 inches up to 72 inches, with invert depths of roughly 11 feet below grade. According to the Louisiana DOTD, upsized conduits and deeper inverts are standard tools for cutting down on surface inundation during heavy rain.
How This Fits Into A Broader Corridor Upgrade
The pipe work appears to be one piece of a larger North Causeway Boulevard widening and drainage upgrade that would add lanes and improve curbs and gutters between West Napoleon Avenue and Airline Drive. A planning listing on ConstructConnect shows a related Metairie project valued at roughly $25 million, with construction activity flagged to begin in late 2025.
What Drivers And Neighbors Can Expect
Work of this scale typically means lane closures and temporary traffic control, so commuters should be ready for intermittent delays near the construction zone while crews set pipe and rebuild pavement. Jefferson Parish has carried out similar drainage repairs around North Causeway in past years, as earlier coverage of lane closures shows, and drivers using the corridor should plan for occasional detours as the project moves along.
Part Of A Regional Push On Flooding
The Causeway work is just one front in a broader regional push to shore up stormwater infrastructure. Neighboring parishes have been moving ahead with pump station projects and other upgrades aimed at protecting neighborhoods from frequent inundation. St. Charles Parish recently broke ground on permanent pump stations for Montz in a multiyear, multimillion-dollar effort, highlighting a metro-wide push to reduce street and yard flooding across the New Orleans area…
