The parish is preparing to replace an existing 60-inch corrugated metal culvert under Ormond Boulevard in Destrehan, a project that will force traffic detours on the major thoroughfare.
The new structure will consist of a wider concrete arch culvert supported by pilings, according to Volkert and Associates, the engineer on the project. Water flow under the boulevard would be increased from 350 cubic feet per second to 1,413 cubic feet per second. The pathway drains subdivisions west of Ormond Boulevard to the Destrehan I pumping station.
The parish is spending additional design time on this particular project due to its location near major utilities, including water, sewer, phone, cable, gas and electrical infrastructure. This will insure residents are provided with a safe alternative traffic route and cost-effective management of utility lines that would be affected.
Once the project is started, construction is expected to last 120 days in two phases. Pedestrian and bike traffic will not be allowed in the area for the duration of the project. Lane detours will affect traffic in both directions, with one lane being open to traffic north and south.
The mission of St. Charles Parish government is to provide high quality, efficient services to sustain and enhance the quality of life for all residents of St. Charles Parish.
