Small section of Hwy. 3235 and Hwy. 1 expected to be modified in near future
Work is expected to begin soon on levee improvements in the vicinity of the Ted Gisclair floodgate in Larose.
In the coming months, an “I wall” will be placed in front of Holy Rosary Catholic Church in Larose to meet with the levee near the floodgate in Larose.
This improvement work will raise the levee from a height of eight feet to approximately 13 feet. The work is expected to take eight to 10 months to complete. Sheet piles with an “A frame” will also be placed near the floodgates to provide additional strengthening and protection.
Improvement work is also ongoing on the east side of the Intracoastal Canal where sheet piles are being placed to increase the levee heights in this area, also from eight feet to approximately 13 feet.
This $6 million project should be completed in the next few months.
The funding for these projects comes from a variety of sources, including tax revenue, state capital outlay and excess funds from prior projects.
Work is also expected to begin soon on raising the small portion of LA Hwy. 3235 where the four-lane highway crosses over the ring levee in Larose.
“The levee currently sits at 13 feet while the roadway is a height of nine feet,” said Windell Curole, general manager of the South Lafourche Levee District.
The approximately $600,000 project to raise the road to a height comparable with the levee is expected to begin in December and be completed by early summer of next year. While the work to raise the height of Highway 3235 is fairly straightforward, the work to raise Highway 1 where it intersects with the levee near the Leon
Theriot floodgate south of Golden Meadow is a bit more complicated.
With a new elevated highway expected to be completed in the area in the next decade, thus rendering the current LA 1 to a diminished capacity, engineers are considering a less costly version than raising the road, for this section of highway.
“Instead of raising LA 1 near the floodgate, a more cost effective method, with a new road coming, could be to place a steel barricade that would lift up from the roadway when needed, much like the barricades seen protecting the White House and U.S. Capitol,” said Curole.
In this area, the highway sits at a height of 13 feet while the levee is now at 18 feet.
“We’re trying to find the most cost effective way to close that gap in the system while making sure what we choose is an adequate form of protection,” he said.
