BATON ROUGE, La. – Today, the Louisiana Department of Transportation and Development (DOTD) announced plans to improve I-10 to address flooding due to storm surge at I-10 near LaPlace and I-55 near Ponchatoula.
A project to raise the elevation on I-10 near LaPlace is scheduled to begin this summer, with a September completion date. The work will eliminate a low point in the roadway and add approximately 15 inches of asphalt to the existing roadway. Additionally, a project to raise the grade of the I-10 ramps at the LA 3188 (Belle Terre) Interchange to prevent flooding is scheduled to be let to construction in 2015.
DOTD is conducting a hydrologic and hydraulic study of water flow and movement for the I-10 corridor between the Reserve Relief Canal Bridge and U.S. 51 that will include the interchange at U.S. 51 and the connection to the I-55 ramps. The study will identify options for current storm conditions as well as potential elevating alternatives and an elevated bridge section alternative for a 50-year and 100-year storm event.
Design is also underway for a project to eliminate a low spot just north of the elevated section of I-55 near Ponchatoula, with work scheduled to be let to construction in spring 2014.
DOTD has contracted the services of barrier dam companies, to be activated if necessary, for both locations.
