Surcharge Testing

The Louisiana International Terminal is in the planning and design phase. Part of that process involves making sure we have a strong foundation on which to build. Our soil studies have given us valuable insight and a path forward. The next step in the development process is to validate those studies by performing different field tests. The first is a series of surcharge tests.

What is Surcharging?

Surcharging is a proven process that helps the ground settle faster. Here’s how the process works:

  1. The two test sites and access road are being cleared and prepped.
  2. A sand mound of approximately 20’ high will be constructed at each site.
  3. Then gravity will do the work! The weight of the sand will push down the soil underneath and consolidate the soil.

By surcharging, we can make the ground more compact and create a sturdier foundation for the terminal.

Why Do We Need to Surcharge? 

Before we construct the Louisiana International Terminal, we need to make sure we have a strong foundation on which to build.

When and Where?

Preparation of the two small test areas and driveway on the terminal site began in May 2024.

The U.S. Army Corps of Engineers has approved these tests, and the Port of New Orleans has mitigated for them. The Louisiana International Terminal is currently undergoing an environmental review process, as required under the National Environmental Policy Act (NEPA), before permits can be issued and construction can begin.

What Can You Expect?

While constructing the two test sites and access road, crews are onsite weekly, Monday through Friday, from 6:00 am - 5:00 pm. Saturdays will be weather-related makeup days.

Surcharge Testing Updates

To ensure safe and efficient operations while constructing the driveway and other areas for the surcharge test site, scheduled lane and shoulder closures will occur on westbound E. St. Bernard Highway at Springer Lane.

Shoulder Closure: Beginning the week of 6/17/2024 - Anticipated to last three weeks
The westbound E. St. Bernard Highway shoulder closure will occur between 8 a.m. and 3:30 p.m. Drivers can expect to see: 

  • "Road Work Ahead," "No Shoulder," and "End Road Work" signs along westbound East St. Bernard Highway
  • Traffic barrels and barriers along the shoulder
  • Local law enforcement can be expected and will be utilized as additional measures to help traffic when needed
  • Multiple construction vehicles positioned inside the shoulder closure performing work

Single Lane Closure: Beginning the week of 6/17/24 - Anticipated to last three weeks
The westbound E. St. Bernard Highway closure will occur between 8 a.m. and 3:30 p.m. on the scheduled dates. Drivers can expect to see: 

  • "Road Work Ahead," "One Lane Road Ahead," "Flagger" Symbols, and "Reduced Speed Limit" signs in each direction
  • Flagman/women at a flagging station to hold & direct traffic in each direction 
  • Traffic barrels and barriers taking the westbound travel lane
  • Local law enforcement can be expected and will be utilized as additional measures to help traffic when needed
  • Construction vehicles entering and exiting the lane closures (Dump trucks, tractor-trailers, equipment transports, and light-duty vehicles)

Port NOLA and team continue to monitor river levels and will send updates should schedule adjustments need to be made.
