Louisiana's scour mitigation needs are among the most severe in the country, driven by hurricane storm surge and the Mississippi River's high flow energy, and DOTD bridges and levee-adjacent infrastructure face scour forces that far exceed the design assumptions built into much older Gulf Coast infrastructure.
It's a recurring example of the Washouts & Scour Damage conditions DOTD and local owners manage statewide.
Riprap and armor stone for Louisiana bridge crossings are sized for hurricane storm surge conditions, not just routine river flow, reflecting the state's exceptional storm exposure. This is one application of GSI's broader bridge solutions expertise.
Grout-filled mattress systems protect Louisiana's levee-adjacent infrastructure from the combined river current and storm surge scour the state's coastal parishes regularly experience. GSI's emergency bridge repair experience informs this approach.
Sheet pile and grouted rock protection at Louisiana bridge foundations addresses scour damage from both chronic Mississippi River flow and episodic hurricane storm surge. This draws directly on GSI's coastal and bluff stabilization work.
GSI's water infrastructure experience also informs how these Louisiana projects are scoped from the start.
Engineered for Louisiana's conditions. GSI's Louisiana scour mitigation is engineered for hurricane storm surge as the design condition — not an occasional exception layered onto standard river flow assumptions. Supported by transportation infrastructure and engineers.
Design/build delivery. One contract covers design and construction — avoiding the coordination failures that split design and build.
DOTD specification compliance. Design and construction records satisfy applicable DOT specifications starting with the first design package.
DOTD partners and Louisiana infrastructure owners describe GSI's scour mitigation results.
GSI's engineers are ready to assess scour mitigation conditions at your Louisiana site.
