Hurricane Katrina damage to the Interstate 10 Twin Spans

The I-10 Twin Spans bridges were destroyed by Hurricane Katrina, but the concrete rubble from the structures will be used inside gabion mattresses to line a 7.8-mile stretch of the Lake Borgne shoreline to reduce erosion of the eastern New Orleans landbridge.

(Louisiana Governor Bobby) Jindal said recycling concrete from the I-10 bridge, instead of buying concrete for the project, resulted in a $11.55 million savings for the project. Concrete from the bridge also is being used to build fishery reefs in Lake Pontchartrain, and a fishing pier in Slidell.
