The LPV-3.2 West Return Floodwall is a key piece of the U.S. Army Corps of Engineers' $14-billion mission to build the Greater New Orleans Hurricane and Storm Damage Risk Reduction System. The joint venture Odebrecht-Johnson Bros. led construction of the $94-million project.
Located on the east bank of the Mississippi River in Jefferson Parish, the West Return Floodwall runs along the St. Charles and Jefferson Parish line from Louis Armstrong New Orleans International Airport to Lake Pontchartrain. The project constructed a three-mile-long concrete T-wall on the Jefferson Parish lake front.
