Barriere demolished each cross street, dug out the canal and installed 55’ wide and 11’ tall double barrel concrete box culvert, and then rebuilt the six cross streets over the recently re-engineered canal running on Gen. DeGaulle. Crews primarily worked in a large drainage ditch located between a set of sand dams that kept water out of the work area and routinely fought New Orleans’ weather to keep the work site dry. Barriere completed the difficult project with less than .001% of rework.
