In August 2005, Hurricane Katrina sent surges of water into the New Orleans Inner Harbor Navigation Canal. The water overflowed canal walls and levees, causing major destruction. To protect the city and her people from hurricane damage in the future, the U.S. Army Corps of Engineers initiated construction of the Seabrook Gates Complex across the canal.
At the center of the structure is a sector gate consisting of two steel leaves that swing horizontally and close the 95-foot-wide navigational canal. Each steel gate leaf weighs 220 tons. On either side of the sector gates there is a 138-ton vertical lift gate. Hillsdale fabricated the gates in St. Louis and shipped them to New Orleans on barges from our port on the Mississippi River.
