Shaw’s Haser says that remaining work on the IHNC surge barrier includes, but is not limited to: placement of scour protection at various locations; installation of mechanical, and electrical controls for the sector gates and barge gate; construction of approach walls; tower and bridge fabrication and erection at the Bayou Bienvenue gate; and mechanical, electrical and control systems at Bayou Bienvenue.

All three gates in the barrier are expected to be operational by this hurricane season, but will not be complete until 2012.
