AVONDALE, La. — The amphibious transport dock New York, built with 7.5 tons of steel from the World Trade Center site, is heading to its namesake city.

The warship built in south Louisiana, is to leave Tuesday. The Navy will officially commissioned it in New York in early November.

Organizers of a “line the levees” event in the New Orleans area hope several thousand people turn out Tuesday morning for the send-off.

One organizer, Lola Lass, says she expects a festive, patriotic scene. Flags were to be handed out to people gathering at a riverfront park.

Thousands of workers helped build the ship at Northrop Grumman Shipbuilding’s yard in Avondale.

A company spokesman says two ships under construction — Arlington and Somerset — will join the New York as 9-11 “tribute” ships.
