Fort Pike damaged after Issac set to reopen Fort Pike damaged after Issac set to reopen The Associated Press July 01, 2013 Comments NEW ORLEANS — Historic Fort Pike will reopen Tuesday after repairs in the wake of Hurricane Isaac. The fort, on the city’s eastern edge, was built after the War of 1812 to protect New Orleans from invasion. The state historic site will operate from 9 a.m. to 5 p.m. Tuesdays through Saturdays. The fort is off U.S. 90 at the Rigolets and had been closed due to damage from Isaac in August. The fort received an estimated $660,000 in damage, including an accumulation of 3 to 4 feet of marsh grass and mud deposited inside the fort. The manager’s residence was destroyed.
