NEW YORK, NY June 30, 2008 —After months of excavation delays and fines, the Port Authority finally conceded that its property, the World Trade Center site, is seriously behind schedule. So much so, that the agency is throwing out a schedule it announced less than two years ago.

At that time, the Port Authority said the 9/11 memorial would be ready for its first visitors in 2011, the 10th anniversary of the terrorist attacks that brought the Twin Towers down. WNYC’s Matthew Schuerman tells Amy Eddings about the reasons behind the delays, and why the Port Authority isn’t ready to set a new timetable yet.
