The long-awaited and long-delayed World Trade Center transit hub is running behind schedule again. According to a Federal Transit Administration report, the $3.2 billion train station only has a 25 percent chance of being finished by its mid-2014 deadline—a date set when it became clear the project couldn't be finished by its intended 2011 deadline.

The Post reports that architect Santiago Calatrava's transit hub probably won't be completed in 2015 either. That's because two skyscrapers planned to flank the train station have also been delayed, potentially impeding construction on the hub. "Construction of Towers 2 and 3 could become the most significant source of risks associated with the [transit] project," the report noted. According to the tabloid, Port Authority engineers are now trying to figure out if they can build the transit hub before work begins on the towers, which are controlled by Ground Zero developer Larry Silverstein.

Since the 2005 groundbreaking, the World Trade Center transit hub has run into financial trouble. That has meant delays, and cost-cutting measures that have stripped Calatrava's winged creation of its planned column-less interior and retractable roof.
