Plus, neither side can agree on who will pay the $300 million security costs the site will incur. Bloomberg's spokesperson indicated that the mayor's office is "confident" that the disputes will be ironed out, but monetary disputes have plagued the project since its inception.The Port Authority has dragged its feet at every opportunity on the rebuilding project, all while the one part of the project that is wholly within Port Authority aims, the PATH terminal/track rebuilding, is so far over budget as to be laughable.
