The main transit hall is 365 feet long (which is longer than the main concourse of the Grand Central Terminal). Over 12,500 tons of specially designed structural steel was used to construct its centerpiece, the Oculus, with rib-like structures extending toward the sky. The Oculus contains multi-level art, retail and dining amenities. The concourses which spring from the Oculus link the entire center above and below grade.

The new transit center will serve an estimated 250,000 daily commuters and visitors.  It connects eleven subway lines and provides commuter access to the Port Authority Trans-Hudson (PATH) system, the Battery Park City Ferry Terminal, the World Trade Center Towers and Memorial, the World Financial Center and the Winter Garden.
