The Port Authority Tuesday opened the first World Trade Center PATH station platform to riders.

"Platform A" is the first completed piece of the new WTC PATH Station, which will be the center of the nearly $4 billion WTC transportation and retail hub.

The PATH station will have five platforms, according to the Port Authority.

With the current PATH station handling more than 100,000 passengers a day, Steve Plate, director of WTC Construction, said the station will be capable of handling more than 160,000 riders.
