Ground broken on World Trade transit hub

Ground was broken Tuesday at the new World Trade Center Transportation Hub. Designed by Santiago Calatrava, the $2.21 billion station will connect PATH trains with New York City subways and will also be equipped to one day receive Long Island Rail Road trains as well as a rail link from Kennedy Airport. The hub is expected to be operational in 2009, according to the Port Authority, and could serve as many as 80,000 commuters a day.
