The World Trade Center Transportation Hub is set to be one of the City's most massive changes to New York's subway system. The building will have access to PATH trains, 13 subway lines and even the proposed JFK rail link. Sounds awesome, but how much will it cost taxpayers? The New York Post is reporting that the proposed cost will increase "by a staggering $180 million." (That's 40 million round-trip subway rides to work!) This brings the total cost to $3.44 billion.
