In February, the city created the Hudson Yards Infrastructure Corp., a not-for-profit designed to help with the financing of the massive project. City estimates peg the total costs of the infrastructure to be financed through 2012 to be $2.8 billion and a continued buildout is expected to follow through 2040. Key elements of the plan call for the expansion of the #7 subway line with major stops at 34th Street and 11th Avenue and 41st Street and 10th Avenue as well as the creation of a platform over the Eastern Rail Yards, from 30th & 33rd streets between 10th & 11th avenues, to create a six-acre park and to allow for development by private developers and cultural institutions. Other infrastructure improvements will include a new street system and parks.

The not-for-profit RPA, which has been in existence for more than 80 years, notes that transportation improvements will be vital to the entire project. "The need to modernize and expand transit capacity is a basic requirement for supporting new commercial and residential development throughout New York City and the metropolitan region," it said in a report.

The Hudson Yards planning area extends from West 28th Street on the south, Eighth Avenue on the east, West 42nd Street on the north, and the Hudson River on the west. It is predicted to bring as much as 28 million sf of commercial office space, 12.6 million sf of residential space, 960,000 sf of hotel space and 680,000 sf of retail space to the area over the next 30 or so years. RPA calls for there to be coordinated efforts with the revitalization of Lower Manhattan, and even expanded office and residential development in the other boroughs and Northern New Jersey.
