The tunnel-boring machine that carved out the massive cavern for the new 34th Street Station that will be part of the Number 7 subway extension at the Hudson Yards in Manhattan is photographed, Wednesday, Feb. 3, 2010 in New York. The $2.1 billion project, funded by the city and managed by the MTA, is the first subway expansion in decades. In December, the second of two tunnel-boring machines reached the southern wall of the 34th Street Station cavern after mining a combined 2,900 feet from their starting point at 26th Street under 11th Avenue. The machines are now drilling tunnels north of 34th Street towards 42nd Street. (AP Photo/Mary Altaffer)
