MSNBC's Maddow takes us into the Second Avenue subway construction

Ah, the Second Avenue Subway, the line that has taken a lifetime to be built. There had been two elevated lines in the vicinity, at the start of the twentieth century, the Third Avenue Elevated and the First Avenue Elevated.
As Rachel Maddow reminds us, in the MSNBC clip at the right, the Metropolitan Transit Authority (MTA) and its predecessor authorities have had fitful starts at constructing it, in the 1920s, the 1950s, the 1970s.
Finally, the MTA has started constructing the Second Avenue, beginning in 2007.

Alas, it is projected that New Yorkers must wait until 2016 for the first leg of the subway, between 96th Street and 63rd Street. The subway will be an IND line, a northward continuation of the Q Line, that presently terminates at 57th Street.
