Recent announcements by the Metropolitan Transportation Authority that construction of the Second Avenue subway is 80 percent complete is really modest progress.

Consider that it's 86 years since the project was announced in 1929, 65 years since full-financing bonds were issued for it in 1950, and 60 years since the Third Avenue elevated line was demolished with promises of a Second Avenue subway to replace it "soon" in 1955.

In that time, the proposed subway has been reduced from a six-track plan to two tracks, replacing six tracks worth of elevated lines on Second and Third avenues (both lines had center express tracks).

The good news is that the current portion of the work, based on the most recent project construction schedule, is proceeding on time and within budget. The current estimated use date is December 2016. Don't be surprised if this date slips to sometime in 2017.
