Someday, it's going to happen. A clean, modern subway train is going to pull up, right on time, at a station below Second Avenue on the Upper East Side. And when that day comes, Upper East Siders of all stripes are going to be happy. Upper East Side green condos will be that much greener, given their newfound proximity to mass transit; Upper East Side residents will see their commutes made simpler, quicker and less excruciatingly packed; Upper East Side condominiums will appreciate in value. The sun will shine every day and every man, woman and child will get a pony. The first three outcomes of the long-awaited, currently in-progress Second Avenue Subway are actually pretty reasonable -- more mass transit access will mean a better Upper East Side, and more valuable Upper East Side apartments. But, in news that's both saddening and sadly unsurprising, it looks like UES residents are going to have to wait a little bit longer for the Second Avenue Subway. And by "little bit" we mean "two years."
