If constructed with one platform, the 72 St station should favor one side of Second Avenue, much the way the 4th Ave line in Brooklyn was built on one side of the street so it could be expanded to four tracks later. At least leave some provision for adding the second platform, even if it goes the way of the Utica Avenue subway.Not a bad sentiment, but: Keep in mind, though, that this is mostly TBM construction. If MTA decides to narrow the tunnel diameter, even if the tunnel is itself left-justified or right justified, with respect to the 2nd Av median, it could still be prohibitively costly to work the unworked side. |
