In case you were thinking of getting off campus, MTA service this weekend is a bit weird, according to the MTA website. Both downtown and uptown 1 service is interrupted---especially frustrating is that downtown trains will skip stops around us.
South Ferry-bound trains skip 137, 125, 116, 110 and 103 Sts
This means that downtown trains will only be running from 96th Street. MTA recommends you take the 1 train uptown to 145th and then transfer for the downtown. I would take the B or C from 116th Street and then transfer to the 1 at 59th.
Van Cortlandt Park-bound trains skip Franklin, Canal, Houston and Christopher Sts
Once again, the C train can probably help you here. The 1 is running express from Chambers to 14th Street, but the C will be making local stops at Fourth Street, Spring Street, and Canal Street.
