The Smith-9th Sreet station, considered to be the world's highest subway station, has been closed since June of 2011 for reconstruction.
Repairs to the Gowanus station took much longer than anticipated, with complications arising from the replacement of a viaduct originally built in 1933.
The stairs have been rehabilitated, along with the platform, and a new metal escalator enclosure installed.
F and G trains will once again be stopping at the station, which used to see more than 4,000 riders a day before it was closed.
The MTA says some work will continue after the station reopens but it will not affect service.
