[16] The Broadway and 39th Avenue stations were closed entirely on July 2, 2018, and reopened on January 24, 2019, slightly earlier than expected.

[17] A previously demolished entrance to the northeast corner of Broadway and 31st Street was added once again to improve access.

As part of the MTA Arts & Design program, the British-American painter Sarah Morris created an artwork for the station, titled Hellion Equilibrium, which was installed in 2019.

[22] The artwork, installed on the walls of each platform, consists of multicolored shapes that allude to the station's GPS location.

Outside fare control, there is a token booth and two staircases going down to the northwest and southeast corners of 39th Avenue and 31st Street.

The lower base of the platform staircases have emergency gates leading directly to the top of the street stairs.
