[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.

[21] Both platforms have windscreens that run along their lengths and red canopies with green support columns in the center.

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.

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