[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.

[19] A request for proposals was put out on May 18, 2023 for the contract for a project bundle to make 13 stations accessible, including Broadway.

[24] As part of the MTA Arts & Design program, Diane Carr created an artwork for the station, titled Outlook, which was installed in 2018.

[28] According to Carr, the shapes in the artwork are inspired by the original landscape of the area, which once included swamps, ponds, woods, and meadows.

[29][30] An exit-only stair from the northbound platform descends to the east side of 31st Street between Broadway and 34th Avenue.
