Station renovations

The platforms at this station, along with six others on the Astoria Line, were lengthened to 610 feet (190 m) to accommodate ten-car trains in 1950.^[12]: 23 The project cost $863,000. Signals on the line had to be modified to take the platform extensions into account.^{[13]: 633, 729}

Under the 2015–2019 MTA Capital Plan, the station underwent a complete overhaul as part of the Enhanced Station Initiative and was entirely closed for several months. Updates included cellular service, Wi-Fi, USB charging stations, interactive service advisories and maps.^[14][15] The award for Package 2 of the renovations, which covered renovations at the 30th Avenue, Broadway, 36th Avenue, and 39th Avenue stations, was awarded on April 14, 2017, to Skanska USA.^[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.^[18]

In 2018 the MTA installed hand-painted laminated glass murals in the elevated walkway. The artwork, Outlook, was created by Diane Carr and fabricated by Peters Studios / Glasmalerei Peters.^[19][20][21]

In 2019, the MTA announced that this station would become ADA-accessible as part of the agency's 2020–2024 Capital Program.^[22] A contract for two elevators at the station was awarded in December 2023.^[23]
