Greenpoint Avenue station

New York City Subway station in Brooklyn
As part of the 2015–2019 Metropolitan Transportation Authority Capital Program, elevators were added to the platforms and street, which makes the station fully compliant with accessibility guidelines under the Americans with Disabilities Act of 1990. Construction started in September 2018 and was expected to be completed by December 2020, but opened a few days earlier in late November 2020. There are three elevators: one from the mezzanine to street level on the eastern side of Manhattan Avenue north of Greenpoint Avenue, and one to each platform. The project is expected to cost $23.4 million. The MTA announced in April 2024 that it would make esthetic improvements to the station during mid 2024 as part of its Re New Vation program, while the line was temporarily closed for construction.

This underground station has two tracks and two side platforms. The G stops at the station at all times. The station is between 21st Street to the north and Nassau Avenue to the south. Both platforms have a green trim line with a black border and mosaic name tablets reading "GREENPOINT AVE." in white sans serif font on a black background and green border. Directly below the trim line are tile name captions reading "GREENPT" in white lettering on a black background. Directional tile signs are below some of the name tablets. The tile colors were designed to facilitate navigation for travelers going away from Lower Manhattan. Because the Crosstown Line does not merge into a line that enters Manhattan at either end, all stations on the line had green tiles. Green I beam columns run along both platforms at regular intervals, alternating ones having the standard black name plate in white lettering. G trains, which are about half the length of the 600 feet (183 m) platform, stop near the south end of the station. Both platforms have an unstaffed, same level fare control area at their north ends. Each side has one exit only turnstile, two High Entry/Exit Turnstiles, and one staircase going up to the south side of India Street and Manhattan Avenue. The one on the Queens bound side goes up to the southeast corner while the one on the Church Avenue bound side goes up to the southwest corner.
