[5] It was built as an elevated line because the ground in this area is right above the water table, and as a result the construction of a subway would have been prohibitively expensive.

The out-of-system transfer is made via an overpass running parallel to the New Lots Line, which allows pedestrians on Livonia Avenue to cross over the Long Island Rail Road's open-cut Bay Ridge Branch.

[14][15] In 2015, there were proposals to convert the overpass into a free-transfer passage between the two stations, due to increasing ridership and plans for additional housing in the area.

[18] A free MetroCard-only transfer between the two stations was also provided during weekends and late nights as part of the reconstruction of the 14th Street Tunnel starting in April 2019[19][20] and introduced permanently in February 2020.

[21] The 2020–2024 Capital Program added back funding for the project, with an allocation of $38.4 million;[22] by January 2020, only $400,000 of that amount had been spent on "pre-design" activities.

[28] At Junius Street, a block from the station entrance, an overpass running parallel to the New Lots Line allows pedestrians on Livonia Avenue to cross over the Long Island Rail Road's open-cut Bay Ridge Branch.

The small, elevated mezzanine/station house beneath the tracks has a token booth, turnstile bank, and two staircases to the center of each of the two side platforms.
