Livonia Avenue has two side platforms on the Canarsie Line's embankment. The 3 train's elevated over Livonia Avenue passes straight through and above the station's platform. There is a walkway and bridge over some non-revenue tracks that are parallel to the station that leads directly to an entrance to the Junius Street Station. Residents have been asking for a free transfer for many years, a free MetroCard Transfer was finally added temporarily for the reconstruction of the Canarsie Tubes in 2019 and made permanent during tin 2020 with the building of an in system, fully ADA Accessible transfer (and exits from the station) between the two stations is scheduled to be built by 2024. If the Interborough Express is every built on these former Bay Ridge Branch Freight tracks, it should have a station at this location with easy transfers to the L and 3 trains.
The station has one main exit located beneath the platforms towards the middle of the two side platforms for the two track L train line. Staircases lead down from each platform to an intermediate level before becoming one staircase that goes down into the station's tiny station house that is located at street level, across from a T-intersection where Livonia is interrupted (the line continues on the opposite side of the subway and freight tracks) at Van Sinderen Av, the 3 train which is an elevated above Livonia Avenue, crosses directly over the station house and station above.
In the small plaza across from the entrance house at street level there is also a staircase with a sign saying Overpass to Livonia Avenue & Junis Street (3) Station with another sign pointing towards the L train station house. This staircase leads up to an intermediate landing where a very short staircase continues up to a set of two High Entrance/Exit turnstiles directly on the Canarsie-bound platform before continuing onto the bridge over the freight tracks and the Junius Street Station on the 3.
The two side platforms were renovated in 2005-2006 and are wind-screened in their middles and exposed towards their ends. An Art's For Transit Installation was installed in 2007 but by 2009 was removed before returning by 2012. The MTA's website has a page for it with pictures, and NYCSubway.org has pictures taken in September, 2007. I've been trying to figure out why the artwork was briefly removed and can't find an answer.
The station was renovated again to become fully ADA accessible. This required the Canarsie-bound platform closed from November 15, 2020 to March 9, 2021, and the Manhattan-bound platform from March 29, 2021 to June 14, 2021. These renovations primarily built a small bridge above the platforms.
This new mezzanine is at the same level and just north of the 3 train's crossing above the L train and is part of phase 1 of building a new in subway-system transfer at this location. The mezzanine is accessed via a staircase and elevator up from each L train platform. The elevator to the Rockaway Parkway-bound platform stops at this platform at an intermediate mezzanine before continuing down to the station house at street-level under the tracks. The Manhattan-bound platform only has two landings with the bridge required to be used for step-free access entering and exiting the station. The mezzanine is completely canopied but not enclosed with a mixture of full height mesh on the sides. Tall panes of glass form a 'barrier' along the sides of the mezzanine allowing nice views down to the L train tracks below, and 3 trains just a short distance at the same level as the mezzanine.
