Sutter Avenue is a station on the BMT Canarsie Line of the New York City Subway. Located at the intersection of Van Sinderen and Sutter Avenues at the border of Brownsville and East New York, Brooklyn, it is served by the L train at all times.Station layoutThis elevated station, opened on December 28, 1906, has two tracks and two side platforms. The station is a microcosm of early-20th century BRT construction. Ornate period ironwork adorns the quaint wooden crosswalk beneath the south end of the station.This station was renovated in 2006, which included new windscreens (beige with green frames) and canopies (red with green frames) that run along the entire length of the platforms except for a small section at the north end and installation of yellow tactile warning strips on the edges. Artwork called The Habitat for the Yellow Bird by Takayo Noda was also installed and features stained glass windows of flowers on the windscreens.ExitThe only entrance is via a ground level station house underneath the tracks on the northwest corner of Sutter and Van Sinderen Avenues. Inside is a token booth, turnstile bank, and a single canopied staircase to each platform at their extreme south ends.Structure changes north of the stationNorth of this station, the Canarsie Line formerly split into two separate elevated structures, one above Van Sinderen Avenue and another a block east above Snediker Avenue via an "S" curve. This curve into was one of the sharpest in the subway at around 75 degrees. As the curve swung eastward, it passed under the last remnant of the Fulton Street Elevated. The tracks on this line curved east on their way to City Line, Brooklyn before ending at Pitkin Avenue. The two Canarsie elevated structures ran north into separate platforms at Atlantic Avenue.
