Located at the intersection of Morgan Avenue and Harrison Place in East Williamsburg, Brooklyn, it is served by the L train at all times.

[10] In September 1924, the BOT approved the remaining section of the route between Eldert Street and Broadway Junction in East New York.

East of Eldert Street, the route would turn south to a ground-level alignment parallel to the LIRR's Bay Ridge Branch, then run southeast in a tunnel underneath private property to the intersection of Eastern Parkway and Bushwick Avenue, where it would emerge onto a ramp leading to the existing Canarsie elevated.

[11] An ornamental viaduct over Bushwick Avenue and Eastern Parkway was removed from the original plans due to opposition from property owners.

[14][15][16] In 2024, the MTA installed low platform-edge fences at the Morgan Avenue station and several others on the Canarsie Line to reduce the likelihood of passengers falling onto the tracks.

Both platforms have their original BMT style mosaic trim line and name tablets that are predominantly earth tones of brown, tan, and orange with white accents.

[20] All of them have name plates reading "MORGAN AVE" in black sans serif lettering on a white mosaic background.

A turnstile bank leads to a mezzanine with a token booth and three street stairs going up to all corners of Morgan Avenue and Harrison Place except the northwestern one.

[21][25] There are two exit-only and one High Entry/Exit turnstiles inside and one staircase to each platform at their west (railroad north) ends.
