Elmhurst Avenue station

New York City Subway station in Queens
The first section of the line opened on August 19, 1933 from the connection to the Eighth Avenue Line at 50th Street to Roosevelt Avenue in Jackson Heights. Later that year, a $23 million loan was approved to finance the remainder of the line, along with other IND lines. The remainder of the line was built by the Public Works Administration. In 1934 and 1935, construction of the extension to Jamaica was suspended for 15 months and was halted by strikes. Construction was further delayed due to a strike in 1935, instigated by electricians opposing wages paid by the General Railway Signal Company. The chief engineer of the Elmhurst Avenue station was Robert Ridgway and the design engineer was Aaron I. Raisman. In August 1936, tracks were installed all the way to 178th Street, and the stations to Union Turnpike were completed. The E train, which initially served all stops on the new extension, began making express stops in April 1937, and local GG trains began serving the extension at the time.

The opening of the Elmhurst Avenue station resulted in the development of Elmhurst as a commercial and residential neighborhood.

There are four tracks and two side platforms; the two center express tracks are used by the E and F trains at all times except late nights. The E and F trains serve the station at night, the M train serves the station on weekdays during the day, and the R train serves the station at all times except late nights. The station is between Jackson Heights–Roosevelt Avenue to the west and Grand Avenue–Newtown to the east. Both platform walls have a blue tile band on a black border with small "ELMHURST" tile captions in white lettering on a black background beneath them. They also have mosaic name tablets reading "ELMHURST AVE." in white sans serif lettering on a black background and Cerulean blue border. The tile colors were designed to facilitate navigation for travelers going away from Lower Manhattan. As such, the blue tiles used at the Elmhurst Avenue station are also used at , the next express station to the west, while a different tile color is used at , the next express station to the east. Blue tiles are similarly used at the other local stations between Roosevelt Avenue and 71st Avenue. There are also advertising recesses between the tablets, as well as grates at the top of the platform wall. On the southeast (railroad north) side of the mezzanine, there are two staircases going up to either southern corner of 45th Avenue and Broadway. Another goes up to the northwest corner of Elmhurst Avenue and Broadway, which is built within a store front and goes through a small underground shopping arcade. On this side, there are two exit only turnstiles and one High Entry Exit Turnstile from the Forest Hills bound side and two High Entry Exit Turnstiles from the Manhattan bound side. Between this station and Jackson Heights–Roosevelt Avenue, there are holes on the tunnel's ceiling, which accommodate the never used tunnels coming from the Roosevelt Avenue station's unused upper level terminal.
