Willets Point–Citi Field is an elevated subway station on the IRT Flushing Line of the New York City Subway. It is served by the train at all times, including express service running in the peak direction during rush hours and middays. Located in Flushing Meadows–Corona Park, Queens, on Roosevelt Avenue between 114th and 126th Streets, this station's peak use is during New York Mets baseball games at Shea Stadium and Citi Field, located on the north side of the station, and during events at the USTA National Tennis Center, on the south side.
This three-track express station has a layout unique in the system. From compass north to south, it is arranged: southbound side platform, southbound local track, bidirectional express track, island platform, northbound local track, northbound side platform. Trains running northbound (towards Main Street) open their doors on the island platform; the northbound side platform is used only during events at the National Tennis Center, such as the U.S. Open. On the south side of the station, a ramp connects the mezzanine and the northbound side platform to a footbridge, which passes over Corona Yard and the LIRR Port Washington Branch on its way to the National Tennis Center. A full-length wooden mezzanine is located underneath the tracks and platforms. The north side of the station used to feature a footbridge that extended over the street that would then bring people to a long, circular staircase that would bring people close to Shea Stadium. However, in 2008 the footbridge was removed and replaced with a stairway that is situated a little further from the construction of Citi Field. The stairway was most likely put in to ease foot traffic following Mets games.
Today, remnants of the original 1927 station can be seen just east of the current station. Ironwork indicates where the old side platforms had been, and parts of the former fare entry area remain. The southbound side platform is also noticeably longer than the 11-car IRT-length trains that serve it; a long segment east of the current passenger waiting area—part of the original southbound platform—has fallen into disrepair and has been gated off.
