Chelsea, Manhattan in the context of "Hudson Yards (development)"

A neighbourhood (Commonwealth English) or neighborhood (American English) is a geographically localized community within a larger town, city, suburb or rural area, sometimes consisting of a single street and the buildings lining it. Neighbourhoods are often social communities with considerable face-to-face interaction among members. Researchers have not agreed on an exact definition, but the following may serve as a starting point: "Neighbourhood is generally defined spatially as a specific geographic area and functionally as a set of social networks. Neighbourhoods, then, are the spatial units in which face-to-face social interactions occur—the personal settings and situations where residents seek to realise common values, socialise youth, and maintain effective social control."

The West Side of Manhattan refers to the side of Manhattan Island that abuts the Hudson River and faces the U.S. state of New Jersey. The major neighborhoods on the West Side are (from north to south) Inwood, Hudson Heights, Washington Heights, West Harlem, Morningside Heights, Manhattan Valley, the Upper West Side, Hell's Kitchen, Chelsea, the West Village, SoHo, and Tribeca. The 8th Avenue and West Side subway lines connect all parts of the West Side.

The main north–south roads servicing the West Side are the Henry Hudson Parkway in the north and the West Side Highway in the south. The Hudson River Greenway separates these highways from the island's western shore.

Sixth Avenue, also known as Avenue of the Americas, is a major thoroughfare in the New York City borough of Manhattan. The avenue is commercial for much of its length, and traffic runs northbound, or uptown.

Sixth Avenue begins four blocks below Canal Street, at Franklin Street in Tribeca, where the northbound Church Street divides into Sixth Avenue to the left and the local continuation of Church Street to the right, which then ends at Canal Street. From this beginning, Sixth Avenue traverses SoHo and Greenwich Village, roughly divides Chelsea from the Flatiron District and NoMad, passes through the Garment District and skirts the edge of the Theater District while passing through Midtown Manhattan. Although it is officially named "Avenue of the Americas", this name is seldom used by New Yorkers.

The Flatiron District is a neighborhood in the borough of Manhattan of New York City, named after the Flatiron Building at 23rd Street, Broadway and Fifth Avenue. Generally, the Flatiron District is bounded by 14th Street, Union Square and Greenwich Village to the south; the Avenue of the Americas (Sixth Avenue) and Chelsea to the west; 23rd Street and Madison Square (or NoMad) to the north; and Park Avenue South and Gramercy Park to the east.

Broadway cuts through the middle of the district, and Madison Avenue begins at 23rd Street and runs north. At the north (uptown) end of the district is Madison Square Park, which was completely renovated in 2001. The Flatiron District encompasses within its boundaries the Ladies' Mile Historic District and the birthplace of Theodore Roosevelt, a National Historic Site. The Flatiron District was also the birthplace of Silicon Alley, a metonym for New York's high technology sector, which has since spread beyond the area.

The IRT Flushing Line is a rapid transit route of the New York City Subway system, named for its eastern terminal in Flushing, Queens. It is operated as part of the A Division. The Interborough Rapid Transit Company (IRT), a private operator, had constructed the section of the line from Flushing, Queens, to Times Square, Manhattan between 1915 and 1928. A western extension was opened to Hudson Yards in western Manhattan in 2015, and the line now stretches from Flushing to Chelsea, Manhattan. It carries trains of the 7 local service, as well as the express <7> during rush hours in the peak direction. It is the only currently operational IRT line to serve Queens.

It is shown in the color purple on station signs, the official subway map, and internal route maps in R188 cars. Before the line was opened all the way to Flushing in 1928, it was known as the Corona Line or Woodside and Corona Line. Prior to the discontinuation of BMT services in 1949, the portion of the IRT Flushing Line between Times Square and Queensboro Plaza was known as the Queensboro Line. Since the mid-2010s, the line's signal system has been converted to an automated system.

The 7 Flushing Local and <7> Flushing Express are two rapid transit services in the A Division of the New York City Subway, providing local and express services along the full length of the IRT Flushing Line. Their route emblems, or "bullets", are colored purple, since they serve the Flushing Line.

The 7 operates 24 hours daily between Main Street in Flushing, Queens and 34th Street–Hudson Yards in Chelsea, Manhattan, making all stops along the full route. Additional service operates along the full route and makes express stops in Queens between Mets–Willets Point and 74th Street–Broadway during rush hours in the peak direction instead of making all stops; these trains labeled as <7> Express trains. Super express service operates after special events at Citi Field or the USTA Billie Jean King National Tennis Center in the southbound direction only.
