Park Avenue is a boulevard in New York City that carries north and southbound traffic in the boroughs of Manhattan and the Bronx. For most of the road's length in Manhattan, it runs parallel to Madison Avenue to the west and Lexington Avenue to the east. Park Avenue's entire length was formerly called Fourth Avenue; the title still applies to the section between Cooper Square and 14th Street. The avenue is called Union Square East between 14th and 17th Streets, and Park Avenue South between 17th and 32nd Streets.
The Second Avenue Subway is a New York City Subway line that runs under Second Avenue on the East Side of Manhattan. The first phase of this new line, with three new stations on Manhattan's Upper East Side, opened on January 1, 2017. The full Second Avenue Line, if it will be funded, will be built in three more phases to eventually connect Harlem–125th Street in Harlem to Hanover Square in Lower Manhattan. The proposed full line would be 8.5 miles (13.7 km) and 16 stations long, serve a projected 560,000 daily riders, and cost more than $17 billion.
Second Avenue is located on the East Side of the New York City borough of Manhattan extending from Houston Street at its south end to the Harlem River Drive at 128th Street at its north end. A one-way street, vehicular traffic on Second Avenue runs southbound (downtown) only, except for a one-block segment of the avenue in Harlem. South of Houston Street, the roadway continues as Chrystie Street south to Canal Street.
Sixth Avenue – also known as Avenue of the Americas, although this name is seldom used by New Yorkers – is a major thoroughfare in New York City's borough of Manhattan, on which traffic runs northbound, or "uptown". It is commercial for much of its length.
The New York and Harlem Railroad was one of the first railroads in the United States, and was the world's first street railway. Designed by John Stephenson, it was opened in stages between 1832 and 1852 between Lower Manhattan Island to and beyond Harlem. Horses initially pulled railway carriages, followed by a conversion to steam engines, then on to battery-powered Julien electric traction cars. In 1907, the then leaseholders of the line, New York City Railway, a streetcar operator, went into receivership. Following a further receivership in 1932, the New York Railways Corporation converted the line to bus operation. The Murray Hill Tunnel now carries a lane of road traffic, but not the buses.
Lexington Avenue, often colloquially abbreviated as "Lex", is an avenue on the East Side of Manhattan in New York City. The avenue carries southbound one-way traffic from East 131st Street to Gramercy Park at East 21st Street. Along its 5.5-mile (8.9-kilometer), 110-block route, Lexington Avenue runs through Harlem, Carnegie Hill, the Upper East Side, Midtown, and Murray Hill to a point of origin that is centered on Gramercy Park. South of Gramercy Park, the axis continues as Irving Place from 20th Street to East 14th Street.

It is designed to carry one lane of northbound car traffic from East 33rd Street to East 40th Street.

Eighth Avenue is a major north–south avenue on the west side of Manhattan in New York City, carrying northbound traffic below 59th Street. It is one of the original avenues of the Commissioners' Plan of 1811 to run the length of Manhattan, though today the name changes twice: At 59th Street/Columbus Circle, it becomes Central Park West, where it forms the western boundary of Central Park, and north of 110th Street/Frederick Douglass Circle, it is known as Frederick Douglass Boulevard before merging onto Harlem River Drive north of 155th Street.
Tenth Avenue, known as Amsterdam Avenue between 59th Street and 193rd Street, is a north-south thoroughfare on the West Side of Manhattan in New York City. It carries uptown (northbound) traffic as far as West 110th Street, after which it continues as a two-way street.
Franklin D. Roosevelt East River Drive, commonly called FDR Drive for short, is a controlled-access parkway on the east side of the New York City borough of Manhattan. It starts near South and Broad Streets, just north of the Battery Park Underpass, and runs north along the East River to the 125th Street / Robert F.

South of the Triborough Bridge, the parkway continues toward lower Manhattan as FDR Drive. All of Harlem River Drive is designated New York State Route 907P (NY 907P), an unsigned reference route.
New York State Route 1A (NY 1A) was a north–south state highway mostly located within New York City. It extended for just under 18 miles (29 km) from an intersection with NY 27 near the Holland Tunnel in Lower Manhattan to an interchange with U.S. Route 1 (US 1) just north of the New York City line in the Westchester County village of Pelham Manor. In Manhattan and the South Bronx, NY 1A used several surface streets to traverse the boroughs, including a handful of one-way roads. At the Bronx River, it began to follow limited-access highways, specifically the Bruckner Expressway and the Hutchinson River Parkway.
The First and Second Avenues Line, also known as the Second Avenue Line, is a bus line in Manhattan, New York City, running mostly along Second Avenue from Lower Manhattan to East Harlem. Originally a streetcar line along Second Avenue, it is now the M15 bus route, the busiest bus route in the city and United States, carrying 16.4 million riders annually.

The Eighth Avenue Line is a public transit line in Manhattan, New York City, running mostly along Eighth Avenue from Lower Manhattan to Harlem.

The M10 bus now only runs north of 57th Street, and the M20 runs south of 66th Street. The whole line was a single route, the M10, until 2000 when the M20 was created.
The Broadway Line is a surface transit line in Manhattan, New York City, running mainly along 42nd Street and Broadway from Murray Hill to Harlem. Formerly a streetcar line operated by the Third Avenue Railway, it is now the M104 bus route operated by the New York City Transit Authority, a subsidiary of the Metropolitan Transportation Authority. This bus route no longer runs along the entire route of the former streetcar.
Since 1963, New York City has been using a system of bus lanes that are intended to give priority to buses, which contain more occupants than passenger and commercial vehicles. Most of these lanes are restricted to buses only at certain days and times, but some bus lanes are restricted 24/7. As of May 2021, there are 138.4 miles (222.7 km) of bus lanes within New York City.
The Second Avenue Subway, a New York City Subway line that runs under Second Avenue on the East Side of Manhattan, has been proposed since 1920; the first phase of the line did not open until 2017. Up until the 1960s, many distinct plans for the Second Avenue subway line were never carried out, though small segments were built in the 1970s. The complex reasons for these delays are why the line is sometimes called "the line that time forgot".
