 It originates at the intersection of Reade Street and Centre Street, one block north of Chambers Street.

 A buffered bike lane runs outside of the left traffic lane.

Nolita, sometimes written as NoLIta, and deriving from "North of Little Italy" is a neighborhood in the borough of Manhattan in New York City.

 It lies east of SoHo, south of NoHo, west of the Lower East Side, and north of Little Italy and Chinatown.
The Astor Place Riot occurred on May 10, 1849, at the now-demolished Astor Opera House in Manhattan, New York City and left at least 25 dead and more than 120 injured.
 It was the deadliest to that date of a number of civic disturbances in New York City which generally pitted immigrants and nativists against each other, or together against the upper classes who controlled the city's police and the state militia.
The Astor Place Theatre is an off-Broadway house located at 434 Lafayette Street in the NoHo section of Manhattan.
 The theater is located in the historic Colonnade Row, originally constructed in 1831 as a series of nine connected buildings, of which only four remain.
 Though it bears the same name, it was not the site of the Astor Place Riot of 1849.
The Robbins & Appleton Building is a historic building located at 1-5 Bond Street between Broadway and Lafayette Street in the NoHo district of Manhattan, New York City.
 It was built in 1879-1880, and was designed by architect Stephen Decatur Hatch in the Second Empire style.
 The building features an ornate cast iron facade and mansard roof and was originally used for the manufacture of watch cases, and by publisher D. Appleton & Company.
 It was converted in 1986 to residential use.
 The building next door, at 7-9 Bond Street, is an inferior imitation of its neighbor.
Colonnade Row, also known as LaGrange Terrace, on present-day Lafayette Street in New York City's NoHo neighborhood, is a landmarked series of Greek revival buildings originally built in the early 1830s.
 They are believed to have been built by Seth Geer, although the project has been attributed to a number of other architects.
 The buildings' original name comes from the Marquis de Lafayette's estate in France, but the series of nine row houses, of which four remain, owe their existence to John Jacob Astor, who bought the property and whose grandson John Jacob Astor III later lived at No. 424.
 The buildings are listed on the National Register of Historic Places under the name LaGrange Terrace and the facades remain standing on Lafayette Street south of Astor Place.
The Bayard–Condict Building at 65 Bleecker Street between Broadway and Lafayette Street, at the head of Crosby Street in the NoHo neighbourhood of Manhattan, New York City is the only work of architect Louis Sullivan in New York City.
 It was built between 1897 and 1899 in the Chicago School style; the associate architect was Lyndon P. Smith.
 The building was originally known as the Condict Building before being renamed the Bayard Building.
 The building was considered to be a radical design for its time, since it contravened the strictures of American Renaissance architecture which were the accepted "status quo", but had little influence on architectural design in New York City, because of its location in the industrial area that Bleecker Street was during that period.
 It is located in the NoHo Historic District.
Astor Place is a short, two-block street in NoHo/East Village, in the lower part of the New York City borough of Manhattan.
 It runs from Broadway in the west, just below East 8th Street; through Lafayette Street, past Cooper Square and Fourth Avenue; and ends at Third Avenue, continuing as St. Mark's Place.
 It borders two plazas at the intersection with Cooper Square, Lafayette Street, Fourth Avenue, and Eighth Street – Alamo Plaza and Astor Place Station Plaza.
 "Astor Place" is also sometimes used for the neighborhood around the street.
 It was named for John Jacob Astor (at one time the richest person in the United States), soon after his death in 1848.
 A $16 million reconstruction to implement a redesign of Astor Place began in 2013.
