Delancey Street is one of the main thoroughfares of New York City's Lower East Side in Manhattan, running from the street's western terminus at the Bowery to its eastern end at FDR Drive, connecting to the Williamsburg Bridge and Brooklyn at Clinton Street. It is an eight-lane, median-divided street west of Clinton Street, and a service road for the Williamsburg Bridge east of Clinton Street. West of Bowery, Delancey Street becomes Kenmare Street, which continues as a four-lane, undivided street to Lafayette Street.
Delancey Street is named after James De Lancey, Sr., whose farm was located in what is now the Lower East Side.
Businesses range from delis to check-cashing stores to bars. Delancey Street has long been known for its discount and bargain clothing stores. Famous establishments include the Bowery Ballroom, built in 1929, Ratner's kosher restaurant, and the Essex Street Market, which was built by Mayor Fiorello La Guardia to avoid pushcart congestion on the neighborhood's narrow streets. Until the middle 20th century, Delancey Street was a main shopping street in the predominantly Jewish Lower East Side.
