Broadway is an avenue in the New York City borough of Brooklyn that extends from the East River in the neighborhood of Williamsburg in a southeasterly direction to East New York for a length of 4.32 miles (6.95 km). It was named for the Broadway in Manhattan. The East New York terminus is a complicated intersection with East New York Avenue, Fulton Street, Jamaica Avenue, and Alabama Avenue. The BMT Jamaica Line of the New York City Subway runs on elevated tracks over Broadway from the Williamsburg Bridge to East New York on its way to Queens. Broadway forms the boundary between the neighborhoods of Bushwick, which lies above Broadway to the northeast, and Bedford–Stuyvesant, which is to the southwest.

Williamsburg is a neighborhood in the New York City borough of Brooklyn, bordered by Greenpoint to the north; Bedford–Stuyvesant to the south; Bushwick and East Williamsburg to the east; and the East River to the west. It was an independent city until 1855, when it was annexed by Brooklyn; around that time, the spelling was changed from Williamsburgh to Williamsburg.
