The Eighth and Ninth Streets Crosstown is a public transit line in Manhattan, New York City, running mostly along Eighth Street, Ninth Street, Tenth Street, and Christopher Street through the West Village, Greenwich Village, and East Village. Originally a streetcar line, it is now the M8 bus route, operated by the New York City Transit Authority. Route description The M8 begins at the intersection of Christopher and West Streets, on the west side of Manhattan. From West Street to Greenwich Avenue, the bus runs west along Christopher Street and east along West 10th Street. At Greenwich Avenue, the bus runs west along West 9th Street and east along West 8th Street. These become East 9th and East 8th Streets, respectively, east of Fifth Avenue (east of Third Avenue, East 8th Street is known as St. Mark's Place). At Avenue A, both directions cross over to East 10th Street to avoid Tompkins Square Park. The route terminates on East 10th Street, just east of Avenue D.

The one-way pair continued to Greenwich Avenue, through which the Seventh Avenue Line ran; cars turned southeast on Greenwich Avenue and east on Eighth Street along the Seventh Avenue Line tracks. The Seventh Avenue Line turned south at Macdougal Street, while the Eighth Street Crosstown continued along Eighth Street to Cooper Square. There the westbound track split to the northeast on Astor Place/Stuyvesant Street to reach Ninth Street, and the tracks were separated in Eighth and Ninth Streets to Avenue A. Trains turned north in Avenue A for two blocks (eastbound) or one block (westbound), along Forty-Second Street and Grand Street Ferry Railroad trackage, to Tenth Street, and then turned east again for the rest of the line to the East River.
