 Although the numbered streets begin just north of East Houston Street in the East Village, they generally do not extend west into Greenwich Village, which already had established, named streets when the grid plan was laid out by the Commissioners' Plan of 1811.Some streets in that area that do continue farther west change direction before reaching the Hudson River.The highest numbered street on Manhattan Island is 220th Street, but Marble Hill is also within the borough of Manhattan, so the highest street number in the borough is 228th Street.
