Title:
List_of_numbered_streets_in_Manhattan

Context:
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 streets when the grid plan was laid out by the Commissioners' Plan of 1811. Streets that do continue farther west change direction before reaching the Hudson River. The grid covers the length of the island from 14th Street north.

Question:
Who laid out the Grid Plan?

Commissioners' Plan of 1811
