There were a few interruptions in the grid for public spaces, such as the Grand Parade between 23rd Street and 33rd Street, which was the precursor to Madison Square Park, as well as four squares named Bloomingdale, Hamilton, Manhattan, and Harlem, a wholesale market complex, and a reservoir. Central Park, the massive urban greenspace in Manhattan running from Fifth Avenue to Eighth Avenue and from 59th Street to 110th Street, was not a part of the plan, as it was not envisioned until the 1850s. The numbering was also extended through Manhattan and the Bronx.
