In a move that is certain to change the activity patterns of hundreds, if not thousands, of Park Slope children, parents and nannies, the Third Street Playground is closing for long-planned renovations tomorrow. The renovated playground will have new safety surfaces, improved drainage and new water features. The work was actually originally planned for spring and summer; it is expected to be completed in late fall or early winter. The playground is near the Third Street & Prospect Park West entrance to the park.

The playground is one of a number in the park getting overhauls. Renovations were recently completed at the Parade Ground Playground, which is at the corner of Coney Island Avenue and Parade Place near E. 16th Street. A redesign of the Vanderbilt Street Playground, which is located at the Vanderbilt Street & Prospect Park SW entrance is currently in the design stage.
