Summer streets is back where the city will close down a nearly 7-mile stretch through Manhattan in celebration of what it describes as its “most valuable public space”: its roughly 6,000 miles of streets. The route, as usual, runs from East 72nd Street and down Park Avenue, Fourth Avenue, Lafayette Street and Centre Street to City Hall. The closures will take place for six hours, from 7 a.m. to 1 p.m., on Aug. 5, 12 and 19.
