On this morning's Brian Lehrer Show: Happy 200th anniversary, Manhattan street grid! Tune in around 11:40am to hear Joel Towers, executive dean of Parsons The New School for Design, talk about the anniversary of the grid layout of streets in Manhattan. (For the NYC area, that's AM820 and FM 93.9. For everyone else, the show streams online at wnyc.org.)
For more on how the grid was built -- way back when Houston Street was called North Street -- listen here to a WNYC interview with New York University professor Hilary Ballon, who's curating an upcoming exhibit on the street design.
