Mayor Michael Bloomberg announced this week the return and expansion of the Summer Streets program along with more than 1,500 free events taking place throughout New York City this summer. The mayor was joined by DOT Commissioner Janette Sadik-Khan, who noted that some 50,000 people enjoyed Summer Streets each time it was held last year, and that temporary car-free streets were spreading this year to 14 locations across all five boroughs. Among some of the others supporting the mayor’s announcement were Parks Commissioner Adrian Benepe, Assemblyman Joseph Lentol, Def Jam record label co-founder Russell Simmons and actor Luis Guzmán.
