Polytechnic played a leadership role in bringing about MetroTech Center, one of the largest urban university-corporate parks in the world and the largest in the United States. Today, the 16-acre, $1-billion complex is home to the University and several technology- dependent companies, including KeySpan Energy, Empire Blue Cross/Blue Shield, Bear Stearns and Company, Securities Industries Automation Corporation, New York City Police Department’s 911 Center, New York City Fire Department Headquarters and the U.S. technology and operations functions of JPMorgan Chase. In 1998, a Marriott Hotel was built adjacent to MetroTech. MetroTech has proven to be a case study in university, corporate, government and private- developer cooperation,and has resulted in renewing an area that once had been a site of urban decay.
