An air traffic control tower is seen at the central terminal of LaGuardia Airport in the Queens borough of New York April 8, 2014. With constraints on its resources and no appetite for further debt, private investors and developers are being tapped to rebuild the 50-year-old central terminal for $3.6 billion, instead of using traditional public finance methods. U.S. states and cities are increasingly turning to such deals, known as public-private partnerships, or P3s, hoping to leverage assets that can bring a quick infusion of private dollars to rebuild crumbling infrastructure.
