Once the LaGuardia Airport Central Terminal agreement is signed in a few months, the board of the Port Authority of New York and New Jersey will have approved $4 billion in P3s during the past two years, more than any other U.S. transportation agency during that time.

At $2.45 billion, the LaGuardia project will be the largest capital project under construction by the Port Authority. That and the $1.5-billion Goethals Bridge DBFOM agreement,  signed in November 2013 with Macquarie and Kiewit, have whet the Port Authority’s appetite for more P3s.
