Introduction
Long-term public-private partnerships (P3) for transportation infrastructure are still relatively uncommon in the United States (though more widely used in Europe, Latin America, and the Asia/Pacific region). A recent policy paper lists 37 such projects that have been financed in the United States between 1993 and the end of 2022—less than two projects per year.
Although 38 states (plus Puerto Rico and the District of Columbia) have enacted P3 transportation legislation, according to the National Conference of State Legislatures, such projects have been financed and built in only 11 states (plus the Port Authority of New York & New Jersey).
