Public-Private Partnerships (P3)


Public private partnerships (P3s) are contractual agreements between a public agency and a private entity that allow for greater private participation in the delivery of projects. In transportation projects, this participation typically involves the private sector taking on additional project risks such as design, construction, finance, long-term operation, and traffic revenue. Learn more about P3s on FHWA’s Center for Innovative Finance Support website.

The Build America Bureau encourages the consideration of P3s in the development and delivery of transportation improvements. Early involvement of the private sector can bring innovation, efficiency, and capital to address complex transportation problems facing State and local governments. The Bureau provides information and expertise in the use of different P3 approaches and provides TIFIA and RRIF loans and Private Activity Bonds (PABs).
