Public-private partnerships (PPPs) are contractual agreements formed between a public agency and a private sector entity that allow for greater private sector participation in the delivery and financing of transportation projects. 

This section of the FHWA PPP website identifies and defines some of the more common types of PPP arrangements. There are many different PPP structures, and the degree to which the private sector assumes responsibility – including financial risk – differs from one application to another.  Additionally, different types of PPPs lend themselves to the development of new facilities and others to the operation or expansion of existing assets.

These relationships are depicted in the diagram above.  Select any PPP option from the diagram to learn about distribution of roles and responsibilities between the public and private sectors for that specific PPP option.
