Very little infrastructure is controlled at the national level outside of transportation (Federal Highway System), national parks, federal buildings, homeland security and the military. The United States Department of Transportation does have resources for PPPs[xxxviii] and there is also the National Council for Public-Private Partnerships, which has a database of case studies across multiple sectors and states.
While the American Recovery and Reinvestment Act (ARRA) included funding for infrastructure projects, most of that work was classified as "shovel-ready". Since PPPs generally take years to get to the contract stage, most infrastructure work under the ARRA does not include PPPs.
