State P3 Legislation

The map below identifies the 33 U.S. States, District of Columbia, and one U.S. territory that have enacted statutes that enable the use of various P3 approaches for the development of transportation infrastructure.

The National Conference of State Legislatures (NCSL) has prepared an analysis of states' enabling statutes as part of its Public-Private Partnerships for Transportation: A Toolkit for Legislatures, published in December 2010.

  • Appendix B of the P3 Toolkit is a table that provides references to state statutes, provisions of the enabling legislation, and an indication of whether legislative approval is required of the P3.
  • An update to the Toolkit was released in May 2015 describing the enabling provisions for Connecticut, Maryland, North Dakota, Ohio, Pennsylvania, and the District of Columbia which are not included in Appendix B of the original report.

NCSL's Public-Private Partnerships for Transportation: Categorization and Analysis of State Statutes, published in 2016, builds on the toolkit by categorizing and analyzing all P3 enabling state statutes. The report provides an overview of nearly 40 key elements of P3 enabling legislation and breaks down each state's laws to demonstrate which key provisions are included.
