While it remains to be seen whether P3s can play a significant role in the future of U.S. infrastructure finance, state officials can and should be doing what they can to determine if P3s are right for their state and their transportation assets. In doing so, it's important for them to weigh all the potential benefits and trade-offs mentioned elsewhere in this brief, to consider the experiences-both successes and failures-of other states and indeed other countries with P3s, and to make the right choices to protect the public interest. Investment of private capital, should it be available and warranted, can be an important tool in meeting state transportation needs.
