Highway Public-Private Partnerships: More Rigorous Up-front Analysis Could Better Secure Potential Benefits and Protect the Public Interest
Source: Government Accountability Office, GAO-08-44 February 8, 2008
Highway public-private partnerships have resulted in advantages for state and local governments, such as obtaining new facilities and value from existing facilities without using public funding. The public can potentially obtain other benefits, such as sharing risks with the private sector, more efficient operations and management of facilities, and, through the use of tolling, increased mobility and more cost effective investment decisions. There are also potential costs and trade-offs--there is no "free" money in public-private partnerships and it is likely that tolls on a privately operated highway will increase to a greater extent than they would on a publicly operated toll road. There is also the risk of tolls being set that exceed the costs of the facility, including a reasonable rate of return, should a private concessionaire gain market power because of the lack of viable travel alternatives. Highway public-private partnerships are also potentially more costly to the public than traditional procurement methods and the public sector gives up a measure of control, such as the ability to influence toll rates. Finally, as with any highway project, there are multiple stakeholders and trade-offs in protecting the public interest.
