This report was designed primarily to identify significant legal issues associated with the implementation of PPPs in the highway sector. The report also discusses some potential solutions to these requirements and at-tempts to draw some lessons that may in certain circumstances facilitate the implementation of highway PPPs. Many of the requirements discussed in this re-port have more than legal dimensions or could be the subject of further discussion and analysis. The objective of this report was to provide a broad overview of legal requirements and possible solutions. The report does cite to a number of sources that provide further discussion about various topics that are beyond the scope of this endeavor. This report hopefully will serve as a baseline resource for any public- or private-sector participant that wants to expand its involvement in PPPs in the highway sector.
