The emergence of PPPs and toll-funded facilities developed through innovative project delivery approaches has enabled several countries in South America to expedite opening critical highway linkages that promote improved mobility between once isolated regions or over-congested metropolitan areas. These countries include Argentina, Brazil, Chile, Columbia, Peru, and Mexico. These expedited investments in transportation infrastructure have fostered greater economic development on a regional and national level. PPPs have become the contracting vehicles for enabling these benefits to occur in a timely manner.
