In 2006, his administration carried out 141 of the promised projects, making that year the most active in the governor's term. The 608 projects Peña Nieto proposed consisted of creating highways, building hospitals, and creating adequate water systems to provide fresh water throughout the state. The most important of these was highway infrastructure, which tripled under Peña's government. By mid-2011, the official page of the State of Mexico noted that only two projects were left. The major projects in public transportation were the Suburban Railway of the Valley of Mexico Metropolitan Area and the "Mexibús", both of which served commuters between Mexico City and the State of Mexico, providing service to more than 300,000 people every day and 100 million a year. Regarding public health services, 196 hospitals and medical centers were built throughout the state and the number of mobile units to attend remote and vulnerable areas doubled. Deaths caused by respiratory diseases were reduced by 55%, while deaths caused by dysentery and cervical cancer were reduced by 68% and 25% respectively. In addition, between 2005 and 2011, the State of Mexico was able to fulfill the requirement of the World Health Organization of having one doctor for every 1,000 inhabitants. The funds for these and all the other commitments were obtained through restructuring the state's public debt, a strategy designed by his first Secretary of Finance, Luis Videgaray Caso. The restructuring also managed to keep the debt from increasing during Peña Nieto's term because the tax base was broadened to the point that it doubled in six years.
