the actual construction of the rural highway started in the 2005 by the secretary of public works and communication (secretaria de publicas y comunicación, seopc). in november 2007 the highway started final paving, since the landscape is difficult and the financing has been a major issue for the project and had stalled on several occasions thus delaying the project. it was finished by early february 2008. the new highway opened on june 1, 2009, and stretches 106 kilometers at a cost of us$150 million.
