Constructions on this section began in 2008, ending in May 2009. It's distance is 14 kilometers and implies the improvement of the track, in the four existing lanes (two for each direction) and the extension to six in the section between the exchanges of Circunvalación and Multiplaza.
According to the Concession Agreement, this is a new section of 38 km, which was inaugurated in January 2010.
