This section is an important important communication route in the most productive and densely populated region of Argentina, forming part of the highway that connects the city of Córdoba with the city of Rosario.
Four interchanges located at the entrances to the towns of General Roca, Marcos Juárez and the city of Leones were planned for the entrance and exit of the highway.
In the sectors in between the interchanges there are 4 elevated crossings to connect both sides of the highway.
In each of these, as well as in the interchanges, eight bridges, each 50 m long, have been built. In addition, the viaduct for the Leones service area was developed, which includes two 650 m long bridges, accesses, lighting and signaling works.
