National Route 158 is a highway in Argentina, which is located in the center-east of the province of Córdoba. From the junction with National Route 19 in San Francisco to the junction with National Route 36 in Río Cuarto, it travels 285km (177miles).
This road is part of the Mercosur-Chile Corridor, defined by IIRSA as one of the three integration axes in Argentina.[1]
Formerly,[2] this road was Provincial Route 1. By means of an agreement made on 19 October 1976, this route passed into national jurisdiction. In 2012, National Route 19 was built as an extension, which begins at National Route 11 and ends at National Route 158. With the incorporation of the new section, new roads were opened for 118.5km (73.6miles).[3]
