National Route 12 (Argentina) - Old Roadbed

Old Roadbed

Originally National Route 12 had a different layout through the provinces of Buenos Aires, Entre Ríos and Corrientes.

The original road started in Buenos Aires, passing through General Pacheco, Campana and Zárate. The section between Zárate's port and Puerto Constanza, in Entre Ríos Province, crossed the Paraná river by barge in a 3-hour crossing.

After the change of route of National Route 9, in the late 1950s, the section from Avenida General Paz and Campana was change to RN12. In 2005 the 8 km section between National Route 9 in Campana and the Bartolomé Mitre bridge access over the Paraná de las Palmas river changed to Buenos Aires provincial jurisdiction as a new section of Provincial Route 6. RN12 runs over the ol roadbed of National Route 193 to the bridge over National Route 9 in Zárate.

After Ceibas it followed the present National Route 14, traversing near Gualeguaychú, and the present Provincial Route 20, passing through Urdinarrain, Basavilbaso, Villaguay, Federal (Entre Ríos province) and San José de Feliciano.

In Corrientes Province, the road continued through Provincial Route 23 passing by Sauce and Perugorría, then by the present Provincial Route 24 until the junction with the present National Route 12.

This 580 km (360 mi) old roadbed changed to federal control by National Decree 1595 of 1979 except the National Route 14 section between Ceibas and the junction with Provincial Route 20.

ON the new roadbed the section between General Galarza and Nogoyá, on the south of Entre Ríos Province was still unopened. In 2005, the Dirección Nacional de Vialidad signed an agreement with its provincial counterpart to receive transfer of sections of provincial routes 6 and 39 to complete the missing sections of RN12.
