Milestones:
The Dirección Provincial de Vialidad (Provincial Dept. of Transportation) has the concession to manage and maintain this road. In 2002 it installed the toll booths in Fachinal.
Before 1979 there was another road with this number in the province. It went from Santa Ana to the small town of Santa Rita, crossing through the town of Oberá, shown in green on the map. Federal Law #23153 of 9 November 1984 transferred jurisdiction of the road to the federal government and renamed it as National Route 103, as another route already had the number 105 on the west side of Misiones Province. It was transferred back to the province in 1993 and is today part of route 103. The paving of the section between Oberá and Alba Posse was done after the transfer.
