Management
In 1990 a federal law decreed the development of the most travelled national routes by means of concessions to private companies in delineated Corredores Viales (Road Corridors). Designated Corredor Vial 18, it was given to the company that had the winning bid, Caminos del Río Uruguay S.A. (CRUSA). There are no toll booths on this route. In 1996 the concession was extended to 28 years under the condition that the winning bidder built a highway between the Zárate-Brazo Largo Bridge and Gualeguaychú. The section between the General Justo José de Urquiza Bridge and Ceibas (corresponding to National Route 12) was completed on 12 October 1999. Due to the peso devaluation in 2002, construction was stopped on the section between Gualeguaychú  and National Route 14. History
Before 1980 there was another road with this number. It was the route in the NW of Corrientes Province, marked in green on the map and now called National Route 118. Decree #1595 of 1979, ceded the previous road to the administration of Corrientes Province. Decree 1715 from 1988 annuls the previous decree and this road became National Route 118 as number 117 had been used on this road. References
