In 1990 administration and maintenance of the most travelled roads was given to private companies with rights to collect tolls dividing the areas in "Corredores Viales". "Servicios de Mantenimiento de Carreteras" company, took charge of Corridor number 1, which includes Route 3 between km markers 19 and 677, in Buenos Aires Province, from the joining with Provincial Route 4 in San Justo to Bahía Blanca, with tolls collected in Cañuelas, Azul and Tres Arroyos.,
In 2003 the concession contracts expired, which led to a modification of corridor numbers and a call for a new public bid. Corridor Vial number 1 is now given to "Empresa Rutas al Sur" and runs from km marker 62 to 677 which corresponds to the crossing of Provincial Route 6 in Cañuelas until it joins National Route 252 in Grünbein.
