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" ("road corridors").

In 1990 the "Servicios de Mantenimiento de Carreteras" (Semacar) 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 Blancamarker, with tolls collected in Cañuelasmarker (km marker 78), Azul (km marker 263) and Tres Arroyosmarker (km marker 523).,

In 2003 the concession contracts expired, which lead 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.
