Overview

AUBASA — Autopistas de Buenos Aires S.A. — is an Argentine toll-road company owned by the Government of Buenos Aires Province. It was created in 2013 through Decree No. 409, issued on 27 June 2013, as part of an Integral Road Plan, and was registered as a company with the Provincial Directorate of Legal Persons on 5 June 2013 under registration No. 115,493. Its corporate purpose is the construction, conservation and operation of roads and motorways under a concession regime, financed through tolls in Buenos Aires Province. The company took over the administration of the Autovía de la Ruta Nacional 1, officially named Autopista Doctor Ricardo Balbín since 2004. This motorway links the 25 de Mayo motorway in the City of Buenos Aires with Provincial Route 11 near La Plata, the provincial capital. Its 50-kilometre trace runs from kilometre 3 to kilometre 53, passing through the partidos of Avellaneda, Quilmes, Berazategui and Ensenada near the Río de la Plata. At kilometre 31 it connects with the A004, the obligatory route for tourist destinations such as Mar del Plata and other Atlantic coast cities. The motorway has two main toll stations, one at Dock Sud and another at Hudson. AUBASA's creation followed the rescission of the concession previously held by the company Coviares, which had been under intervention since February 2013 amid an investigation into contractual irregularities. The new firm was capitalised with 93% of its share package owned by the provincial state and the remaining 7% held by workers, represented by their trade union association. On 11 July 2013, through Resolution No. 278 of the Buenos Aires Ministry of Infrastructure, AUBASA effectively assumed the operation, improvement and maintenance of the Buenos Aires–La Plata motorway, committing to service continuity. On 4 December 2013, after approval by Decree No. 909/13, the province signed a 30-year concession contract with AUBASA. In 2014 the company began an integral reform plan aimed at creating the first smart motorway in Buenos Aires Province. This included replacing all road lighting with LED luminaires, expected to achieve 40% energy savings, and inaugurating a Monitoring Centre in Hudson with 180 security cameras along 70 kilometres, connected directly to municipalities, road safety patrols, Civil Defence and emergency services. On 1 December 2016, AUBASA took charge of the operation, maintenance and works plan of the so-called "Atlantic Road Corridor", comprising Autovía 2 and routes 11, 56, 63 and 74. Today AUBASA operates as a provincial state-owned enterprise, managing toll collection, electronic invoicing, the TelePASE electronic toll system, road safety campaigns and a 2024–2027 Works Plan. Its official website provides a 24-hour assistance line (140), tariff tables, claim and suggestion channels, and news on works such as the repaving of the entire Autovía Provincial 2, the new City Bell access, the Diagonal 74 access and the new Operations Centre.

History

AUBASA was created in 2013 as part of a provincial effort to restructure road concessions in Buenos Aires Province. On 11 July 2013, the Government of Buenos Aires Province, through Decree No. 409/13, rescinded the concession held by the company Coviares, which had been under intervention since February of that year amid an investigation into contractual irregularities. The province then decided to create AUBASA to take charge of administration and maintenance. The new firm was capitalised with 93% of its share package owned by the provincial state and the remaining 7% held by workers, represented by their trade union association. It was registered as a company on 5 June 2013 under registration No. 115,493. AUBASA's corporate purpose is the construction, conservation and operation of roads and motorways under a concession regime through the collection of tolls in Buenos Aires Province. On 11 July 2013, by Resolution No. 278 of the Buenos Aires Ministry of Infrastructure, AUBASA effectively assumed the operation, improvement and maintenance of the Buenos Aires–La Plata motorway, committing to service continuity. On 4 December 2013, following approval by Decree No. 909/13, the province signed a 30-year concession contract with AUBASA, setting out the rights and obligations of each party. The motorway it administers, the Autovía de la Ruta Nacional 1, has been officially named Autopista Doctor Ricardo Balbín since 2004. It links the 25 de Mayo motorway in the City of Buenos Aires with Provincial Route 11 near La Plata. Its 50-kilometre trace runs from kilometre 3 to kilometre 53, passing through Avellaneda, Quilmes, Berazategui and Ensenada near the Río de la Plata. At kilometre 31 it connects with the A004, the obligatory route for tourist destinations such as Mar del Plata and other Atlantic coast cities. The motorway has two main toll stations, at Dock Sud and Hudson. In 2014 AUBASA began an integral reform plan to create the first smart motorway in Buenos Aires Province. This included replacing all road lighting with LED luminaires, expected to achieve 40% energy savings, and inaugurating a Monitoring Centre in Hudson with 180 security cameras along 70 kilometres, connected directly to municipalities, road safety patrols, Civil Defence and emergency services. On 1 December 2016, the company took charge of the operation, maintenance and works plan of the "Atlantic Road Corridor", comprising Autovía 2 and routes 11, 56, 63 and 74. In recent years AUBASA has continued to invest in road safety and infrastructure. Its website highlights a 2024–2027 Works Plan, the repaving of the entire Autovía Provincial 2 to be completed by 2027, the construction of a new City Bell access and a new Diagonal 74 access, the inauguration of a new Operations Centre, a tree restitution plan, participation in the V National Road Safety Congress, operational drills, and measures such as prohibiting metal "fish tail" terminals in its works and sanctioning toll evasion on the Buenos Aires–La Plata motorway from 15 September.
