Provincial Route 11 (also named "Interbalnearia" after its new path was completed in 1979)Todos los caminos conducen a la discordia by Carlos Cúneo on Siete Días Ilustrados, 31 May 1971De La Plata a Miramar on Larutanatural.gob.ar is a Argentine road in the East of Buenos Aires Province. The road extends from Punta Lara (starting in the junction with PR 19) to the town of Mar del Sur."Nuestras Rutas", Dirección de Vialidad de la Provincia de Buenos Aires

Route 11 runs along the coasts of the Río de la Plata and the Atlantic Ocean, with a high number of cars passing the road during summertime. The path between Magdalena and the intersection with Provincial Route 36 is still a gravel road so the route has not been paved to date. On the other hand, from the crossing with Provincial Route 63 (popularly known as Esquina de Crotto)"La pulpería que sobrevive en el tiempo", La Nación, 2000-07-10 to the town of General Conesa, the route becomes a dual carriageway, totalizing 30 km with two carriages per way. The stretch between Pinamar and Villa Gesell the route becomes a dual carriageway again.

This road contributed to development of the cities situated on the Buenos Aires Province coast at the Nort of Mar del Plata, due to the only town of the region reached by railway was Pinamar. The train that departed from General Guido until its terminus in Divisadero de Pinamar (a branch-line of General Roca Railway from Buenos Aires to Mar del Plata) operated from 1949 to 1968, being reestablished in December 1996;Partido de Pinamar, Heráldica Argentina "El fondo de campo que llegó a ser centro turístico", María Cristina Coccari although in April 2015, it was closed again, remaining inactive to date."Estado de los Trenes a Pinamar", Satélite Ferroviario website

History

The beginning The first works on the road were made in the zone of Mar del Plata. The path between the downtown and Camet Park was paved in 1928, then followed by the pavement of the stretch to the Punta Mogotes lighthouse, finished in 1933.Cuatro años de gobierno 1936-1940, volumen IV Vialidad de la Provincia, 1940, editorial Guillermo Kraft, 1940

In 1932, the Camino de la CostaHistoria de Santa Teresita a provincial road that extended from Avellaneda to Mar del Plata along with the coasts of the Río de la Plata and the Atlantic Ocean was opened. Four years later the coast road in Punta Lara was built. Nevertheless, the Sudestada (Southeast blow) caused a flooding that destroyed most of the road. For that reason, a wall was raised to avoid floodings; nevertheless, the water was eroding the wall until in July 1958, a new swell of the river brought down the wall, destroying the "Camino Costanero" (as Route 11 was also called). The flooding not only damaged the road but about 100,000 houses were devastated by the unstoppable course of the water El Río de la Plata destruyó el Camino Costanero", Vialidad magazine #4, 1958

The paved road from Mar del Plata and Miramar was built between 1937 and 1938,Paseo Costanero Sur, Mar del Plata official website while the stretch between La Plata and Magdalena was finished in 1961."Obras terminadas en el segundo semestre de 1961", Vialidad magazine #18, 1962

In early 1970s, the Ministry of public works of Buenos Aires Province announced that there were two projects for route 11: the first included the paving of the actual road that passed through the cities of General Madariaga and Juancho, while a second alternative consisted of the construction of a new road (named "Ruta Interbalnearia") that would start in the point where the old route 11 turned to General Madariaga –near the city of General Lavalle– extending 12 kms east to San Clemente del Tuyú. The road then would run nearest to the coast, from north to south along the cities of La Costa Partido, for a total length of 62 km. The project included the build of eight entrances to those cities (the actual route 11 had only road access to San Clemente, Santa Teresita, and Mar de Ajó).

Finally, the second option was chosen, despite the protests of the General Lavalle inhabitants (specially the cattle breeders, who alleged the new road would affect their economic activities). The construction costs saving ($4 million) and the more favorable conditions to promote the development of La Costa Partido were the reasons given by the Ministry to build the Ruta Interbalnearia. A call for tender was conducted in September 1971.

When the Interbalnearia was definitely finished and inaugurated in 1979,Por qué la interbalnearia by Juanjo Lakonich on Página/12, 21 Jun 2023 some parts of the original road had changed.República Argentina, red caminera principal, Automóvil Club Argentino (1969) It has remained as a gravel road since then.Atlas de rutas Firestone Argentina, sur de Brasil, Chile, Paraguay, Uruguay, editorial Buenos Aires, 2007 -

In 1986, the Government of Buenos Aires Province transferred the stretch of the road crossing the urban area of Mar del Plata, to General Pueyrredón Partido, 1986-08-05. On December 5, 1987, the paved path from Miramar to Mar del Sur was opened to traffic

Concession On September 19, 1990, the contract of concession was signed. The management of the road was subsequently given to "Camino del Atlántico" ("Road of the Atlantic" in Spanish), which would take over the maintenance of the Route from the intersection with Provincial Route 36 to the traffic circle access to Santa Clara del Mar. The contract was for a term of 15 years, with the option to be extended to 20 years through a special clause.Documentación Ruta 11, Dirección Provincial de Vialidad The toll booths were placed in "Paraje La Huella", near General Conesa, and Mar Chiquita.

During 1996, the concessionary built a dual carriageway between the cities of Pinamar and Villa Gesell, financed by an increase of the toll rates which was made effective once the works finished."Acta acuerdo de adecuación del contrato", Dirección de Vialidad de Buenos Aires

In December 2010, a 10 km path between Santa Clara del Mar and Parque Camet was opened. The works had a cost of $43 million."Inauguración de la autovía que une Mar del Plata y Santa Clara del Mar", Secretaría de Medios de la Provincia de Buenos Aires

In July 2011, the Government of Buenos Aires trespassed the management of the Route 11 to "Autovía del Mar" for a term of 30 years. The company also manages Provincial routes Autovía 2, 63, 56, 74 and 36."Autovía del Mar es el nuevo concesionario de la Autovía 2", Notitrans, 1 July 2011 In 2016, Governor of Buenos Aires, María Eugenia Vidal revoked concessions so route 11 become state-owned again.Vidal oficializó la estatización de las rutas 2 y 11 de la Provincia, Clarín, 11 Nov 2016
