In 1950, IRI (Institute for Industrial Reconstruction) established a company named Autostrade Concessioni e Costruzioni SpA. In 1956 Autostrade enters into agreement with ANAS to co-finance, build and operate the Autostrada del Sole between Milan and Naples. The motorway is opened in 1964. Between 1962 and 1968, the Company was granted the concession to build and operate further motorways.

Autostrade is privatised in 1999 and IRI is replaced by a stable group of shareholders led by Edizione (controlled by the Benetton family).

In 2003 the infrastructure assets operated under concession were separated from the non-motorway businesses, resulting in the establishment of Autostrade per l’Italia, currently 88.06% owned by Atlantia (then Autostrade SpA), a holding company listed on the Milan Stock Exchange.

Since 2005 Atlantia began a process of geographical diversification by acquiring the management of approximately 2,000 km of toll motorway in Brazil, Chile, India and Poland.

Atlantia entered the airport infrastructure sector in 2013  and operates the two airports of Rome (Fiumicino and Ciampino). The Group expanded its presence in the airports sector in 2016, acquiring Aéroports de la Côte d’Azur, the company that controls the airports of Nice, Cannes-Mandelieu and Saint Tropez.

With the acquisition of Abertis finalized in October 2018, Atlantia is the world leader in transport infrastructures and integrated transport-related payment systems  with approximately 15,000 km of motorways under concession and presence in 23 countries. In 2018, Atlantia acquired the 15.5% of Getlink, holding that manages the Eurotunnel in the English Channel.

Recently, throughout 2020, Atlantia though Abertis Infrastrucuras acquires the 53.1% of Red de Carreteras de Occidente in Mexico and the 55.2% of the Elizabeth River Crossing in the United States.
