In the 1920s, Calzada Ignacio Zarragoza was built to connect to the city center to the Puebla highway. This main road spurred the development of more subdivisions expanding the urban sprawl east. A large amount of land in this area belonged to a man named Alberto Braniff, who provided it to establish Mexico City's first private airstrip in 1909, which became the Aeropuerto Central de la Ciudad de México in 1943. In 1954, the airport relocated, expanded and was reconditioned for international flights to become the Mexico City International Airport. This airport prompted the development of warehouses, hotels, and offices in the area.
