For those moments the famous stone continued to provide its bridge service even though the step was made from, jump to jump; because the swamps prevented the passage on the other side, for this reason, this swampy and uninhabited area took the name of "Puente Piedra" in Republican times and when the haciendas required a greater number of workers for cotton and sugar cane crops.

The inhabitants confront Tomás Marsano through a judicial process, taking refuge in the possession of the land, which with great effort they managed to put at the service of agriculture.

In 1922, during the second government of Augusto B. Leguía, the struggle achieved the most resounding triumph: the expropriation law of the Puente Piedra land was promulgated, declaring those who currently own it the owners.

In this way, the Carabayllo District loses its most important homestead, the maritime strip of Ventanilla, the train station, the sugar mill and various haciendas.

After the 'boom' of private and foreign investment in Independencia, San Martin de Porres, Los Olivos and Comas, the Puente Piedra district is now added.
