Already in the 20th century, the town became the starting point of the so-called Plan Sur, which involved the diversion of the river Turia after the tragic flood of 1957 with the objective of not traversing Valencia. For his area runs A-3 highway that connects Valencia and Madrid, which has led the development of one of the most important industrial areas of the province and a major population change. If in the early 1960s, Quart de Poblet had little more than five thousand inhabitants, ten years after the arrival of people, mainly from Andalusia, Murcia, Aragon and Castilla-La Mancha, whose work and contributions have enriched culturally and economically the town, fired that figure and stood at nearly 26,000 current residents.
