Opening of road to San Francisco
In 1964, the road from Tambo to the port of San Francisco on the Apurimac River was opened, accelerating the colonization of the valley by Ayacucho farmers and facilitating the economic development of the area.
The road from Tambo to the port of San Francisco was opened in 1964, accelerating the process of occupation of the valley by peasant settlers from Ayacucho. This road infrastructure allowed the important fair of Tambo, which was the end of the road, to 'drop off' towards the jungle as the road advanced until it reached the town-port of San Francisco, located on the Apurimac River. The San Francisco bridge, inaugurated later in 1971, increased the occupation of the right bank of the river, territory of the department of Cuzco where the Pichari settlement is located. This road opening was part of the economic dynamism of the Apurimac River since the middle of the 20th century, following the Huamanga/Huanta axis to Tambo.
