Santiago Metro is already working on the construction of Line 7. In Balmaceda Park, in Providencia, the company is making excavations that can barely be seen through the millimeter spaces between the panels that surround them. "This work facility corresponds to: Soil Mechanics Study of Future Line 7," says a sign on one of them that also has a warning to calm people's anxiety: "This is not the beginning of construction works of Meter. It is not the point where a station will be definitively located. "It is not an expropriation or unauthorized occupation of land."

«In Balmaceda Park, Providencia, archaeological pits are being carried out, which aim to raise and advance potential finds in the construction pits. These drillings have an approximate depth of 5 meters and are directed by an archaeologist," Metro explains in a statement.

The pit is an excavation of a small well, to observe a terrain and analyze, in this case, what difficulties it has for the construction of a tunnel. During the 18th century, Santiago built Tajamares to contain the Mapocho and in 1977 the workers building Line 1 found one of these works precisely under the Balmaceda bridge.

«A few months ago, along the entire route of Line 7, we have been developing pits or exploration drillings, which aim to define the geotechnical properties of the soils to be excavated. This way we can define the strata of the terrain through which the new line will pass. Likewise, archaeological drillings are also carried out, which seek to survey and advance potential discoveries in the construction pits," explains the manager of the Metro Projects Division, Felipe Bravo.

Mankuk is carrying out the archaeological surveys mentioned in this El Mercurio article of the Line 7 construction pits.
