Early women from Calera de Tango were entertained by the 8M – El Amanecer de lo Herrera

CALERA DE TANGO.- The Government of Chile, through the Ministry of Public Works, published today in the Official Gazette the tender for the Orbital Santiago Sur, a highway that will give the capital a new loop beyond Américo Vespucio. The road will cross the communes of Peñaflor, Calera de Tango and San Bernardo, and will join the South Access to Santiago (Route 79) at the height of the Maipo River with Route 5, continuing west to the Autopista del Sol (Route 78). ).

The information did not sit well with the social organizations that have fought to improve the project, denying that citizen participation has taken place. “They were all citizen notifications with the appearance of participation, in which there was never a real desire for the project to be agreed upon. It was an imposition from the beginning. In the meetings with the MOP they only agreed to make small improvements, but they never had the courage to substantially improve the project so that it could be accepted by all citizens,” a source told El Amanecer de Lo Herrera.

“Putting this project out to tender a week after leaving the portfolio and handing over the government constitutes unparalleled cowardice. They will not take responsibility for the enormous damage that this new business project will cause to our communities. We call on the Regional Government to oppose this bad project, which will destroy the rurality of our communes, which constitutes an environmental aberration”, added the source.

“We want to echo the pain and anguish of so many neighbors who will lose their homes, their properties and their sources of work and livelihood, to privilege the displacement of trucks transporting merchandise produced in other areas of the country and abroad. The ones they produce today will no longer exist. They can never be produced again. Their homes will lie under the concrete of the new highway”, he completed.


The highway will have an approximate length of 24 kilometers and two lanes in each direction, making it possible to decongest consolidated urban areas, raising safety conditions, technical standards and service levels. According to previous estimates by the Ministry of Public Works, this initiative considers an investment of around US$500 million.

It also considers the construction of a two-lane highway, with Project speeds between 100 and 120 km/h, and its layout runs from Route 79 (Southern Access to Santiago) at the height of the Maipo River, bordering the north bank of the same, incorporating a new connection with Ruta 5.

Immediately after, it crosses Route 5 and the railway line through an overpass, continuing towards the west until it connects with Route 78 (Santiago-San Antonio Highway) through a link. In the section between Route 5 and Route 78 (Santiago – San Antonio Highway), the project continues parallel to the south of the current Calera de Tango road, avoiding a strongly consolidated area.
