We built two vehicular bridges in the Puente Negro area, Colonia Dora, Santiago del Estero, to improve the quality of life for 500 people living in geographic isolation. The tanker truck that delivers potable water, as well as ambulances and other vehicles, had to travel long distances due to the lack of these bridges, which now connect the community and facilitate access. These projects were carried out with volunteer labor from local residents and students from Switzerland, France, and Australia who collaborated on the project.
