Sierra Flor

Ausgangslage

The road concession, Autopistas de la Sabana, is responsible for link 3 departments of Colombia, starting from Cordoba to Bolivar. Passing the capital of the department of Sucre, (Sincelejo) is the mountainous area of the project, called Sierra Flor. For the construction of the double lane, it was necessary to cut a lot of material on the slope that left the material exposed to erosive factors like wind and water, generating small instabilities that must be controlled.
