Route A-529 is the access road to the community of Parca, Mamiña and the secondary access route to BHP’s Cerro Colorado mine. Public transportation minibusses and light vehicles used by residents and tourists circulate along this route daily.
The slopes have an average height of 80 meters. As a result of the high level of fracturing and weathering of the rocks, there are constant rock falls of different sizes onto the road.
The Ministry of Public Works planned to replace and maintain the conventional rock guiding systems with DELTAX and QUAROX systems. These are easy and fast to install, thus reducing exposure time for workers and providing better resistance for large blocks.
