The works consist in the construction of second carriageways, the replacement and restoration of pavement and crossings and connections though under and over passes.
The project's importance lies, on the one hand, with improving the city of Calama's urban infrastructure and providing the city with more expedite and safer access roads for users. On the other hand, it will facilitate the transportation of copper from the mines of this part of the country, such as Chuquicamanta, the largest open pit mine in the world.
With a total length of 136.5 km, the concession consists of Route 25 and the new ring road of Calama, allowing traffic connection from this mining area of the country to Route 5, which crosses the Andean country from north to south. Route 25 will become a double lane road and will be continued on the new Eastern link of this important mining city, which involves a 25.5 km long additional single carriageway road. The project includes service roads, a link road to Sierra Gorda, several intersections, flyovers, a toll station, an emergency service area, pedestrian ways, as well as drainage, signalling and road safety works.
The revenue to finance the project will come from the tolls and state subsidies. The concession, for a maximum period of 35 years, is located in the Antofagasta Region, the second region in Chile and the most dynamic area in the country and it is expected to begin in year 2017.
