For the construction of the Potrerillos dam in the province of Mendoza. The dam was built between 1999 and 2003 by a consortium consisting of Industrias Metalúrgicas Pescarmona (IMPSA) to provide flood control, hydroelectricity and irrigation water.The main problem was that in order to build the dam it was necessary to interrupt route 82. This route connected the cities of the region, like Potrerillos and Cacheuta. Once the construction of the dam was finished, work began on the reconstruction of route 82 in order to restore the connection between Potrerillos and Cacheuta. The trace of route 82 was also redesigned to generate a tourist path in the perimeter of the lake (reservoir).
