2nd Concession Route 57 Santiago - Colina - Los Andes

The project consists of a new concession of Route 57 CH, which links Santiago, in the Metropolitan Region, and Route 60 CH to the east of the city of Los Andes, in the Valparaiso Region. With an extension of 117.1 km, the current concession includes three branches: Auco-San Felipe (Route E-899), Chacabuco-Polpaico (Route G 71) and San José-Lo Pinto (Route G 73). The initiative contemplates the expansion and improvement of the existing route. Among the planned works are also the expansion to double tracks or third tracks in some sectors, the improvement of transverse connectivity especially in the urban metropolitan radius, the improvement and continuity of service roads, the construction of new service roads, service areas, bike paths and footbridges with their respective stops. It also considers the improvement of links, the revision of the connection axes with Route 5, their improvement and the projection of a new axis to replace some of the existing ones if necessary; and the construction of a new Chacabuco Tunnel. The work will improve connectivity between the mountain range and the coast, generating an expeditious route for commercial traffic, since it connects with Route 60 CH and the Los Libertadores Border Complex.
