Concessionaire company in charge of the administrative concession, operation and maintenance of the San Cristóbal Tunnel under a toll system. It consists of a system of two parallel road tunnels that cross the Metropolitan Park of Santiago de Chile in a north-south direction and serves to connect the Américo Vespucio Norte Highway (from Avda. El Salto) with the intersection of Avda. El Cerro, with Los Conquistadores and with the Lo Saldes bridge (at Kennedy). Its almost 4 kilometers in length (including both directions), 2 free flow gantries and all the systems installed in the tunnel make this route the optimal one in terms of safety and travel times.
