The project considers the construction of a highway located in the southern area of Santiago, which begins in the Acceso Sur by the north bank parallel to the Maipo River until the Route 5, then in the section between the Route 5 and the Autopista del Sol, continues parallel to the south of the current Calera de Tango road until it connects with the Route 78. The future route will create connectivity of the flows coming from the sector of Peñaflor and the Port of San Antonio, towards Route 5 and the south of Greater Santiago; improving the connectivity between Route 78 (Autopista del Sol) and Route 5 and Southern Access to Santiago. Along with this, it will generatesa new combination of exit/entry to Santiago from/to the coast via Route 78, as well as a better connection of the northwestern area of Santiago with Route 5 South from Route 78.
Preliminarily, the route considers the development of four links: Route 78, Camino Lonquén, Route 5 and Acceso Sur to Santiago, as well as three underpass crossings.
The project consists in the improvement of 218 km of Route 5, in the section between the city of Santiago and the town of Los Vilos, through extensions to third tracks that will be studied, but are planned in sectors between Lampa and the Til link and between the localities of Ocoa and El Melón, the final location will depend on what the study of demand indicates. New links, crossings, the replacement of some bridges, route corrections to leave a uniform speed of 120 km/hr (except in the Cuesta Las Chilcas and La Calavera Tunnel), new sections of service roads, pedestrian walkways, lighting, change of all retaining barriers, new service areas and the improvement and expansion of existing ones, etc. are planned. The initiative also includes the rehabilitation of the existing roadways, which will improve safety standards on the route, increase the standard of service, replace the manual toll by incorporating Free Flow system through Electronic Toll gates located at distances not exceeding 10 km.
The project consists of a dual roadway that extends for 75 km in length, from km 413.2 of Route 5 South (approximately 11 km south of Chillán) to its junction with Route 150 CH, which connects Penco with Concepción, in the Bío Bío Region. In addition, there are 14 km of branches. The initiative includes widening the road platform to give uniformity to the profile of segregated median with defenses, rehabilitate existing roads, rectify routes and enable new bridges and sections of service roads. Among the benefits of the work are the improvement of the safety standards of the route and the incorporation of electronic toll gates (free flow).
