This new bidding process seeks to consolidate Route 57 as a strategic corridor between Santiago, Valparaíso, and Los Libertadores Pass, with investments of approximately USD 946 million and projects that envision long-term road improvements.
The Ministry of Public Works (MOP), through the General Directorate of Concessions, published in the Official Gazette the bidding call for the Second Concession of Route 57 Santiago – Colina – Los Andes, one of the arteries that form the backbone of transportation between the Metropolitan Region and the Valparaíso Region. This initiative contemplates an estimated investment of approximately UF 23,893,000, equivalent to approximately USD 946.2 million, with a contractual term of 49 years (588 months).
The project extends along approximately 116 km, covering territories of Quilicura, Huechuraba, Colina, Tiltil, Rinconada, Calle Larga, and Los Andes, and aims to consolidate a modern, safer, and more efficient route for passenger and freight traffic.
Project Scope and Main Works
The works under consideration include:
- Third-lane expansions in sectors with higher demand.
- New tunnel in the Chacabuco sector and rehabilitation of the existing one.
- Improvements in urban and cross-sectional connectivity, along with paving of service roads.
- New pedestrian crossings and bike lanes, aimed at improving road safety.
- Installation of electronic toll gantries along the corridor.
Additionally, the project contemplates the upgrading of existing infrastructure and the creation of new connection corridors with Route 5 and the Los Andes Inland Port, with the objective of optimizing logistical and commercial flows.
Timeline and Concession Projection
The bidding process officially began on November 27, 2025, with the receipt of technical and economic proposals scheduled for July 21, 2026, and opening scheduled for August 18, 2026. According to the official timeline, construction is expected to begin in 2031, with operational commencement projected for 2034.
The renewed concession will replace the current contract—which concludes in January 2027—and seeks to address the high traffic volumes recorded on this route. This route is essential for commercial exchange with Argentina through the Los Libertadores Border Complex, and its renewal contributes to strengthening interregional mobility.
With this new call, the MOP advances its road infrastructure agenda, incorporating an initiative aimed at improving service standards, safety, and connectivity on a corridor critical to national development.
