Lo Saldes Bridge Replacement in Santiago

project in construction

The project involves the complete replacement of the superstructure of the Lo Saldes Bridge in Santiago, Chile, as part of a major infrastructure modernization initiative led by the Chilean Ministry of Public Works (MOP). With an investment exceeding US$16 million, the works are aimed at restoring the bridge’s structural integrity and improving its seismic resistance after a structural failure was detected in early 2025. The intervention includes dismantling the existing bridge deck and replacing the original steel girders with new high-strength girders, reinforcing the supporting structures, upgrading the roadway system, and adapting the bridge to current engineering and safety standards. Because the bridge is a key urban connection carrying approximately 50,000 vehicles daily between Providencia, Las Condes, and Vitacura, construction is being executed in phases to maintain traffic flow and minimize disruptions during the estimated 12-month construction period.
