Breakthrough at Santiago's Linea 4

In May 12, Chile's President Lagos Escobar, with a large crowd of officials and workers, celebrated the breakthrough of the tunnels between Pique Villagra and Plaza Egana Station of Metro's Linea 4.

This marks a significant step toward the completion of Linea 4, which will connect the current three lines 1, 2 and 5. The extensions of existing lines and the construction of the new Line 4 will bring rail service to additional 1.8 million people of Santiago's five million inhabitants.

The Dr. G. Sauer Corporation (DSC) is providing design and construction support services at the underground portions of the V. McKenna to Puente Alto Section of Line 4.  Experienced NATM supervisors and engineers are on site to ensure the implementation and execution of the design intent.

The image to the right shows the recently completed Station Cumming along the Line 5 Extension which was inaugurated on 31 March 2004.  Operations on Line 2 South Extension to Station LaCisterna, where DSC also provided design and construction support will begin by December 2004.

Santiago Metro continues to deliver their projects at an impressive pace in a highly competitive environment!
