New boring in the Santiago de Chile metro works.
On 17 February our colleagues working on the Santiago Subway in Chile made the breakthrough for the Hernán Cortés tunnel in Section 3 with the Inés de Suárez tunnel in Section 4, and the breakthrough for the Estadio Nacional-Marathón Oriente tunnel, also in Section 3.
This latest achievement leaves just 125 m still to be excavated in order to complete the 4,700 m of tunnel between stations in Section 3.
The Pantalón has also been finished in record time (final deadline agreed with Subway 3-06-2015).
