Breakthrough at the El Casar subway construction site (Spain)


The President of the Community of Madrid, Isabel Díaz Ayuso, attended the breakthrough of the tunnel for the extension of line 3 of Metro de Madrid, between the Villaverde Alto and El Casar fronts, which OSSA is executing together with Azvi and Cotodisa.

Currently, 2.3 km of the total 2.6 km have already been excavated, using both the traditional Madrid method and the sequential method.

This extension will connect the east arc of Metrosur with the rest of the metro network in a fast and efficient way. El Casar station will have a direct connection with L12, C3 and will have a parking which will allow connection with other modes of transport.
