Remarkable advances have been achieved in the construction of the Adif Alta Velocidad’s second section of the 437km High-Speed Line Madrid-Extremadura with 69km length. Connecting Talayuela and Plasencia, this line comprises of seven subsections: Talayuela-Arroyo de Santa María (8.5 km, work completed), Arroyo de Santa María-Navalmoral de la Mata (6.8 km, works in progress), Navalmoral de la Mata-Casatejada (10.6 km, work completed), Casatejada-Toril (9.4 km, works in progress), Toril-Río Tiétar (10.7 km, works in progress), Río Tiétar-Malpartida de Plasencia (11.7 km, works in progress) as well as Malpartida de Plasencia-Estacion de Plasencia/Fuentidueñas (10.38 km, works in progress).
As one of the longest on the route and part of the Malpartida de Plasencia -Estacion de Plasencia/Fuentiduenas (Caceres)subsection, the digging process of the Dehesa del Terzuelo tunnel has been started by Adif Alta Velocidad at the early February, while it is currently under construction with an investment of about EUR70 million.
With 1.5km length and a 90 m2 section, the monotube bi-track tunnel is due to have sidewalks for evacuation and an emergency exit. Meanwhile, the used method for building of this tunnel is slated to be the new Austrian method.
