Cagancha (Figures 1 and 2)

The Talayuela-Cáceres high-speed line crosses the Cagancha stream through a 431-m long viaduct, distributed in eight central spans of 45.00 m and two lateral spans of 35.50 m.

Due to the spans that result from the fitting of the viaduct, it has been necessary to resort to a hyperstatic solution with a prestressed concrete box section executed in situ using the segmental bridge construction method.

This section has an upper width of 14.00 m that allows a 10.10 m wide double track to be housed, limited by two 0.20 m thick ballast guard walls and two 1.75 m walkways on each side.

The piers are made up of a hollow octagonal section, with 0.40 m thick walls, which is solid in the upper 3 m. All these features are shared with Villaluengo and Santa Ana viaducts.

Villaluengo (Figures 3 to 5)

The Talayuela-Cáceres high-speed line crosses the Villaluengo stream through a 431-meter-long viaduct, distributed in eight central spans of 45.00 m and two lateral spans of 35.50 m.

Santa Ana (Figures 6 to 8)

The high-speed line Talayuela-Cáceres in its section Embalse de Alcántara-Garrovillas crosses over the Santa Ana stream between pp.kk. 5 + 374,500 and 5 + 715,500 through a 341.00 m long viaduct, distributed in six central spans of 45.00 m and two lateral spans of 35.50 m.
