Project Description

The viaduct is one of the main structures which had to be builded for the High-Speed railway link between Madrid and the cities of Segovia and Valladolid. The viaduct is supported by 25 piles and the key of a central arch. It has a total length of 1755 m, with a typical span of 66 m and a central span of 132 m. It crosses a highly protected area close to the mountains in the province of Madrid and is surrounded by a special variety of oak trees.

The main central span of 132 m is the biggest in Spain and the third of its kind in the world. The arch solution is highly effective for multi-span railway bridges: the key works as a virtual abutment that enables transmission of braking forces to the foundations.

The arch was constructed in two halves that were erected vertically close to an adjacent pile onto a hinged articulation. These segments had to be lowered into position before closing the key segment with a final pour that included a pile segment.
