In the Palanquinos region of Spain, the construction of the North–Northwest High-Speed Railway Line, on the Palencia–León section, gave rise to a major engineering project. Forming part of one of the country’s principal railway corridors, this infrastructure represents the challenge of reconciling the modernisation of the rail network with existing transport routes.

• Year of execution: 2009
• Location: Palanquinos, Spain
• Technical Solutions: Ground-supported falsework and Portal-frame falsework
• Full length: 623,00 m

Among the works carried out, the construction of an underpass using a pergola structural system stands out, considered one of the largest of its kind in Spain. Characterised by the use of concrete structural elements and a configuration adapted to the crossing of infrastructures, this solution highlights the complexity of its execution and the importance of precision at every stage of construction.
