Viaduct over the river Nela

The Santander-Mediterranean Sea line, designed to link the ports of Santander and Valencia, was in operation for more than fifty years from Cidad-Dosante in Burgos to Calatayud, where it connected with the Ferrocarril Central de Aragón (Aragon Central Railway). The project was conceived at the end of the 19th century, but materialised in 1920 when the State Government took over the preliminary studies. The line opened between 1927 and 1930, although the connection with Santander never took place, despite the construction of the La Engaña tunnel that crossed the Cantabrian mountain range. In addition, the line underwent shut downs and abandonment, and finally closed in 1985.

Along the route, more than a dozen tunnels and more than forty bridges were built, all of them of metal structure. This particular bridge, located at kilometre point 7 of the stage, was intended to allow the train to cross the Nela riverbed, an important tributary that rises in the mountains of Somo in the Merindad de Valdeporres and flows into the river Ebro near Trespaderne.

During the rehabilitation of the Santander-Mediterranean Sea railway line as a Nature Trail, the old metallic railway bridges, which were in different states of conservation, have been rehabilitated and commissioned. This bridge in particular is 63 m long. The restoration process aimed to ensure its use by pedestrians and cyclists.

Once the original structure was restored, auxiliary structures, new metal railings and a wooden deck were installed to adapt the bridge to its new use.
