The Montabliz viaduct became the tallest ever constructed in Spain.
The Montabliz viaduct, situated on the stretch of the A67 highway and built by Ferrovial Construction, signified a real milestone for the construction company. The infrastructure that connects Cantabria with the nearby plateau crosses a geological fault and rests on 4 piers measuring up to 130 meters.
With a length of 721 meters, the Montabliz viaduct protects the riverbed of the Bisueña River. It also passes at the highest point of the valley floor. The viaduct plan has a 700 meter radius and its longitudinal profile is shown on a slope.
