Montabliz viaduct, situated on the stretch of the A67 highway and built by Ferrovial Agroman, 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. This viaduct became the highest ever constructed in Spain.
