Montabliz Viaduct

Abstract

The design, project and construction of the Montabliz Viaduct allow the Meseta Dual Carriageway to pass over the river Bisueña valley in the province of Cantabria. Its 145 m height, with the highest pier in Spain - amongst the four largest built to date in Europe -, its 175 m central span -built using the cantilever technique - and the design of its cross section -solved by means of a single box for the two carriageways, with a 26.1 m wide roadway - make the solution designed a very unique structure, constituting a basic connection element and public work playing a worthy role matching its surrounding.
