Approach to the conceptual and structural design of the viaduct over River Almonte

Abstract

The Viaduct over River Almonte, with its 384 m arch for the new high-speed rail, has been a real technical challenge from the point of view of design and construction. From the very beginning, Juan José Arenas has in mind that, given the conditions of layout, orography and foundation on rock, the right solution is a concrete arch bridge. Because the arch resisting by form, is the most efficient, safe and rigid way to make this structure, but also because of an unavoidable commitment to durability.
