Alconétar Bridge over the River Tagus at Alcántara Reservoir, Cáceres, Spain

This article describes the main characteristics and the special building system used for the Alconétar Bridge that crosses A-66 motorway over the Alcántara Reservoir, in Spain.

The bridge, whose main stretch is formed by a metal deck arch with a span of 220 m, was carried out by using a series of techniques: deck launching, tilting and lowering large pieces, swivel lifting and rotating quarter arch sections, lowering the semi-arches and then crown closure.
