Concepción general del proyecto del Puente de la Constitución de 1812 sobre la Bahía de Cádiz

Different construction techniques have been employed, and have been adapted to the different bridge typologies, and to its location in the sea or on land. The cable stayed main bridge is being built using a free cantilever system with segments 20 m long. The approach viaduct over the sea is being built by segments incrementally launched from Cadiz side. The approach viaduct on Puerto Real side is being built by span by span by means of a shoring framework. The simply supported 150 m main span will be lifted from both piers with a barge.
