Puente de la Constitucion de 1812 (Bridge of the 1812 Constitution), Cadiz

The Puente de la Constitucion de 1812 (Bridge of the 1812 Constitution) is a cable- stayed bridge that crosses the Bay of Cádiz, giving access to Cádiz from the mainland, being the third access to the city, after the link by the isthmus of San Fernando and the Carranza bridge. The bridge is the continuation of the South highway, forming an integral part of the Cádiz access highway , the Ministry of Public Works being responsible for it. The board is distributed between the dual carriageway (two lanes in each direction) and another carriageway reserved for public transport.

Construction of the bridge began in 2008 and was opened on September 24, 2015 . 6 Once inaugurated, it became the bridge with the longest span in Spain with 540 meters. Considering the cable-stayed bridges, it would be the third longest in Europe, after the Normandy bridge (856 m) and the Rio-Antirio bridge (three 560 m spans). The total work consists of the bridge over the bay, with a total length of 3,092m, 1,440 of which are over water, plus the 796m Río San Pedro Viaduct. With the accesses to the bridges, the work extends over 5 km.
