Bridge and Normandy Bridge. The maximum height above the sea level is 69 meters, with two pylons of 187 meters, making it one of the tallest bridges in Europe. They are 30 meters higher than the pylons between both sides of the bay. The bridge connects the San Pedro River (district) in Puerto Real with the |neighborhood of La Paz in Cadiz. The construction project The proposed construction of a new access to the city of Cadiz by way of a bridge over the Bay has its origins in the Order of Highways Studies in April 2003, which in turn took into account various studies dating back to 1989. The aim of the project was to resolve the traffic congestion problems suffered by the access to Cadiz from Puerto Real (Bridge José León de Carranza and CA-33). The draft included studies for three riders that link the N-443 in the San Pedro Bay crossing access into Cádiz: A. Northern Zone Cabezuela straight through Bay area reaching the shipyard in Cadiz, past the northern edge of spring Cabezuela. B. The limit shipyards factory in Matagorda, and after passing through the southern end of spring Cabezuela, describes an arc in the bay to reach the area also shipyards in Cádiz, thus saving the channel navigation, in order to reduce the junction depth. C. Continued on the trace of the N-443, and when one reaches the edge of the bay, on the southern edge of Astilleros de Matagorda, crosses S for describing a road connecting with the city in the Props area, connecting with the new diagonal Avenue and Bay. In all three cases a cross section separated by two lanes, shoulders and median lanes are envisioned. Regarding the crossing structure bay, the three paths are designed in submerged tunnel. Moreover, in the "A" alternative solution fixed bridge large gauge was studied because it was the only one whose configuration permitted naturally, across a single alignment channel surfing and having a path straight admitting great light openings for the passage of ships. Similarly, three alternatives were studied bridge: archery, cable-stayed and suspension. The "A" alternative structure bridge for crossing the Bay was selected as the best solution for urban traffic on both banks of the bay, the lowest investment also considered that nicely integrates both urban planning and landscape. Of the different types of bridge studied, the braced was selected as the lowest
