| Abstract: |
The bridge over the Cádiz Bay has a total length of 3157 m and crosses from Cádiz City to Puertorreal. The main bridge is a cable stayed solution with a main span of 540 m and approach spans of 200 m. and a maximum vertical clearance of 70 m. It will be one of the longest cable- stayed bridge in Europe. The deck is a trapezoidal box girder 3.0 m deep in a composite construction steel concrete in the bridge over the bay and prestressed concrete in the bridge on the land side. The simply supported deck has a variable depth made of steel with an orthotropic deck. The total width varies from 33.20 to 34.20 m. The bridge will support 2 lanes carriageways for vehicles and 2 tracks carriageway for a tram. The pylon is a double Y shape reinforced concrete structure. The bridge is currently under construction. The main span will be built by free cantilever system with 20 m long segments. The approach span on the Cadiz side will be built by incrementally launched segments. The approach spans on the Puertorreal side will be constructed span by span with a centering. The simply supported 150 m span will be lifted from a barge. |
