José Leon de Carranza Bridge, Highway bridge in Cádiz Bay, Spain.

The José Leon de Carranza Bridge is a highway bridge that crosses the inner bay of Cádiz. The structure is supported by twenty-seven concrete pillars embedded in the seabed to keep the road suspended above the water.

Eduardo Torroja designed the first bridge project in 1927–1928, but opposition from San Fernando councils and economic doubts blocked it. Mayor José León de Carranza revived the idea after 1948, and the bridge finally opened in 1971, becoming the first road link between Cádiz and the mainland.

The bridge carries the name of José León de Carranza, mayor of Cádiz from 1948, who revived his father Ramón de Carranza's earlier push for a fixed link to Puerto Real. Its 90-metre movable span, one of the largest in Europe, opens for ships heading to the La Carraca arsenal and the San Fernando shipyards.

Both cars and pedestrians can use the bridge, which provides a straight route between the two cities. Visitors should be aware that the central section can be raised for large ships, occasionally causing closures.

A central section of the structure can be raised to allow military vessels to reach the La Carraca shipyard. This movable feature is uncommon for a bridge of this length.
