The 25 de Abril Bridge is a suspension bridge connecting the city of Lisbon to the municipality of Almada on the south bank of the Tagus river. To the inaugurated bridge in 1966 a train platform was added in 1999. Because it is a suspension bridge and has similar coloring, it is often compared to the Golden Gate Bridge in San Francisco, US. With a total length of 2,277 m, it is the 32nd largest suspension bridge in the world. The upper deck carries six car lanes, while the lower deck carries two train tracks. Until 1974, the bridge was named Salazar Bridge. The name "25 de Abril" commemorates the Carnation Revolution.
