The 25th of April Bridge is a suspension bridge in Lisbon, Portugal, very similar to San Francisco's Golden Gate Bridge. It crosses the Tagus River, connecting the capital to the city of Almada. Inaugurated in 1966 as the Salazar Bridge, it was renamed after the Carnation Revolution on April 25, 1974, in commemoration of the end of the dictatorship. It is a vital structure that carries both vehicles and trains.
