Opening of the bridge over the Tagus
The 25 de Abril Bridge (Ponte 25 de Abril, 25th of April Bridge, Portuguese pronunciation: [ˈpõt(ɨ) ˈvĩt i ˈsĩku ðɨ ɐˈβɾiɫ]) is a suspension bridge connecting the city of Lisbon, capital of Portugal, to the municipality of Almada on the left (south) bank of the Tagus river. It was inaugurated on August 6, 1966, and a train platform was added in 1999. It is often compared to the Golden Gate Bridge in San Francisco, US, because they are both suspension bridges of similar color. It was built by the American Bridge Company which constructed the San Francisco–Oakland Bay Bridge, but not the Golden Gate. With a total length of 2,277 metres (7,470 ft), it is the 32nd largest suspension bridge in the world. The upper deck carries six car lanes, while the lower deck carries a double track railway electrified at 25 kV AC. Until 1974, the bridge was named Salazar Bridge. The name "25 de Abril" commemorates the Carnation Revolution.
