25 De Abril Bridge (the Famous Red Bridge)

The 25 de Abril Bridge dominates the Tagus River’s skyline, its striking red steel arches linking Lisbon’s north bank with Almada to the south. Built in just 45 months and opened on 6 August 1966, the bridge was originally called Ponte Salazar; after the Carnation Revolution of 25 April 1974 it receives its present name, honoring the historic date. Designed by the American Bridge Company—the same firm behind the Golden Gate—the bridge is Europe’s longest suspension span, stretching 3,173 m with a main span of 1,013 m and a clearance of 70 m above the water.

Travelers experience the bridge in two ways. The upper deck carries six lanes of road traffic, while a lower deck added in 1999 supports the Linha do Sul railway, moving about 157 trains daily. For a closer look, the Pilar 7 Experience offers a guided tour and a viewing platform 80 m (262 ft) above the river, where you can admire the engineering details and panoramic views of Belém’s monuments. The bridge is toll‑free for pedestrians, though northbound vehicles pay €2.15. From its footpaths you can easily reach nearby attractions such as the National Coach Museum, the Monument to the Discoveries, Jerónimos Monastery and the Archaeology Museum, all within a few kilometres.
