Ponte 25 de Abril
Lisbon's first bridge across the Tagus River, linking the Alcântara and Almada districts, is a double-decker suspension bridge that stands 230 feet above the water and stretches more than 2 km (1½ miles). Reminiscent of San Francisco's Golden Gate Bridge, it's slightly shorter but still a spectacular sight from any direction. Cars and buses cross on the top tier while trains use the lower level, offering some great views. (The bridge is closed to cyclists and pedestrians.) Overlooking the bridge from a hill on the south bank is the Cristo Rei (Christ the King) statue, which is smaller than its famous counterpart in Rio de Janeiro but still an imposing sight. The interactive Pilar 7 Bridge Experience lets you access a panoramic viewing platform.
