The 25th of April Bridge is one of those landmarks I encounter constantly while working around Lisbon — whether pointing it out to visitors, crossing the river, or fielding questions about its history and design. Over time I’ve become familiar with the stories behind it through everyday exposure, curiosity, and research sparked by those conversations. This guide pulls together that perspective to highlight some of the details that make the bridge more interesting than it first appears.
The 25th of April Bridge
The 25th of April Bridge in Lisbon (Ponte 25 de Abril) is more than just a beautiful structure stretching across the Tagus River—it’s a living symbol of Portugal’s modern identity. With its striking reddish steel profile, monumental engineering, and deep historical meaning, this suspension bridge remains one of the top Lisbon landmarks, crossed daily by commuters, adventurers, and curious travelers alike.
Whether you’re exploring the Lisbon waterfront in Belém, taking a ferry from Cacilhas, snapping sunset photos from Cristo Rei, or sailing beneath its steel underbelly, the bridge has a presence you can’t ignore.
Today we’re going to dive deeper—past the postcard beauty—into 12 fascinating facts about the 25th of April Bridge that will give you more insight and more appreciation, along with insider tips on the best experiences, views, and ways to see it up close.
12 Fascinating Facts About the 25th of April Bridge in Lisbon
1. A Bridge with Two Names: From Ponte Salazar to Ponte 25 de Abril
When the bridge was inaugurated on August 6, 1966, it was named Ponte Salazar after Portugal’s dictator, António de Oliveira Salazar. After the peaceful Carnation Revolution on April 25, 1974, the bridge was renamed Ponte 25 de Abril, honoring the day democracy was born in Portugal.
Crossing the bridge today is like traveling over a chapter of living national history.
2. Lisbon’s Golden Gate Twin
If you think the 25th of April Bridge looks like the Golden Gate Bridge in San Francisco, you’re not imagining it. Both bridges:
Were built using American Bridge Company expertise
Share a suspension bridge design
Feature massive steel truss supports
However, Lisbon’s version stands proud in a darker reddish-brown tone that beautifully complements the Lisbon skyline.
3. Among the Longest Bridges in Europe
The Ponte 25 de Abril measures:
2,277 meters in total length
1,013 meters in central span
70 meters above water level
That makes it one of the longest suspension bridges in Europe, and a massive engineering achievement for the 1960s—a time before computer-assisted construction.
4. Two Levels of Traffic Powering Lisbon
Originally, the bridge carried only road traffic. But in 1999, a second lower deck was added, transforming it into a dual-level masterpiece:
Upper level – Road
Lower level – Train connections to Setúbal, Faro, and the south
If you’re staying on the other side of the river, crossing the bridge gives unforgettable skyline views.
5. Built for Earthquakes
Lisbon has a long—and tragic—relationship with earthquakes, most famously the catastrophic 1755 quake. Engineers designed the 25th of April Bridge to withstand significant seismic activity. Its reinforced structure and flexible design can absorb extreme vibration and stress.
It’s beautiful and built for survival—just like Lisbon itself.
6. A Record-Breaker Built Under Budget
This megaproject required:
Over 82,000 tons of steel
2,300 workers
Just 45 months of construction
Even better? It was completed ahead of schedule and under budget—something that seems almost unimaginable for a modern mega-bridge.
7. One of Lisbon’s Best Photography Subjects
Whether you shoot with a DSLR or a mobile phone, this bridge delivers:
Blue hour silhouettes
Fiery sunsets
Majestic views with Cristo Rei behind it
Golden reflections over the Tagus
Best angles?

8. A Lifeline for 150,000 Vehicles a Day
More than 150,000 vehicles cross the bridge daily, making it one of the busiest routes in Portugal. Northbound traffic pays tolls that go directly toward maintenance—ensuring the bridge stays structurally sound despite its colossal daily demand.
Whether you’re heading south for:
Beaches of Costa da Caparica
Seafood restaurants in Sesimbra
Wine tasting in Setúbal
…the bridge is your gateway.

A multimedia exhibition
History of construction
A dizzyingly good lookout point 80 meters up
