Portugal: The 25th of April Bridge in Lisbon
Updated: Oct 27
The 25th of April Bridge is not just an engineering marvel but also a strong symbol for Portugal, linking the past and the present, the north and south banks. Naturally, it now plays a key role in the economy and development of the Lisbon region. Where and how to appreciate its impressive structure in photography.

History of the Bridge
The 25th of April Bridge was inaugurated on August 6, 1966, in Lisbon. Initially, it was named after António de Oliveira Salazar, the Portuguese dictator of the time. However, after the Carnation Revolution on April 25, 1974, which marked the end of the authoritarian regime, the bridge was renamed to commemorate this historic date.
Objectives and Achievements
The main goal of the bridge was to facilitate transit between the north bank of the Tagus, where the capital Lisbon is located, and the south bank, Almada. Before the construction of the bridge, travel was heavily restricted to ferries, creating bottlenecks and slowing down the economic development of the region. Its completion has thus served to invigorate trade, tourism, and exchanges between the two sides of the river.

Dimensions and Architecture
The 25th of April Bridge is often compared to the Golden Gate Bridge in San Francisco due to its similar red color and design. It was designed by the American company, American Bridge Company. The bridge spans 2,277 meters in length and has a height of 70 meters above the water to allow for the passage of ships.
The pylons peak at 190.47 meters. The bridge comprises two levels: the upper level for cars and the lower level added in 1999 for trains.

One of the unique characteristics of the 25th of April Bridge is its structural flexibility, allowing it to withstand earthquakes, a crucial element given the seismic activity of the Lisbon region. Additionally, it serves not only as a transit route but also as a symbol of freedom and change for the Portuguese people.
To admire the 25th of April Bridge in all its glory, several viewpoints are possible:
1. Belém: A historic district in Lisbon where you can see the bridge stretch across the Tagus River.
2. Cristo Rei: A giant statue of Christ located in Almada, offering a panoramic view of the bridge and the city of Lisbon.
3. LX Factory: A cultural and creative complex also offering a beautiful perspective on the bridge.

Fascinating Fog Phenomena
The climate in Lisbon is Mediterranean, characterized by hot, dry summers and mild, wet winters. Average temperatures range from 8°C in January to around 28°C in August. Humidity levels are generally higher during the autumn and winter months.
Fog or mist phenomena on the 25th of April Bridge are therefore more frequent during the autumn and winter months, generally between November and February. These phenomena are often due to temperature differences between the air and the water of the Tagus River, especially during cold mornings or evenings.
The presence of fog or mist is also influenced by other meteorological factors, such as wind direction and atmospheric pressure. Winds coming from the Atlantic Ocean bring increased humidity, thereby increasing the likelihood of fog.
During these conditions, the fog creates an almost mystical atmosphere, partially or fully enveloping the bridge. If you are fortunate enough to experience this during your stay, it's crucial to know from which locations to photograph it.

Interesting Observation Points in Case of Fog
The 25th of April Bridge, with its imposing dimensions and distinctive color, offers a captivating visual spectacle in all seasons. However, phenomena of mist and fog give it an almost ethereal dimension, making these moments particularly memorable for photographers fortunate enough to capture these magical instances.
When the bridge is enveloped in fog, some observation points offer particularly interesting views for black and white photography. Here are 4 that I have experimented with:
1. Miradouro da Senhora do Monte: This viewpoint offers a high vantage point of the bridge and is particularly striking when the fog is low and the bridge towers emerge through it.
2. Port of Belém: Here, you can see how the fog envelopes the base of the bridge, creating a dramatic effect with the visible parts of the bridge rising above.
3. Almada: The view from the south bank allows you to see the bridge emerging from the fog, with Lisbon in the background.
4. Parque Docas Ponte: This is where my photograph above was taken. It's a large, often empty parking lot. You can park easily and even observe the bridge from your vehicle if it's raining. The bank of the Tagus is just a few meters away. You will be alone and can thus take all the time you need for your long exposures.

The 25th of April Bridge serves not only as a physical link between two banks but also as a powerful metaphor for transition and transformation. In the climatic and atmospheric context, the fog that envelops the bridge can be seen as an allegory for the uncertainty and complexity of life.
Photographically speaking, these moments of mist offer an unparalleled opportunity to capture not only the architectural aspect of the bridge but also its emotional and symbolic essence. The interplay of shadow and light, exacerbated by the mist, adds a layer of visual complexity, transforming the bridge from a utilitarian subject into an object of art and contemplation.
