The Lisbon bridge celebrates 50 years
One of the most iconic symbols of Lisbon, the 25th April bridge, is an impressive construction that celebrates half a century in 2016.
Lets recap a bit of history about this bridge..
2016: the Tagus river bridge remains a symbol of the Portuguese capital
Since 1876 the ideia of a bridge linking both banks of the tagus river in Lisbon was in place, however only in the 1950`s it was decided to begin its construction.
At the time the bridge cost was the equivalent to 11 million euros, with some of the money being agreed with USA Banks.
For engineers this bridge was a major challenge since back then there were few suspended bridges in the world of this size and therefore not many expertise available. The design of the bridge, contrary to popular belief, was not influenced by the San Francisco Golden Gate but from the Bay bridge in the same city in Califórnia.
Construction works in the 1960´s
Despite more than 3000 workers being involved on its construction,only 60 casualties were confirmed which is quite a low number considering the lack of modern safety procedures in the 1960`s.

The main reason for this bridge existence was to develop the tagus river south bank, an area highly undeveloped compared to Lisbon in the opposite side of the river.

In terms of politics this construction was meant to show the dictatorial regime strength and power since it was already suffering from a strong popular opposition. This popular disbelief was mainly due to the underdevelopment of the country compared to western Europe standards as well as the lack of freedom civil rights.
