The Pont des Invalides is the lowest bridge located in Paris (France) and crossing the Seine between the 7th and 8th arrondissements. It is one of 37 bridges across the Seine.
This site is served by the Champs-Élysées – Clemenceau, Alma – Marceau, Invalides and La Tour-Maubourg metro stations.
It bears this name because of its proximity to the Esplanade des Invalides.
The story of this bridge started in 1821, when engineer Claude Navier conceived a technologically revolutionary bridge that crossed the Seine in one single reach without any point of support in between. The proposed suspension bridge, the construction of which started in 1824, was meant to be erected opposite to the Hotel des Invalides on the site of the current Pont Alexandre III.
In response to complaints from the defenders of the Invalides perspective, the Public Services decided to shift the bridge site downriver. Therefore, in 1829, two engineers, de Verges and Bayard de la Vingtrie, completed the construction of a proper suspension bridge supported by two piers in the Seine and three porticos, each 20 m in height. Unfortunately, due to rapidly growing wear on the bridge, its access had to be regulated in 1850.
In 1854, the bridge was demolished to be replaced by a new one in time for the upcoming Exposition Universelle (1855) in Paris. Paul-Martin Gallocher de Lagalisserie and Jules Savarin used the existing piers of the former suspension bridge and a newly added central pier to build an arch bridge in masonry on the same site. The new pier was adorned with sculptures in two allegorical themes: the Land Victory by Victor Vilain upriver; the Maritime Victory by Georges Diébolt downstream, whereas the two old piers were adorned with sculptures of military trophies bearing the imperial coat of arms, both the work of Astyanax-Scévola Bosio.
Despite being stronger, the new bridge still sustained a subsidence between 25 and 30 cm in 1878, and lost two arches during the winter of 1880 (restored by the end of the year). The bridge has been quite secure since then and the only modification made in the 20th century was the expansion of its pavement in 1956.
