19th century After extensive studies, a design by the Polonceau-Seguin group was selected, with as the engineer,
Marc Seguin and his brothers as architects, and Payen as the inspector. The ambitious project aimed to overcome the natural barrier of the valley with a grand viaduct. The foundation stone was laid on October 1, 1838, by the
Duke of Orléans. On September 9, 1840, the railway structure was inaugurated by
Louis Philippe I, King of the French—though he reportedly did not enjoy train travel. The viaduct was later named Hélène Bridge in honor of
Hélène de Mecklembourg-Schwerin, Duchess of Orléans and wife of the heir,
Ferdinand-Philippe d'Orléans. Despite local opposition in Meudon, construction was completed by September 1840, and commercial operations began on November 10, 1840. Special attention was paid to the viaduct's foundations, which xtend between underground to reach the
chalk layer, significantly increasing the project's cost. The arrival of the railway transformed
Meudon.
Bellevue, a residential area developed around 1824, expanded rapidly. The railway's route was partly designed to serve this emerging district, making it easier for Parisians—who already appreciated the village's charm—to visit on Sundays or settle there. Just a few hundred meters from the viaduct, the
Meudon rail disaster occurred on May 8, 1842.
21st century At the request of Meudon’s municipality, which sought to highlight its heritage, the ''Communauté d'agglomération Arc de Seine'' illuminated the Hélène Bridge to enhance its visibility and prominence. == Gallery ==
