Paris Metro Line 6 on Pont de Bir-Hakeim toward Passy

Paris Metro Line 6 traverses the Seine River on the Pont de Bir-Hakeim, a distinctive two-tiered bridge completed in 1905. The upper level carries the elevated metro line, a design choice made to ensure ventilation for the early steam-powered trains and to offer unobstructed city views. The bridge's steel viaduct construction, characterized by riveted beams, reflects the engineering practices of the early 20th century. In the distance, the architecture of the Passy district in the 16th arrondissement is visible, showcasing Haussmannian style buildings.
