Caulaincourt Bridge, Road bridge in 18th arrondissement of Paris, France

Caulaincourt Bridge is a 160-metre riveted-steel road bridge carrying rue Caulaincourt over Montmartre Cemetery in the 18th arrondissement. It has two traffic lanes and two pavements, and rests on six cast-iron Doric columns founded inside the cemetery, above divisions 17 and 18 near the Carrefour de la Croix.

The bridge was completed in 1888 after facing initial opposition from local communities and authorities. Its construction reflected late 19th-century efforts to improve transportation connections in the expanding city of Paris.

The street is named after Armand de Caulaincourt, Napoleon's general and foreign minister. The bridge appears in François Truffaut's 1959 film The 400 Blows; Truffaut, who grew up around Place de Clichy, is buried in the Montmartre Cemetery beneath it. It also features in Diane Kurys's 1977 film Peppermint Soda and plays a large role in the novel Le Mariage de Fantômas by Pierre Souvestre and Marcel Allain.

The bridge sits in a well-connected area with several bus lines and metro stations nearby serving different neighborhoods. Pedestrian access is straightforward, and the structure can be easily crossed while experiencing the unusual perspective it offers.

During foundation work in 1887, workers found a complete mammoth skeleton; only the teeth were kept. The bridge was also the first in Paris built with riveted steel beams, and it appears in François Truffaut's 1959 film The 400 Blows.
