Paris has 37 bridges across the Seine, of which 5 are pedestrian only and 2 are rail bridges. Three link Île Saint-Louis to the rest of Paris, 8 do the same for Île de la Cité and one links the 2 islands to each other. A list follows, from upstream to downstream:
Pont de Bir-Hakeim (crossing the Île aux Cygnes, comprising one stage with a railway bridge carrying Line 6 of the Paris Métro and another for road traffic)
Pont aval (used by the boulevard périphérique, at the river's exit from the city)
The Parisian canals[fr] are crossed by a number of bridges – the majority of which are passerelles piétonnes (footbridges) – and many of the road bridges can be raised or turned (temporarily interrupting road traffic) to allow canal traffic through.
There are several other bridges in Paris which do not cross a body of water. In the 10th arrondissement, Rue La Fayette and Rue de l'Aqueduc pass over the train lines of gare de l'Est. On the boundary between the 5th and 13th arrondissements, boulevard de Port-Royal spans Rue Broca and Rue Pascal. In the 18th arrondissement, rue Caulaincourt is carried over the Montmartre Cemetery by a bridge. In the 20th arrondissement, rue Charles-Renouvier spans rue des Pyrénées. In the 8th arrondissement, rue du Rocher crosses rue de Madrid.
Also, lines 2 and 6 of the Paris metro include several aerial viaducts in their above-ground zones, whilst RER C also has a viaduct along the length of quai André-Citroën.
Footbridges may also be found in the Parc des Buttes Chaumont and parc de Reuilly. Among others, the promenade plantée uses the old viaduc Daumesnil. In bois de Vincennes, the islands of Bercy and of Reuilly are linked to each other, and the east of the latter to the rest of the park.
