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)
Parisian canals
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.
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.
