The Pont au Double () is a bridge over the Seine in Paris, France.
The bridge links the 4th and 5th arrondissements of Paris, from the ÃÂle de la Cité to the quai de Montebello.
In 1515, Francis I was asked to build a bridge over the small branch of the Seine in order to carry patients to the Hôtel-Dieu hospital on the ÃÂle de la Cité. Construction began in 1626 and in 1634 the two sides were connected.
In 1709, the bridge collapsed. It was rebuilt and remained in place until 1847. In 1883, the Pont au Double was replaced by a one arch cast-iron bridge.
