A three-arched bridge, the Pont de Grammont, connecting it to Quai St-Bernard across the backwater called the bras de Grammont, was under construction in 1836, according to Galignani's New Paris Guide, but in 1847 the narrow space separating it from the Right Bank was filled in and joined to Quai Morland. During the Revolution of 1848 the new ground was temporarily used for an encampment of the army.
