The bridge had heavy traffic from the beginning; it was for a long time the widest bridge in Paris. It has undergone much repair and renovation work, including rebuilding of seven spans in the long arm and lowering of the roadway by changing the arches from an almost semi-circular to elliptical form (1848–1855), lowering of sidewalks and faces of the piers, spandrels, cornices and replacing crumbled corbels as closely to the originals as possible. In 1885, one of the piers of the short arm was undermined, removing the two adjacent arches, requiring them to be rebuilt and all the foundations strengthened.
