The Grand-Pont was originally 180 metres long, reaching 25 metres at its greatest height and using two levels of 5 and 19 arches, respectively. Filling the Flon Valley made the lower level disappear in 1874. This monumental work radically changed the southwest view of the city, drawing out its outer limits. It became the symbol of the modern city and the industrial revolution that was beginning.
