The mandate was for the construction of a staircase to link the deck of the Jacques Cartier Bridge to Saint-Charles Street in Longueuil. The staircase is a sculptural object, both opaque and transparent, which marks its presence day and night. The staircase is made entirely of galvanized steel in which a linear and functional LED lighting is integrated. The steps, landings and railings are made of grating constructed from galvanized steel sections. Steel plates are integrated to allow for the circulation of bicycles. Taking advantage of the views that open onto the Jacques Cartier Bridge, and in order to make the descent and ascent segmented with breaks, the structure is punctuated with lookouts. The staircase becomes more than a utilitarian piece of equipment and allows several users to cross each other while offering spectacular stops and views of the river, the City of Montreal and the City of Longueuil.
