One of the symbols of Luxemburg city and a favorite tourist attraction is the Adolphe bridge over the river Pétrusse. At the time of construction, it was an exciting architectural endeavor to build a stone arch bridge with a main parallel arches span of almost 85 meters. Initially, the bridge carried tram rails and lanes for road traffic. Nowadays, the bridge has two decks, upper for cars, trams, and pedestrians, and lower for bicycles. Named after Grand Duke Adolphe, who abolished the personal union after the death of King William III of the Netherlands, and sovereignly ruled Luxembourg. For the citizens of Luxembourg, this bridge is a symbol of independence.
