Passerelle, Stone viaduct in Luxembourg City, Luxembourg
The Passerelle is a stone viaduct across the Petrusse Valley in Luxembourg City measuring 290 meters long and 45 meters high. Twenty-four stone arches support the 17.64-meter-wide roadway, which carries both vehicles and pedestrians.
A British firm called Waring Brothers built this viaduct between 1859 and 1861 to connect the city with a new railway station located outside the fortress walls. The project allowed the city to expand across what had been an isolating valley.
The structure connects two parts of the city that people use every day to move between neighborhoods. It has become a familiar part of how residents navigate their way around the city.
You can cross the Passerelle on foot or by car while enjoying the deep view into the valley below. The best view of the structure is from below in the valley or from one of the surrounding riverbanks.
Engineers incorporated a slight curve into the design to meet military requirements for defending the fortress. This hidden technical solution shows how closely the structure and city defense were linked.
