Pulvermuhl Bridge

Luxembourg
Luxembourg

Intended to supplement an existing railway viaduct, the structure was designed as a mix of concrete and metal that is organic in its nature. The piers that support the deck take their inspiration from the shape of a tree and are positioned in very sharp contrast to those of the arched viaduct (built in the early years of the 20th century) to which the new structure is to be attached. Each of the piers culminates in four branches that support the deck bearing two lines of track and a walkway for pedestrians. This form provided an elegant solution to the question of expansion joints. The cooperation with OVE ARUP Bridge Engineering made it possible to refine the forms and reduce the materials used to a minimum. The organic form integrates extremely well into the wild valley site, where respect for, and preservation of, the existing bio-diversity is a major focus of this project.
