The project for doubling The Pulvermühle viaduct was awarded in the “Steel Construction 2020 Bridges” competition organized by Infosteel.
The project stood out among 26 projects and received the 1st prize in the category “Grand Duchy of Luxembourg”.
The Pulvermühle viaduct, which crosses the Alzette valley in Luxembourg City, was inaugurated in June 2019 after 10 years of work. The worksite was complex because it was necessary to find the right solution to go from 2 to 4 lanes without altering the character of the site.
The bureau greisch carried out various missions in this project: study of the launching of the steel structure, calculations of deformation of the work, study by finite elements of the nodes, study of the access ramp in polystyrene and study of concreting by blocks of the slab.
