The video below (in German) shows how the installation of such a gantry system works. The footage shows the installation of a 34 meter wide aluminum traffic sign bridge on the A81 highway near Singen in southern Germany, as well as other interesting details about the use of the material aluminum and its advantages. The planning of an operation to install a gantry is very complex, as a full closure of the highway is necessary for the installation. However, SWARCO manages to keep the closure at only 5-10 minutes.
