• Bridging devices as used in particular on road bridges, in order to compensate for the changes in the length of the superstructure caused by thermal expansions, are known and used in different embodiments. Differences are in particular bridging devices with La ⁇ , which are arranged within the joint gap between and parallel to the joint edges and are supported on the expansion joint bridging trusses, on the one hand and slat-free bridging devices on the other. Bridging devices with slats are particularly suitable for bridging expansion joints with a comparatively large working range (difference between maximum and minimum joint width). However, they are relatively expensive to manufacture, require a large installation space, and also the installation is complicated and time consuming.
