Abstract: A bridging device for a construction joint between a first construction part and a second construction part with several lamellae and at least one hydraulic control device for controlling the gap width between the lamellae. The hydraulic control device has double-acting hydraulic cylinders each with a movable piston and a piston rod arranged on the piston, each hydraulic cylinder being arranged on a lamella. Each piston rod is connected to a different lamella, wherein the piston defines a first working volume and a second working volume of the corresponding hydraulic cylinder. The invention is wherein the hydraulic control device comprises at least three double-acting hydraulic cylinders connected to each other by a hydraulic connection whereby the first working volume of each hydraulic cylinder is hydraulically connected to the second working volume of another hydraulic cylinder so as to form a hydraulic loop between the at least three hydraulic cylinders.
