Odins Bridge

Odin's Bridge consists of a stretch of road with a fauna passage and a meadow bridge over the sensitive Bispeengen natural area west of the Odense Canal, a movable bridge over the Odense Canal, and a meadow bridge east of the Odense Canal. The starting point has been a facility that provides the fewest interventions in the existing nature. Odins Bro is a double swing bridge, where the two pivots are located inland, both west and east of the canal. The bridge is thus designed so that no navigational obstacles are placed in the way of ship traffic to the Port of Odense.

On the west side, approx. 600 m connection section and dam for connection with the main road. On the eastern side, a corresponding connecting section and a short embankment connecting the bypass to the further road course. The connecting courses cross over a low, environmentally protected meadow area. That part of the bridge connection is made of prestressed concrete. Similarly, for the connecting bays on the eastern side of the canal. The canal crossing is designed as a double swing bridge with a total span of 200 m and lateral spans of 37 m.

Among the largest swing bridges in Europe

The swing bridge is one of the largest in Europe and, as far as is known, the only one that swings according to the bearing principles used here. The spans have been determined based on a desire to protect the environment around the canal banks and carry the roads and cycle paths along the canal as before. Therefore, the supports on which the rotation of the bridge parts takes place are located so far inside the bank that the bridge in the open position does not protrude beyond the channel widths. This ensures that there must be no fenders in the channel itself.

The main structure is designed as a twin box girder bridge in steel with a 3 m opening between the boxes. The bridge deck structures are braced by a single-level triangular steel structure with a maximum height above the bridge deck of 20 m. The main supports for the swing spans carry both the permanent bearings for the bridge and the bearing system used for rotation. The concrete cylinder's diameter that forms the bridge section's foundation is reinforced concrete. The hydraulic system that activates and controls the bridge movement is located inside these concrete cylinders. The dehumidification system and electrical control system are similarly located here.

What calls for particular interest in movable bridges is, of course, the bearing systems and the actuation systems for movement of the bridge. A completely new system has been developed for the swing bridge bearing and the connection to the end abutment on the current bridge. Furthermore, the bridge design is unique due to the arrangement with 3 m of free space between the bridge boxes, which has been desired for the sake of penetrating light - this applies to the bridge's entire length, including the connection bays. The monoplane load-bearing structure gives the bridge a much calmer appearance from many angles.
