This bridge has a prestressed concrete deck, and the rest of the structure is ordinary reinforced concrete. It has three cantilevered spans. The central one is 58 m long, and the two lateral ones are each 51 m in length. The spanning structure includes several prestressed ribs, which were made at the workshop. As the ground was not sufficiently resistant, the foundations were built on piles, which have been placed both under the lateral and intermediate springers. The bridge has an overall width of 26 m. The pavement is separated into two independent carriageways by means of a central platform, which divides the traffic in opposite directions. The joints between the cantilevered sections of the arches, and the central girders, run diagonally to the plane of the deck. Thereby it is intended that differential settlements of the supporting bridge structure will not cause accidental cracking of the concrete.
