Kiskörei Tisza BridgeOverview
Originally the Kiskörei Tisza Bridge was built as railway bridge in 1940, but in 1958 due to upgrade works it became a mixed use crossing which is used by the railway as well as road vehicles.
On the bridge, the railway tracks were sunk into the concrete surface of the single traffic lane. The traffic is regulated by traffic lights at both ends of the structure allowing only trains or road vehicles to cross the bridge from one direction at a time.
Since the bridge structure is nearly 50 years old the Hungarian Road Authorities decided the renovate the whole structure. The expansion joints were replaced in 2018.
For this project, mageba supplied three units of TENSA-FINGER joints of type F80 with movement capacities of 20 mm and 40 mm, and one unit of type F160 with a movement capacity of up to 80 mm.
The joints were chosen partially due to their excellent fatigue resistance and suitability for heavy traffic load.
The F80 joints were installed at pillar I, III and IV, whereas the F160 was built in at pillar II of the structure. The joints were installed in sections due to the railway tracks that were also replaced during the renovation works.
