MOTORWAY - BRIDGE OVER THE EASTERN MAIN CHANNEL

Bridge structure:
Two parallel girder bridges with wedged steel supports acting with the rc plate.
Innovative characteristics of the bridge:
− The innovative structure of the rc deck slab and the method of its dimensioning allowed to omit completely the relocation/moving of the supports, time- and work consuming activities.
− For the in-site assembling procedure of the steel structure temporary supports were used, replaceable by crane in 1 piece and not needing separate foundation work (REM 500 type temporary supports produced in GDR)
These yokes type were used also at the construction of other bridges.
− The steel pipe yokes used also for the concreting of the deck slab were constructed on the temporary backfills along the two riversides.

The primary goal of the railway track was to secure the supplement of coal for Budapest’s factories and population. In the 20th century the coal mining dropped back and the surrounding settlements rapidly increased. The role of freight traffic was taken over by the suburban passenger traffic.
