„SZT. LÁSZLÓ” MOTORWAY - BRIDGE OVER THE DANUBE

Bridge structure: on both floodplains: steel box support bridge acting with rc plate, connected to the river bridge at both ends.
Innovative features of the bridge:
− The innovative structure of the rc deck slab and its dimensioning allowed to omit completely the moving of the supports, time- and work consuming activity.
− The longitudinal U ribs of the web plates and the soffit slab are not connected to the transverse girders spaced 4m from each other (suitability verified by finite element calculation and tests in 1:1)
− 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.
These yokes type REM 500 assembled with temporary supports produced in GDR were used also at the construction of other bridges.

The construction of Esztergom railway line began in the 19th century, originally the track has meant to be a commuter (local) line. 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.
