Railway bridge WK432, Bytom

Übersicht

Project description

This bridge was constructed in 2010-2011 near the city of Bytom in southern Poland, to carry a railway line over the A1 motorway. The new construction of the motorway in this area necessitated the building of a bridge to enable road and rail traffic to flow freely at the crossing point.

The bridge consists of two reinforced concrete structures, side by side – one for each of the two railway tracks. Noise reduction measures were necessitated by the presence of a residential area close to the bridge.

mageba scope

mageba supplied TENSA-MODULAR expansion joints for the construction of this bridge. Four joints were required, one for each end of each structure. The joints are of type LR8-RW, the suffix “RW” standing for “railway”. They are designed for the particular challenges presented by railway bridges, such as the ballast stones that would block the gaps of a normal modular joint and must be prevented from entering the gaps, and the high axle loads and vibrations from rail traffic.
The joints also feature ROBO-MUTE noise-reducing mats underneath, to reduce noise under traffic.
