A1 Motorway Bridges, Maciejów

Project description

Autostrada A1, the Polish part of European route E75, stretches the length of Poland from the northern Baltic coast to the Czech border in the south with a length of 568 km. The motorway was newly constructed or re-constructed along its entire length in recent years, and mageba played a part in the construction of many of its bridges.

The section between the towns of Piekary Śląskie in southern Poland and Maciejów in central Poland contains many bridges, a number of which were constructed using mageba products.

mageba scope

mageba supplied a large number of TENSA-MODULAR expansion joints for the construction of the bridges on this section of motorway. These included 24 large joints with nine movement gaps or more, among others: twelve joints of type LR12 (with 12 gaps per joint), two joints of type LR11, six of type LR10-RW and four of type LR9. The six joints of type LR10-RW are railway bridge expansion joints (as indicated by the suffix “RW”). These are designed for the particular demands of railway bridges, where ballast stones would block the gaps of a normal modular joint, and loading is very high.
