Temporary bridges
It is essential to minimize disturbances when carrying out maintenance and repair work on railway networks.

Culverts, roads, paths or even entire bridges can be constructed under these temporary bridges. LEONHARD WEISS can supply everything you need from one single source when installing and disassembling temporary bridges.
