Trepped Block Laminated Bridge in Biberach

Bridge Replacement Crossing Schoolyard


The bridge leads across a schoolyard. Therefore constraints in time and by the limited construction site have to be considered particularly in addition to a sustainable structure. The replacement structure is planned as a so-called block girder bridge constructed in timber. The structure bears on three steel supports that are bases on the distances of the former structure. The shortest span of 3.80m is designed as a cantilever, to avoid load application to the ancient town wall on the south side. Due to the large difference in height a slope of more than 6% results. Barrier-free accessibility cannot be guaranteed. The aim of this draft is to embed a contemporary wooden construction into vicinity. Particular attention is paid to a long-lasting constructional wood protection.

Length: 18,80 m
