Bridge for enabling small animal e.g. otter, to cross river, has individual components with running surface and two side parts, where components are connected with one another by hooks and made of concrete material

摘要

The bridge has individual components with a running surface (13) and two side parts (15), where the components are formed as straight and bent and/or angled parts. The angled parts are end and intermediate parts for integration in the embankment of the river. The components are connected with one another by interleaved hooks or by the using connecting parts (19). The components are made of concrete material i.e. concrete, exposed aggregate concrete, porous concrete or reinforced concrete. Geological substances such as sand and gravel are provided on the running surface in variable mixture.
