Temporary bridge
A bridge that is only erected temporarily for a short period of time is called a temporary bridge (also known as an auxiliary bridge or emergency bridge ). So if the normal transition of a bridge z. B. not possible due to construction work is occasionally built temporary bridges to allow pedestrians and / or motor vehicles a transition. In individual cases, temporary bridges are or have been used permanently; one then speaks of permanent temporary bridges. So-called bridge devices can be used to erect temporary bridges, which are mostly prefabricated, easy-to-assemble steel framework superstructures. With regard to the substructures (e.g. pillars), simple constructions that cannot be reused are often used. As a makeshift bridge, however, it is also possible to set up another simple structure, often made from parts of broken bridges.
The first temporary bridges were produced by Gustave Eiffel .
