Abstract

The temporary bridges over the Ahr A devastating flood in the Ahr valley in July 2021 claimed 134 lives and caused massive damage to the infrastructure, including bridges. The flood wave was caused by a combination of factors, including heavy rainfall, a large catchment area, saturated soils, narrow valleys, and slate slopes. The numerous bridge structures partially acted as a temporary dam, which eventually failed and was washed away under the pressure of water and debris, causing the already flood‐like flow of the Ahr river to accumulate into a flood wave. Around 60 bridges were destroyed, and in the town of Bad Neuenahr‐Ahrweiler alone, 23 out of 25 bridges were destroyed. In order to quickly provide helpful solutions for the affected citizens, some temporary bridges had to be erected to bridge the planning and construction time for new permanent structures. This article reports on these temporary bridges and their construction. [ABSTRACT FROM AUTHOR]
