This coin visited the A1 highway bridge Leverkusen in the north of Cologne, see the attached pictures.
Build in 1965 for about 50,000 cars per day, it has to manage 120,000 cars and lorries per day today on three lanes per direction. During a revision, damages have been found, and a closer inspection yielded that low quality steel has been used in the 1960s instead of the scheduled high quality steel.
Now three lanes have been reduced to two, the speed limit was set from 100 km/h to 60 km/h, and the bridge is closed for everything heavier than 3.5 tons. Police controls caught 20,000 (in words: twenty thousand) lorry drivers, that simply ignored the closing, alone in the last month.
Engineers say they are happy if they could keep the bridge open until a new one will be (hopefully) ready in 2020.
