Eiserner Steg PhotoStory

Deir Eiserner Steg this an iron footbridge. It is located in Frackfurt, Germany. The first bridge in Frankfurt was the Altebrucke. The people from that period needed another bridge because the bridge which was established decades before had a lot of traffic. Around the year 1868, the people was allowed to build this bridge.

Actually it’s a suspension bridge. Deir Eiserner Steg has a way stronger structure. The bridge was a total success among the cities of Frankfort. It was designed by Johann Peter Wilhelm Schmick, and it crosses a 174 meters distance. The citizens were so pleased with Schmick work that they started to say “No Bridge Without Schmick”. In 1911-1912 the bridge was rebuilt after a ship accident.
