Karlssteg

The Karlssteg is a 136.5 meter long footbridge of tension construction in Freiburg im Breisgau, Germany.

A concrete strip only 25 cm thick with 60 continuous tension elements leads from Karlsplatz to the Stadtgarten.

At the opening, a four-tonne construction vehicle stood alongside Lord Mayor Eugen Keidel [de] on top of the 664.000 Deutsche Marks (approximately 300,000 British pounds) to demonstrate the load-bearing capacity.

The artificial resin coating on the bridge causes problems due to its loosening from the concrete, and has had to be renovated several times over the last few years.

Therefore, in the event of snow and ice, barriers with warning signs are put in place to prevent pedestrians from crossing the bridge.
