Altenbergsteg, Chain footbridge in Altenberg, Switzerland

Altenbergsteg is a 54-metre-long, 2-metre-wide steel-chain suspension footbridge over the Aare in Bern, linking the old town with the Altenberg quarter. It has a narrow walkway and stands a few metres below and to the side of the much higher Kornhausbrücke, opened in 1898.

A wooden bridge with a toll house stood on this site from 1834; before that, a ferry introduced in 1823 carried people across the Aare. The present steel-chain suspension bridge was built in 1857, making it the oldest surviving steel-chain suspension bridge in Switzerland. In 1898 the much higher Kornhausbrücke opened a few metres to the side, above the Altenbergsteg.

The bridge is part of the "Allez Hop-Träff" running course, yet jogging on it is expressly forbidden. Aare swimmers use it, upstream of the Lorraine open-air pool, to jump into the river. It is listed as Swiss cultural property of national significance, KGS no. 666.

The crossing is reserved for pedestrians: motorbikes and bicycles are not allowed, and jogging is prohibited even though the bridge is part of the "Allez Hop-Träff" running route. Bathers use it to jump into the Aare upstream of the Freibad Lorraine. It lies a few metres below and beside the much higher Kornhausbrücke of 1898.
