As Tiefenaubrücke are two immediately next to each other bridges - a road and a railway bridge - through the Aar downstream of Bern , respectively.

Road bridge

The road bridge is part of the state road network of the canton of Bern and connects Tiefenau in the municipality of Bern with Worblaufen in the municipality of Ittigen . It is part of both Hauptstrasse 1, which connects Bern with Zurich , and Hauptstrasse 12 , which connects Bern with Basel via Solothurn .

The bridge was built between 1846 and 1851 on behalf of the city of Bern. The plans come from the Polish exile and cantonal chief engineer Jan Pawel Lelewel from 1843. The further execution took place after the decision in 1844 to build the bridge and Lelewel's death in 1847 by the architect Johann Rudolf Gatschet, Carlo Colombara was the building contractor. The conventional arch bridge consists of three arches, each 28 m wide. It is designed as a high bridge, i. that is, it spans the entire valley of the Aare. The foundation stone was laid on March 28, 1846. On June 11, 1847, the scaffolding collapsed, killing 26 people. After the bridge toll was lifted, the bridge, completed in 1851, was taken over by the canton in 1853.

The Bern-Zollikofen-Bahn and later the Solothurn-Zollikofen-Bern-Bahn also use this bridge between 1909 and 1969.

The bridge was renovated in summer 2008.

Railway bridge

The trains of today's Bern-Solothurn regional traffic , or RBS for short, have been using the double-lane railway bridge with footpath built right next to the road bridge since November 20, 1965 and use this route to reach the RBS station underground at Bern station. The bridge is officially named Aare Worblaufen . But both bridges are popularly known as the Tiefenaubrücke.

Construction of the railway bridge as a prestressed concrete arch bridge began in 1965. Its arch has a span of 97 meters, while the trough with the rails is 200 meters long.

With over 550 train journeys and up to 60,000 passengers daily, the bridge is one of the most frequented railway bridges in Switzerland. Extensive renovation work will be carried out between summer 2017 and autumn 2018.
