BRIDGED²
Renovating Nydegg and Untertor Bridge.
Bern’s oldest bridges crossing the River Aare are being renovated: From 2027 to 2033, the Nydegg Bridge and Untertor Bridge will alternately be under construction. This website provides all relevant information about the project.
The renovations ensure both bridges’ safety for the next 40 years. Safety measures for pedestrians and cyclists will be improved as well as the living-quality surrounding the bridges. All under the preservation of the bridges’ historic appearance.
Traffic Phases
On November 30th 2026 site preparations start at Klösterlistutz. In February 2027 renovation works on the Nydegg Bridge start.
Detailed information about the different phases and associated traffic restrictions here.
Key aspects of the renovations
Road and sidewalks
On both bridges, the sidewalks will be widened, and the surface and paving stones will be replaced. In addition, the roundabout near the BearPark will be realigned.
Waterproofing and drainage
Both bridges will receive a new, continuous waterproof layer. At the same time, the drainage pipes will be replaced.
Support structure and natural stone
Damaged natural stones and joints will be repaired. On the Untertor Bridge, the railing anchors will be repaired. The new waterproof layer and the new tree pits will stabilize the existing retaining walls of the Nydegg Bridge to increase safety in the event of an earthquake.
Utilities and overhead wires
Energie Wasser Bern is replacing the water-, electricity- and gas lines on both bridges. BERNMOBIL is replacing the overhead wires for the bus line 12 on the Nydegg Bridge including the poles.
Accessibility
Barrier-free bus stops will be built, along with a new ramp-access to Klösterlistutz (Nydegg Bridge) and an expanded forecourt on Altenbergstrasse (Untertor Bridge).
Surroundings and quality of life
Lighting, trees, and seating will be replaced or restored based on historical models: at the Nydegg Bridge along Nydeggasse, and at the Untertor Bridge on the newly designed plaza on Altenbergstrasse.
Over 500 years of history
The Untertor Bridge is one of the oldest stone bridges in Switzerland. The natural stone arch of the Nydegg Bridge was long considered one of the largest in Europe. For centuries, these two bridges have shaped Bern’s cityscape: for transportation, defensive structures, landmarks, and symbols of the city.
