Einhausung Schwamendingen (ZH) – Lärmschutzmassnahme

Short description

Construction of the new cut-and-cover tunnel with a length of 940 metres, a width of 30 metres and a height of 8 to 10 metres.

The project

As part of the work to enclose approximately one kilometre of the N01/40 national road between the motorway junction at Aubrugg and the Schöneich Tunnel, a commercial property is being created that is some 30 metres wide and is the only one of its kind in Switzerland. Plans are in place for a new overland park – a greenery-filled meeting place that runs the length of the building roof, which locals will be able to access via ramps, stairs and lifts. Its purpose is to reconnect the various parts of the district, enhance the quality of life in the local area, and provide a space for rest and relaxation. Encapsulating the motorway will virtually eliminate the negative impacts of noise and exhaust fumes that are usually associated with main roads. FEDRO, the Swiss Federal Roads Office, is funding this pioneering project together with the Canton and the City of Zurich.
