Hardbrücke restoration, Zurich
The 1,350-metre long structure is used by around 70,000 vehicles per day. The sealing and the pavement have exceeded their life spans, water is permeating the structure. As a result, the structure, which is comprised of six sections (a total of eight exit and entrance ramps), was in dire need of restoration.
