The project involves an overhaul of the noise protection on the 15-kilometre section of the motorway between Wollishofen and Wädenswil. Along the entire project perimeter, two new noise barriers have been planned and two extended. The existing part has been replaced. A total of approximately 1.6 kilometres of noise protection was constructed using lava concrete.
