The purpose of the project is to make it possible to install noise barriers along Stanów Zjednoczonych Avenue, at the section from Bajońska St. to Międzynarodowa St., which will reduce noise emissions. The decision to rebuild them was made after conducting tests which showed significant exceedances of the permissible road noise level. In order to reduce it, a new, quiet road surface will also be made. Stanów Zjednoczonych Avenue is a section of Łazienkowska Road.
