On 1 May 2012, the EIB Complaints Mechanism (EIB-CM) received a complaint concerning the S17 expressway within the Eastern Poland Roads TEN-T project. The complainant alleged that the project promoter had decided not to install noise barriers in a residential area located in the vicinity of the S17 expressway across Dabrowica in Lublin. In this regard, the complainant observed that the residential buildings in the indicated area would be exposed to high levels of noise and pollution and, therefore, highlighted the necessity to install noise barriers in the contested area. Moreover, the complainant expressed his/her doubts about whether or not a future reassessment of noise and pollution, after the finalisation of works and during the operation of the project, will take place with a view to assessing the necessity to install additional noise barriers.
