The project involves the construction of acoustic mitigation works in specific sections of the GRA through the installation or replacement of sound-absorbing barriers and the installation of sound-absorbing flooring in bituminous conglomerate. The A90 GRA motorway is an infrastructure of absolute importance characterised by very high vehicular flows throughout the day (in addition to peak hours, of course). The intervention will affect the southeast quadrant of the GRA, characterised by particularly high flows. ANAS S.p.A. commissioned an acoustic study for the restoration of the area. The planned noise abatement measures, which take into account the many critical issues in the area, are based on the study and the surveys carried out. 

The sections of the GRA subject to intervention are the following: 

1. ROMANINA AREA FROM KM 39+394 TO KM 40+290 

2. IFO HOSPITAL BETWEEN KM 54 +922 AND KM 55+217 

3. MEZZACAMMINO FROM KM 56+200 TO 57+600 

4. MAGLIANA AREA FROM KM 061+231 TO KM 061+331 

The interventions are part of the PCAR (Piano di Contenimento e Abbattimento del Rumore, i.e. Noise Containment and Abatement Plan), entirely developed by ANAS, which has already identified the financial coverage for a total amount of € 24 million. This will benefit not only civil housing but also public institutions such as schools and hospitals.
