The Company has taken over the management of the A21 Turin-Alessandria-Piacenza, A5 Turin-Ivrea-Quincinetto, and A4/A5 Ivrea-Santhià connector highway sections, the Turin Ring Road Motorway System and its branches as of December 1, 2024, continuing, among other things, the activities already initiated by the previous operators (ATIVA S.p.A. and SATAP S.p.A.).
With regard to the A4/A5 Ivrea-Santhià motorway link, it is noted that the Company, in light of the emergency situation inherited in relation to the structural deficiencies identified on the “Camolesa” viaduct and upon the recommendation of the Granting Authority, the Ministry of Infrastructure and Transport, to the previous operator ATIVA S.p.A., has continued the construction and put into operation a temporary traffic lane on an embankment, to avoid the closure of the entire highway section and to allow users to travel on one lane in each direction without weight restrictions, pending the completion of the design of the viaduct retrofitting works, which are currently undergoing an environmental impact assessment at the Ministry of the Environment and Energy Security.
Work to upgrade the viaduct will begin as soon as all the permits required by current regulations—including environmental ones—have been obtained.
The temporary detour in place from approximately km 16+200 to km 15+600 may, depending on traffic volume, cause delays and/or traffic jams on holidays and weekends.
Specifically:
- On days preceding holidays, delays and/or traffic jams may occur for vehicles traveling from Milan/Genoa toward Aosta, starting from the interchange between the A4/A5 connector and the A4 Turin-Milan and A26 Genoa-Gravellona-Toce highways – A26/A4 Stroppiana-Santhià junction (km 23+000) up to the temporary detour (km 15+600);
- On holidays, when people are returning from mountain resorts, delays and/or traffic jams may occur for vehicles traveling from Aosta toward Milan/Genoa on the A4/A5 connector starting at approximately km 9+000 (after the Albiano exit at km 8+000) up to approximately km 16+200;
- On weekends, starting Friday evening from approximately 6:00 PM to approximately 10:00 PM and Saturday morning from approximately 8:00 AM to 10:00 AM, traffic delays and/or congestion may occur starting from the interchange between the A4/A5 connector and the A4 Torno-Milan and A26 Genoa-Gravellona-Toce highways – A26/A4 Stroppiana-Santhià junction (km 23+000) up to the temporary detour (km 15+600);
- On Sundays, when many people are returning from mountain resorts, traffic delays and/or congestion may occur on the route from Aosta toward Milan/Genoa, on the A4/A5 connector starting at approximately km 9+000 (after the Albiano exit at km 8+000) up to approximately km 16+200.
