AUTOSTRADE PER L’ITALIA: PESCARA SECTION DEPARTMENT, THE 7-CM DISPLACEMENT DOES NOT CONCERN THE PILLARS OF THE CERRANO VIADUCT, BUT THE ADJACENT LAND IN THE 2016-18 PERIOD.PESCARA SECTION DEPARTMENT, THE 7-CM DISPLACEMENT DOES NOT CONCERN THE PILLARS OF THE CERRANO VIADUCT, BUT THE ADJACENT LAND IN THE 2016-18 PERIOD.
THE STRUCTURE IS CONSTANTLY MONITORED BY SENSORS, WHICH HAVE NOT RECORDED ANY NOTICEABLE MOVEMENTS.
NEW ANALYSES BY EXTERNAL EXPERTS, WHO HAVE CERTIFIED THE SAFETY OF THE STRUCTURE, HAVE BEEN CARRIED OUT ON BEHALF OF THE ITALIAN MINISTRY OF INFRASTRUCTURE AND TRANSPORT.
Pescara, 13 January 2020 - With regard to the comments that appeared in the media echoing the Avellino Gip's order of 18 December concerning the Cerrano viaduct, the Pescara Section Department of Autostrade per l'Italia would like to specify that the 7-centimetre displacement did not involve the pillars, but the maximum displacement of the ground near Pillar 1 recorded by the instrumentation over a period of 3 years (2016-2018). This value does not therefore refer to the viaduct pillars, which never made noticeable movements in the period considered.
The viaduct and the underlying area are constantly monitored from a geotechnical and structural point of view: special sensors have been installed on the structure, which, even in the last year, never detected any significant movement.
Following a "global safety check" recently carried out on the bridge and sent to the Italian Ministry of Infrastructure and Transport on 11 December 2019, the technical details of the foundations and hinges, carried out respectively by a pool of experts from La Sapienza University and the Italian Institute of Welding, have been sent to the Department. These analyses also confirmed the static safety of the structure.
