A new approach to improve safe exceptional transportation: a Proof of Concept in the framework of NRRP

Northeastern region of Italy is crossed by more than 54,000 annual exceptional transports. The secure transportation of these loads faces challenges due to road infrastructure constraints. Nowadays the movement of exceptional vehicles requires mandatory special permits granted by numerous road authorities, before embarking on a journey. This paper describes a transport corridor connecting the Swiss border with Maghera harbour passing through Milano analysed as a Proof of Concept (POC) in the framework of NRRP, providing a preliminary analysis of all the bridges identified along the path. The collected data encompass the parameters necessary for completing Level 0 criteria outlined in the Italian Guidelines for risk classification and bridge management, including security assessment and monitoring. Finally, 10 bridges are selected with the aim of developing experimental and simplified methodology for evaluating safety coefficients, focusing on the safe passage of Heavy Good Vehicles (HGVs).
