Economic impact of bridge functionality loss from a resilience perspective: Queensferry Crossing, UK

Understanding the resilience of transport networks is critical for efficient asset management. This paper takes an innovative approach to studying operability Queensferry Crossing (QFC), UK, including cost–benefit aspects. A key driver QFC was increase A90/M90 link by reducing weather-related closures. The first closure in February 2020, when ice formed on superstructure cables and fell carriageway vehicles, creating a safety risk bridge users. closed 41 h and, this paper, estimated monetary losses are compared with those past Forth Road Bridge (FRB) costs potential mitigation measures then assessed context costs, thus improving QFC. Although has only been open 3 years, it already apparent that significantly more resilient than largely replaced FRB, whether considered as number, duration or closures will be substantially improved planned use FRB during future Investment potentially cost-effective solution although form any suitable prevention removal system is, yet, far from clear.
