Strategies in Designing and Managing Bridges and Structures to Enhance Transportation System Resilience

This paper focuses on highway bridges and structures including tunnels, their importance within the transportation network, and efforts underway to address resiliency. Keeping the system functional throughout an extreme event cycle and beyond is also discussed. The Federal Highway Administration (FHWA) established several programs to increase the knowledge base for improving transportation system resilience, and to assist states.Disasters and disruptions continue to evolve in complexity, functional impact, economic cost, and in diversity of locations and types. Just focusing on weather, the National Oceanic and Atmospheric Administration’s (NOAA) ‘Billion-Dollar Weather and Climate Disasters’ study reports the U.S. sustained 250 weather and climate disasters from 1980 to 2019. These weather impacts caused overall damages/costs reaching or exceeding $1 billion (Consume Price Index, CPI, adjusted to 2019) and with a total cost exceeding $1.7 trillion. (https://www.ncdc.noaa.gov/billions/overview). Government and private entities at all levels are responding in various ways to effectively and efficiently respond to disasters and their effects. Within transportation, the Federal role is to coordinate with State Transportation Departments, Metropolitan Planning Organizations (MPOs) and with organizations representing the transportation field, such as the Transportation Research Board (TRB), and others.For conciseness, most of the discussions in this paper reference bridges. However, it is generally implied that the same concept applies to other highway structures unless specifically discussed separately.
