The transportation industry continues to face a range of unforeseen and evolving challenges to transportation assets and operations that affect the performance and resilience of transportation systems and networks. For example, significant disruptions to supply chains and traffic patterns were outcomes of the unanticipated collapse of the Key Bridge in Baltimore, Maryland.

NCHRP Research Report 1146: Risk Management at State DOTs: Building Momentum and Sustaining the Practice, from TRB's National Cooperative Highway Research Program, provides guidelines for state departments of transportation and other agencies to establish and maintain a risk management culture and practice.
