Abstract
This article presents the data collected through an online survey of experts in the field of roadway and bridge inspection and repair, with an aim to understand and characterize post‐hazard restoration timelines. Accurate characterization of natural hazard resilience of a community requires a thorough understanding of the restoration process. However, empirical data are lacking to systematically relate damage induced by multiple hazards to functionality for both roadways and bridges. Existing models, relying on survey data which are tailored for seismic damage to bridges, either fail to capture the entire restoration timeline or do not account for intermediate stages of restoration. To address these gaps, an online survey of experts eliciting recommended traffic closures and the estimated time required to remove traffic closures/partial restrictions is presented herein. This article contains a detailed description of the survey methodology with insights into the data collected from a total of 29 respondents to enable its use in the area of transportation infrastructure risk and resilience analysis under natural hazards.
