National Bridge Impact Study

The state of bridges in the United States is becoming increasingly concerning as the functional age of many bridges is exceeding the original design life. Anticipating changing environmental conditions due to climate challenges, the Environmental Protection Agency established a research objective to analyze the potential impacts across more than 500,000 bridges in the National Bridge Inventory.

Resilient Analytics served as the lead consultant in assessing the national risk to bridges caused by increased water flow rates in waterways. The team was tasked with delivering adaptation costs for each bridge that crossed a waterway (approximately 250,000 bridges) based on condition and climate challenges. The team integrated structural, hydraulic and construction engineers to develop a final solution. Resilient Analytics developed new analysis functions to rapidly analyze bridge threats including structure, stream soil type and increased flow rates.
