SpanSight introduces a new paradigm in risk management by enabling real-time detection of near-miss vessel-bridge incidents.
Potentially hundreds of existing bridges over navigable waterways in the U.S. do not meet the vessel collision risk thresholds required for new bridge designs.
Due to limited funding, upgrading all of these structures is not feasible. A new approach to risk management is urgently needed.
AASHTO risk assessments rely on decades-old statistical models, extrapolated from sparse data and layered with engineering judgment to estimate the probability of bridge collapse.
Meanwhile, shipping traffic is increasing in both frequency and size—raising risk levels year after year.
But no-one is actually looking under our bridges for near-misses and close calls—the early warning signs of potential disasters.
