Ive seen a video of people running under a bridge to ride out a tornado. Is that safe?
Absolutely not! Stopping under a bridge to take shelter from a tornado is a very dangerous idea, for several reasons: • Deadly flying debris can still be blasted into the spaces between bridge and grade — and impaled in any people hiding there. • Even when strongly gripping the girders (if they exist), people may be blown loose, out from under the bridge and into the open — possibly well up into the tornado itself. Chances for survival are not good if that happens. • The bridge itself may fail, peeling apart and creating large flying objects, or even collapsing down onto people underneath. The structural integrity of many bridges in tornado winds is unknown — even for those which may look sturdy. • Whether or not the tornado hits, parking on traffic lanes is illegal and dangerous to yourself and others. It creates a potentially deadly hazard for others, who may plow into your vehicle at full highway speeds in the rain, hail, and/or dust. Also, it can trap people in the storm’s path
