Episode Details

Phoenix just got a $38 million flood-fighting upgrade on I-17 — a gravity-powered drainage system that’s already slashing standing water in notorious underpasses. Gone are the clunky, 60-year-old pumps; now, angled pipes channel stormwater into retention basins and canals, keeping the freeway dry. ADOT’s big-picture plan includes 60+ pump stations moving 12,000 gallons per minute across the metro. Still, officials warn: don’t drive through deep puddles. Even with this tech, nature’s fury can overwhelm — so slow down, stay alert, and let authorities reroute if needed.
