Italy bridge designer had warned of corrosion risk 40yrs ago

The Italian engineer who designed the Morandi bridge that collapsed and killed 43 people warned of the risk of corrosion nearly 40 years ago. Riccardo Morandi wrote a report in 1979 stating the bridge would require constant maintenance to remove rust. He had recommended using an epoxy resin to cover the reinforcements with materials "of a very high chemical resistance".
