That would be a legitimate time to soil your pants as an adult I think.
I'm no expert on structures, but lots of skinny, very tall bridge piles without lateral bracing doesn't instill a sense of confidence in me.
Apparently the bridge is 50 odd years old, but was re-furb'ed two years ago, and that the general community had reservations about driving over it. Hard to tell how wide spread the community concern was after the fact. It is fair to say that motorway bridges should not fall down. Maybe in very large earthquakes, perhaps, but just fall down, that shouldn't happen...

The 1,182-metre structure was inaugurated in 1967 and went through major reinforcement work in the 1990s.
Ansa cited a 2011 report by Autostrade per l'Italia, the Italian highways company, as saying that the bridge had been suffering from decay.
"Queues of cars and the volume of traffic provoke intense decay of the Morandi viaduct structure on a daily basis in the rush hours as it is subject to major demands," the report said, adding that the bridge was for this reason in need for continuous maintenance work.
Il Sole 24 Ore, Italy's financial newspaper, reported that the company had launched a 20-million euro call for tenders in April 2018 for "structural retrofitting" of the bridge.
The document said piers nine and 10 - the vertical structures holding the bridge up - were to be reinforced, while pier 11 had been strengthened in the 1990s.
After a pre-selection of the companies came to an end on June 11, winners would be selected by September. Pier nine was involved in today's collapse, according to the newspaper.
A bystander, Pietro M., told Ansa news agency he saw "lightning strike the bridge" just before the collapse, as a wave of bad weather was sweeping through Italy at the time.
Looks like they knew pier 9 needed strengthening, they just didn't get around to it in time...
A better view of what the piers and the spindly legs look like. I see the bridge in the background has even spindlier legs...

100's of bridges in Italy just like it and in the same condition

Here are some pictures of the strengthening work that had been carried out on the bridge previously.
The original suspension cables are encased in the concrete tendons with no opportunity to observe corrosion.
The portion of the bridge that failed had not been strengthened apart from bracketing to the upper portion.
