being under a concrete bridge and being on a bridge both scare me. I wonder when the last time it was inspected by Engineers and how often they are supposed to be inspected. I saw the devastation just after an earthquake in San Francisco how the overpasses were buckled and broken.
Oh, for heaven's sake! It's a bridge, will take all of one & half SECONDS', if that, to pass underneath in a car or bus!
If there's NO earthquake happening, you'd be quite safe! ALL bridges are regularly checked by Engineers'.
It's fascinating being on a boat or ferry going under a traffic bridge, listening to the 'kerplunk-kerplunk' noises of the cars' above, passing over the 'heat-stretchers'.
P.S. Being in a Tunnel doesn't worry me either. There's always light at the end of it!
Was on a boat, on the river, went under Railway Bridge, as train went across. Interesting sound to hear, as I travelled by train to/fro work for 40 years!
Most interesting experience was going under 'The Coathanger'. With the huge amount of traffic atop, the noise was deafening! Have done that 4 times, to/from Luna Park, by ferry from Circular Quay! Yay!
