I image most of you have seen the video of the Francis Scott Key bridge in Baltimore getting hit my a ship. Went down like a kids toy.
I never thought much about it in the past, but things happen. One Sunday night we were going home to CT from Philadelphia. Heavy traffic on the GW bridge and we were stopped a minute. My daughter noticed the bridge moving and asked about it. I told here they were designed to move in high winds and storms, nothing to worry about. We continued on I95 north. Next morning, I have the news on and hear the Mianus River Bridge collapsed a bit after we crossed it.
I don't worry, but I do think about the possibility. I often cross the Skyway Bridge over Tampa Bay. It is the bridge rebuilt after the original went down in 1980. What remained has been converted to fishing piers.
