Wow. That really gives me the creeps. I have travelled over those bridges many a time, and they never bothered me much. The Sunshine Skyway Bridge in St. Pete was once a thrill for me until I went over it and viewed the drop-off from when the barge ran into it. The first time I went across the Mackinac Bridge in Michigan, I was not too thrilled. The wind was blowing mighty hard, and they had the speed limit set at 25 or some such because of the wind. Our vehicle was a-blowin too much for me. They were very close to shutting down the bridge that morning.
It'll be a while before those bridges are reopened. And it'll be a pain for travellers. But it'll be good for businesses that get the rerouted traffic.
The rail bridge in the background looks to be in better shape. I wonder if they have given any thought to trying to set up a commuter rail shuttle across the bay.
