This is what you definitely don't want to see, especially if you're in a hurry; the KMI bridge onto the island going up, probably to accommodate a sailing boat with a tall mast. The sailors aren't popular at rush hour. "They just chug up and down the intracoastal with their engines on; they don't even put their sails up. Don't they know folks are trying to get to work/home/golf/the beach?" is a fairly typical comment.
Usually it comes down again fairly quickly but not before a substantial traffic jam's built up.
But interesting things can happen. I was once on one of the other bridges when there was an accident and the whole queue of cars had to reverse off it again. And the other day, a car stopped next to us that was almost identical to ours - a venerable Volvo estate. Hubby and the driver both simultaneously wound their windows down and simultaneously said, "How long have you had yours?"
And today, fortuitously, I was in just the right position to stop and look at a pair of nesting ospreys on a platform level with the bridge.
