I have to admit, I've been afraid to cross the bridge as well. But I figure, they wouldn't let people drive over it constantly every day if it were too much more dangerous than driving in general is.
But I have a question to those that have crossed the bridge recently, do they take credit cards at the tolls now? Until fairly recently I don't remember there being credit card slots at any tolls, but they were present on the toll roads when I went to Chicago last month. It'd be great if they did, because I don't like carrying a bunch of cash on me when I ride.
