I don't have a problem with bridges. But the blue bridge bike trail is terrifying. I often walk my bike across.
It's made worse by being on a recumbent, I think. The problem with the lane is twofold - it's VERY narrow - so if you run into someone coming the other way or going another speed you are trapped. And, there is a double strobe-like effect from the posts. On one side the water is strobing by, on the other the traffic is strobing by.
The blue bridge is why I didn't even do that ride, even though it's in my hometown. I do the "river loop" all the time, though - just not with a whole bunch of other cyclists accross the blue bridge.
Glad you made it, hope you liked the rest of the ride.
