I have a real fear of bridges. I take them, but I really have a paralyzing fear. But if you can do it, I really admire you. Just make sure your bike is in good working order before you hit that bridge! Is it a bridge that often has debris? Have you had flats there before?
If you get a flat, walk the bike. Keep your mirror on so you can keep an eye on the oncoming traffic and have an emergency plan just in case.
