I wanted to enjoy the scenery (and amazing blue waters while driving across bridges!)... but concentrated on the road and not running into either side of these narrow bridges.
My dad gave me a good heads-up for these bridges... and I learned to check the sign whenever coming up to one (...having to either give way or having the right-a-way).
Some of these one-lane bridges are long!! ...A couple that I went over even had a spot or two along the way across to be able to pull over and let another car get around.
