Icy bridge signs have been around longer than warning labels on cigarette packages. I’ve never paid much attention to them. However, in winter 1972, I spun a friend’s car around on a bridge and smacked into a guard rail. Since then I’ve taken icy bridges seriously.
We moved from South Florida to North Carolina. I always figured they put those signs up for Floridiots because we really didn’t know bridges iced before roads. LOL
I appreciate those bridge warnings. If you are on an unfamiliar road, you may not even realize you are on a bridge until your car is sideways at 65mph.
