Road signs in different states say the same thing but are sometimes worded differently. Ok, that doesn't make much sense. Here are a few examples:
Bridge freezes before roadway
Bridge may ice in winter
Bridge may ice in cold weather
Watch for ice on bridge
Beware of icing on bridge
Bridge may ice quickly
Hawaii doesn't need a sign like that. They need one that says:
Narrow bridge with limited sight distance and low or no guard rails, but speeding sugar cane trucks and drunken surfers, plus sudden flooding and rock slides at both ends. High winds. Hang loose, Brudder.
