I'd like to know the cost of one of them.I want the contract to replace the ones that get taken out by the snow plows.Maybe they should be different colors for N,S,E,W.
Those signs are replacement for decent paving. Driving on MA roads is the pits. Asphalt peeling and chuck holes everywhere, but we now have some very nice signs.
He that would make his own liberty secure, must guard even his enemy from oppression; for if he violates this duty, he establishes a precedent that will reach to himself.

They have been in use for as long as I can remember, Are the signs you are referring to new? I think they were part of the highway building after WW2. If you were ever "on the road" you would have seen them in all states.
