Construction Signs

Construction zones use their own set of signs.  Construction signs are any sign with black text on orange.  The only exception is the End Road Construction Sign, which is red & black text on a white diamond.  Construction signs may also have a supplement plaque posted below them.  Below are the special signs only found in construction zones.
