Again, I support the improvements made and appreciate DOT's efforts, but...
Thousands of signs made to standard DOT green and reflective white/yellow colors, standard typeset and sizing rules, standard metal gauges and alloys, standard structural engineering, etc. - what is the consultant for? spell check?
No doubt DOT has high standards that are worthy of higher costs but that doesn't mean we should pay for bureaucratic overkill.
This reminds me of Pentagon purchasing - the $5,000 toilet, etc.
I would like to know what Disney pays for the signs on their roadways versus ones made by DOT.
