Dan Henry symbols in Portland

What happened to the painted Dan Henry symbols when we reached Portland? They vanished and were replaced by small paper signs posted on telephone poles, etc. The new signs, while flourescent orange, were hard to read with their compressed font and tiny symbol, and you had to look up often to keep an eye out for them. Did Portland ban the painted symbols from their roads?
