No. Those signs are actually maintained by TXDOT. I was testing a new graffiti remover on this. Just pulled off and did it. Took me about 5 minutes. I have spoken to TXDOT before and they have tried a different product that I gave them a sample for and they said it worked great. However they prefer to send 6 guys, 2 trucks, close off a lane of traffic for about an hour, and change the signs out.
