EUGENE (KMTR) – The graffiti on the I-5 highway’s sound wall stating “Ron Paul 2012” has returned.

More than a month ago, someone sprayed the graffiti onto the wall. ODOT quickly covered it with a white eco-friendly spray, but less than 24 hours later, the graffiti came back.

Nearest entrances to that location on the bike path include a residential way and over the pedestrian bridge from Gateway Mall.

Some residents believe the graffiti has some type of intent behind it. ODOT says the biggest problem they have now is finding another way to cover it.
