Governor Schwarzenegger issued an apology Friday after California residents are up in arms that a flag mural — paying homage to victims of the 9/11 terrorist attacks — was painted over after the state ruled it was graffiti.

"It has come to my attention that Caltrans has recently removed a patriotic and meaningful flag mural that was painted on the side of Interstate 680 following the tragic events of 9-11. To do so only days before we celebrate our independence and reflect on the freedoms we are lucky enough to enjoy in America is unconscionable. I extend my apologies to the artists whose mural inspired drivers along 680 for over eight and a half years," the governor said in a statement.

His remarks come after state transportation workers on Thursday turned the 35-foot hillside mural on Interstate 680 in Silicon Valley back into a gray slab of concrete, KTVU-TV reported. The explanation? It simply had been put on a list for graffiti remove, one official said.

But the landmark had been a favorite among residents and motorists. "It just made me feel really patriotic just seeing it every day," motorcyclist Dave Freely told KTVU-TV.

The artist behind the mural, Eric Noda, was among those confused as to why the state suddenly deemed the flag graffiti and motioned to take it down. "It should not be classified as graffiti. I mean it was a well-done flag and I felt like it's part of America," said Noda said.

But the state apparently wasn't aware until now that the eight-year-old mural was on the state's highway right-of-way. Otherwise, it would have be removed a lot sooner.

The flag muralists vow to repaint the mural in time for the tenth anniversary of the terrorist attacks. But the state says they will have to go through an application process for permission to create "transportation art."
